  • The illegal practice of slaughtering wild animals for food consumption in the Amazon region is a fact that brings with it, environmental and public health concerns. This habit is also present among rural producers in the municipality of Manicoré/AM. This practice, in addition to accelerating the process of extinction of some animal species, implies the consumption of products of animal origin not inspected by agricultural surveillance and inspection bodies of animal foods, which is an aggravating potential in the acquisition of diseases transmitted by this type of food. Illegality is also present in this area, tax and commercial issues and animal abuse. Environmental education is a tool that must be applied in all portions of the population, including in this context, the rural sector. Thus, the objective of applying a public opinion questionnaire was to be traced the profile of the consumption of wild animals. Of the total of 144 producers who were interviewed, 79.86% were male, 75% had a habit of consuming wild animal meat, with a periodicity of consumption once a week of 84.25%. Among the level of education of the participants, the training of incomplete elementary school was highlighted with 25%. In the form of the acquisition of clandestine meat, 29% perform the hunt itself and 44% gain from other people who have such a practice. The motivation for the consumption of these meats that stood out the most was the sensory item of flavor with 36.11%. Asked if they would leave the consumption of wild animals for the imminent risk of extinction, 62.04% would abandon such eating habits. Regarding the extinction of wild species, 51.39% believe that their consumption contributes to the extinction process. Thus, it was concluded that the consumption of wild animals in the municipality of Manicoré/AM is expressive, contrary to environmental and sanitary laws of products of animal origin. Thus, an awareness booklet was elaborated and made available on social and printed media, in an attempt to curb the consumption of wild animals.

  • In Bahia, citrus production occupies a prominent position, with high 178 socioeconomic relevance, characterized by its family-based exploitation model. 179 However, phytosanitary limitations often endanger the productive potential. 180 Huanglongbing (HLB) is the most devastating disease for citrus. Its vector is the 181 psyllid Diaphorina citri Kuwayama, 1908 (Hemiptera: Liviidae). This disease has 182 not yet been registered in Bahia, but the presence of the vector in the state may 183 contribute to the introduction of HLB. Thus, the economic impacts of the 184 introduction and dissemination of HLB in Bahia can be minimized by early 185 identification of this disease. The objective of this work was to make a 186 participative phytosanitary diagnosis with citrus growers of Recôncavo da Bahia, 187 as well as to register the perception of the farmers in relation to the HLB and its 188 vector, aiming at their awareness about the importance of the prevention to the 189 introduction of the HLB in Bahia. The diagnosis was made through individual 190 interviews, collecting information about the producer and containing questions 191 about the planted area, management, HLB identification and vector recognition. 192 The data were collected in five prominent municipalities in citrus production 193 located in the identity territory of Recôncavo da Bahia, namely Santo Antonio de 194 Jesus, Cruz das Almas, Governador Mangabeira, Muritiba and São Felipe. The 195 sample size took into account the data obtained from the Brazilian Institute of 196 Geography and Statistics (IBGE), using as reference the planted area of citrus. 197 In total, 109 interviews were conducted, with later delivery of a booklet with color 198 images of the vector and symptoms of the disease followed by a dialogue on 199 prevention methods, to facilitate understanding and recognition of the presence 200 of the vector and symptoms of HLB. In the next stage, visual inspections were 201 performed in the orchards to identify occurrence of psyllid in the production areas. 202 It was found that only 6% of farmers said they had some type of technical 203 assistance, 78% could identify changes due to pests in the orchard and 204 approximately 70% checked the health of the plants once a week. Only 6% of the 205 properties found psyllid eggs and 74% do not know the HLB. Even with the 206 tradition of citrus farmers, the use of technologies is little used. The lack of 207 technical assistance is a crucial factor for producers' misinformation about the 208 disease and its management. It is hoped that the diagnosis can contribute to 209 planning the resources that will be indispensable for the implementation of 210 actions in the agricultural defense, both preventive and, perhaps, control.

  • The objective of this study was to determine the prevalence of Caprine Arthritis Encephalitis (CAE), by performing a sorepidemiological survey in the municipalities of. Using the Immunodiffusion technique in Agarose Gel (IDGA). For this, 702 samples, belonging to 28 properties in the municipalities of the study - 14 in São Domingos (351 samples) and 14 in Valente (351 samples) were evaluated. During the visits, a questionnaire was applied to obtain information about the characteristics of sanitary, alimentary and reproductive management in each property. As for seroprevalence, 2.99% (21/702) of the samples presented positive serology for LVC; comparing seropositivity among municipalities, the results were: 2.85% (10/351) in São Domingo and 3.13% (11/351) in Valente. Regarding the number of seropositive properties, among the 28 participating properties, 17.86% (5/28) presented positive animals for goat lentivirus (LVC). The prevalence obtained for CAE positivity was 52.38% (11/21) and 47.62% (10/21) for the Alpine Parda breed and SPRD presenting significantly higher seropositivity (p <0.05) than the others races studied. The properties that presented positive animals, in their totality, used the semi-intensive system of creation. Animals attending agricultural exhibitions showed significant positivity compared to those who did not attend (p <0.05), besides being considered a risk factor. The most frequent diseases are vermin (92.86%), caseous lymphadenitis (78.57%), diarrhea (78.57%), and mastitis (75%). be the clinical change most frequently cited by the producers. These results suggest, therefore, the necessity of implementing a strict sanitary control for LVC through periodic examinations and elimination of positive animals.

  • Passion fruit crop is infested by several species of pests, mainly insects and mites that infest from the root to the fruit. Some pests are sporadic and other secondary due to the low level of incidence, not requiring the adoption of control measures. The manipulation of the agroecosystem caused by the intensity of management associated with the expansion of cultivated areas can provide favorable conditions for the emergence of phytosanitary problems, especially those related to the occurrence of pests like thrips, insects belonging to the order Thysanoptera. In Brazil, thrips have not been cited as key pests in the passion fruit crop. However, recently, damage have been reported in plantations in the Brazilian savannah biome. The objective of this study was to identify the species of thrips that occur in experimental planting area containing 12 passion fruit genotypes and evaluate a possible correlation between insect population and meteorological factors. The samplings were carried out in three flowers and three sprouts/genotype/evaluation. Six samplings were made during the period from October 2017 to February 2018. Inthe flowers, we used the method of beat, randomly, in the planting row corresponding to each genotype. Each flower was involved with a plastic bag (dimensions of 10 cmx 15 cm), making a slight movement to facilitate the fall of insects inside the plastic bag, which was subsequently sealed. The samples were identified and plastic bags containing the insects were kept in a polystirene box for transport to the laboratory of Entomology. Shoots with 3 to 5 expanded leaves containing apical buds were collected following the same procedure described earlier. Afterwards, in the laboratory, the samples were placed in a freezer at -5 °Cfor one hour to facilitate the screening. At this stage, the occurrence of thrips was registered in both flowers as in the apical buds. Thrips from each sample were quantified with the help of a brush under a stereomicroscope and packaged in plastic bottles type "eppendorf" (2 mL) containing alcohol 90% and sent to a taxonomist. A total of 1536 specimens of thrips were collected in association with flowers of passion fruit of the experimental orchard. There was a positive and significant correlation between thrips population and rainfall.In relation to the sprouts, the presence of thrips was not observed. It was verified the occurrence of thrips belonging to the Family Thripidae, of the genus Frankliniella. We observed the predominance of Frankliniella insularis (Franklin) in the following species of passion: Passiflora edulis Sims., P. cincinnata Mast., P. edulis Sims. f. flavicarpa Deg. and P. coccinea Aubl. Other species were detected as Frankliniella tritici (Fitch) (3 specimens) and Frankliniella gardeniae (Moulton) (1 specimen) associated with the flowers of P. cincinnata, genotype BRS Sertão Forte. In the period studied, thrips were not recorded in association with flowers of the species Passiflora laurifolia L., Passiflora mucronata Lam. and Passiflora alata Curtis. Such information may be interesting for plant breeders, which can make use of these non-attractive genotypes, considering the damage caused by this pest.

  • Bovine tuberculosis (BTB) is a zoonotic infecto-contagious disease characterized by the development of nodular and granulomatous lesions in the different organs of the organism. Surveillance in slaughterhouses through the detection of suggestive lesions on post-mortem examination associated with definitive complementary diagnostic techniques for Mycobaterium bovis constitute important tools in the epidemiological surveillance of the disease in the herds. This study, a pioneer in this type of research in Ceará, aimed to verify the occurrence of BTB in suggestive lesions obtained from cattle slaughtered in slaughterhouses under State Inspection Service (SIE), through the use of bacteriological and molecular methods. To that end, slaughter and post-mortem sanitary inspection of 57,347 cattle were monitored in three SIE slaughterhouses. Samples of lesions suggestive of BTB (n = 41) were collected, which were submitted to bacteriological analysis in StonebrinkLeslie (SL) and Lowenstein-Jensen (LJ) culture media, and the isolates submitted to Ziehl-Neelsen staining (ZN) for tintorial characterization of acid-fast bacilli (BAAR). Subsequently, the mycobacterial DNA of the isolates was extracted by thermal lysis and submitted to Spoligotyping technique for identification and genetic typing of the etiological agent. It was verified the occurrence of lesions suggestive of BTB in the post-mortem examination of bovine carcasses (0.071%) from 13 municipalities of Ceará, being bovine females over 36 months of age from the municipality of Iguatu the animals most affected by the disease. The lesions were nodular, with cheesy content, and were located mainly in the lung (95.12%), lymph nodes (58.53%) and liver (36.58%). Microbiological culture showed bacterial isolation (17.94%), with small, rounded, creamy-yellow colonies with irregular borders, with granular surface with average time for 28 and 45 day colonies on SL mediums and LJ, respectively. All ten isolated colonies were BAAR +. The genetic polymorphism analysis confirmed the presence of M. bovis in all isolates, and six spoligotypes were identified (SB0121, SB0295, SB1064, SB0120, SB0870 and SB0852). This genetic diversity suggests that the movement of cattle between properties and regions is an important factor for BTB transmission. The profiles SB1064 and SB0852 were unpublished and had not previously been reported in Brazil. The association between routine post-mortem inspection in slaughterhouses and bacteriological and molecular diagnoses were efficient methods for the isolation and identification of M. bovis strains obtained from suggestive lesions of BTB from cattle slaughtered in the state of Ceará. The relevance of the present study is to be the pioneer in this type of epidemiological investigation in Ceará, which will provide subsidies for the planning and execution of prevalence studies and adoption of strategies for the control of BTB in the state.

  • The bovine liver is one of the viscera that stands out for being an excellent food. In the routine of inspection is commonly condemned, considering that its metabolic functions makes it susceptible to several types of injuries. Hepatic abscesses are considered the biggest economic problem, both for producers and the refrigeration industry. Thus, the objective was to carry out a microbiological evaluation of hepatic abscesses of cattle slaughtered in a frigorific abactionor in the region of the Northeastern Semi-Arid II of Bahia. A total of 109 samples of bovine hepatic abscesses were collected in a slaughterhouse, with a State Inspection Service (SIE), located in the city of Ribeira do Pombal. Microbiological evaluation of all samples was carried out by means of isolation and identification, being cultured in BHI enrichment broth (Brain Heart Infusion), then in specific culture media and later biochemical tests were carried out to identify microorganisms. Bacteria were identified and cataloged. To obtain the results, a descriptive analysis was performed for the absolute and percentage frequencies. Of the 5,593 cattle slaughtered, 109 livers were convicted of an abscess, indicating a percentage of 1.94%. Of the 109 samples collected, 11 did not obtain the determined cause, since there was no bacterial development. However, 98 samples showed bacterial growth. Of these, 31 were classified as Gram-positive and 67 as Gram-negative. Gram-positive bacteria were identified as Staphylococcus spp. (35.48%), Streptococcus spp., Enterococcus spp. (16.12%), Microccoccus spp. (6.45%) and Peptostreptococcus spp. (6.45%). Gram-negative bacteria were identified as Enterobacter spp. (35.82%), Proteus spp. (17.91%), Klebsiella spp. (13.43%), Escherichia coli (13.43%), Serratia spp. (7.46%), Providencia spp. (5.97%) and Pasteurella sp. (5.97%). Therefore, it can be concluded that there are a variety of bacteria that cause hepatic abscesses in cattle, and that most of them can cause human infections leading to health damage. Thus, the inspection of livers should continue rigorously condemning cases of this pathology.

  • The objective of this study was to carry out a diagnosis of the hygienic-sanitary quality of raw milk, cooled or not, destined to a dairy for the manufacture of dairy products. Samples were obtained by collecting milk from all dairy supply properties in the Recôncavo da Bahia (nine properties). Samples were obtained using sterilized screw vials. For each property, three replications were done, with a four-day interval between them. After collection, the samples were kept in an isothermal box containing recyclable ice, and sent to the LCAA of the CCAAB of UFRB. In order to perform the microbiological analysis, culture media were used: Levine agar (EMB), Bile-Esculin agar and Baird-Parker agar enriched with egg yolk. All the properties analyzed in this experiment had a SCN count, with a mean maximum count of 5,173 log CFU / ml. The milk samples collected at the farms presented SCP counts lower than those established by IN51 (7 log CFU / ml). The present study showed that more than half of the analyzed properties (55.55%) had samples of milk contaminated by E. coli, with a maximum mean count of 5,751 log CFU / ml. For bacteria of the genus Enterococcus spp., There were growth of these microorganisms in 88.88% of the samples analyzed. It was observed that in spite of having found the presence of pathogenic bacteria in the sample analyzed, the milk was suitable for the production of derivatives, since the bacterial count was within the standards established by the legislation in force. It is important to review the acceptance patterns of these microorganisms, in order to avoid outbreaks of toxinfection in people who will consume milk and derivatives.

  • PARTICIPATORY PHYTOSANITARY DIAGNOSIS: TOOL FOR THE MANAGEMENT OF PESTS OF BAHIA RECÔNCAVO CITRICULTURE

  • Data: 24/08/2018

  • The importance of citriculture goes beyond the generation of foreign exchange into the Brazilian economy. The State of Bahia occupies a prominent position in the production of citrus fruits, is the fourth national producer and the first of the North and Northeast regions. Due to the intense occurrence of pests and diseases in crops, the productivity of Brazilian citriculture is constantly threatened. It is assumed that the lack of a defined public policy for citriculture, associated to the lack of adequate technical contingent to assist and support the management strategies of orchards, have resulted in a constant difficulty in dealing with phytosanitary occurrences. The present work was carried out with the objective of promoting a participatory phytosanitary diagnosis with citrus growers of the Recôncavo Baiano territory, to outline the socioeconomic profile of the citrus grower and to characterize the phytosanitary of the orchards. The structured interviews were applied to citrus growers from nine municipalities, Sapeaçu, Muritiba, Cruz das Almas, Governador Mangabeira, Cabaceiras do Paraguaçu, São Felipe, Castro Alves, Conceição do Almeida and Santo Antonio de Jesus, from September to December 2017. In order to identify the perception of the citrus trees in the recognition of the pests and associated symptoms, colored images were used. In a second stage, visual inspections were carried out in 10% of the orchards, an opportunity to confirm or not the occurrence of the plagues listed in the questionnaire. The size of the sample took into account the information of the Brazilian Institute of Geography and Statistics (IBGE) on area planted with citrus. In total, 255 diagnoses were performed. Approximately 82% of citrus farmers interviewed are family farmers who own plantations in areas of less than three hectares. It was observed that the advance of the occurrence of pests and their dispersion, together with the lack of adequate management, has led to the abandonment of the orchards or replacement of citrus by other crops. This may be associated with the lack of Technical Assistance and Rural Extension (ATER), since only 15% of the citrus farmers interviewed reported receiving some kind of technical assistance. The main phytosanitary problems observed were citrus black fly, ortézia, floral rot, grease spot, false rust and citrus variegated chlorosis (CVC). No report or observation of symptoms associated with Citrus Huanglongbing. For the continuity and maintenance of the citrus production chain in the Recôncavo da Bahia, there is a need to support citrus farmers in the control of pests that are already present and preventive measures to avoid the occurrence of new pests.

  • Fish is a food of high biological value, healthy and rich in proteins and lipids, composed of polyunsaturated fatty acids, but very susceptible to microbial deterioration, being necessary care from its capture until reaching the consumer. The objective of this study was to evaluate the quality of corvinas (Micropogonias furnieri) marketed in free trade fairs in the Recôncavo region of Bahia, using checklist, physicochemical and microbiological analyzes. Micropogonias furnieri samples were obtained from the free trade fairs of the municipalities of Cruz das Almas, Muritiba, Maragogipe, in the state of Minas Gerais, Brazil. The study was carried out at the Laboratory of Infectious Diseases of the Center of Agricultural, Environmental and Biological Sciences of the Federal University of Recôncavo, Cachoeira and Santo Amaro, from November 2017 to January 2018. In order to evaluate the hygienic-sanitary conditions, it was carried out at the fairs, check-list of compliance and non-compliance of good practices for food services, proving that 100% of these municipalities have free fairs classified as bad. The fish samples were submitted to physicochemical analyzes of temperature, pH, ammonia, sulfuric gas and cooking test. These were not shown to be statically effective as indicators of freshness of corvines in this study. Microbiological analyzes for the quantification of mesophilic aerobes, psychrotrophic aerobes, Staphylococcus aureus, Enterococcus spp., Molds and yeasts, the most probable number of total coliforms and thermotolerant coliforms and the presence of Salmonella spp., Showed that 100% of the samples were in disagreement with Resolution 12/2001. It was verified that the corvinas (Micropogonias furnieri) commercialized in the free fairs of these municipalities of the Recôncavo of Bahia are not of good quality, not respecting the federal legislations, being considered improper for the consumption, characterizing a potential risk to public health. Needing incentives to health education programs to inform the manipulators, traders and consumers, the need for care that must be taken during the handling and storage of food.

  • HAEMATOLOGICAL AND BIOCHEMICAL ASPECTS OF GOATS
    NATURALLY INFECTED WITH Corynebacterium pseudotuberculosis

  • Data: 23/03/2018
  • Mostrar Resumo
  • Caseous lymphadenitis is an infectious, chronic disease that has as its etiological
    agent the bacterium Corynebacterium pseudotuberculosis that affects goats. The
    animals are usually asymptomatic, having as main clinical manifestation the
    presence of abscesses in superficial lymph nodes. There are few hematological
    and serum biochemical studies that reflect the condition in the field. This work
    was carried out to evaluate the hematological and biochemical aspects of goats
    naturally i9nfected by Corynebacterium pseudotuberculosis. Samples of blood
    were collected from 55 adult, alpine brown, and crossbred goats, reared in a
    semi-intensive regimen of three farms located in the Recôncavo da Bahia, two
    in Cabaçeiras do Paraguaçu and one in Castro Alves. Blood was collected to
    perform the antibody test for C. pseudotuberculosis, blood count and serum
    biochemistry in addition to fecal samples for evaluation at the level of parasitism.
    Of the 55 goat samples analyzed by the test of indirect ELISA for anti-C.
    pseudotuberculosis antibodies, 34.55% (19/55) of the animals were positive and
    65.45% (36/55) negative. Plasma fibrinogen concentration, serum albumin
    concentration and enzymatic activity of AST differed between groups (p<0.05),
    with no significant differences observed in the other parameters observed.
    Hyperfibrinogenemia indicates an inflammatory process, as well as neutrophilic
    leukocytosis found in the mean of positive animal values, indicating chronic
    disease exacerbation. Hypoalbuminemia may indicate infection by
    gastrointestinal parasites, as well as may be a consequence of hepatic changes
    in CL, as evidenced by increased AST. High CPK in positive animals may be
    related to the semi-intensive rearing system. Most of the animals in the positive
    group had a body score between 3 and 4 (medium and fat) indicating good
    nutritional status. The most affected lymph nodes of the seroreagent animals
    were the pre-scapular cells being in agreement with the literature. The age group
    of 1 to 2 years of the animals in the positive group is probably due to the onset
    of the lesions caused by C. pseudotuberculosis and also the period in which the
    animals presented seroconversion, but they remained asymptomatic. Both
    groups presented high parasitic infestation with high values of O.P.G. and
    O.O.P.G., justifying hypoproteinemia and eosinophilia of the positive group.

  • Animal welfare of 80 goats was evaluated through social behavior,
    ambience and through the AWIN protocol. Of these, 14 goats were randomly
    selected to evaluate ingestive behavior. Assessments of social and ingestive
    behavior occurred at 10-minute intervals, weekly, lasting 12 hours, for 60 days. The
    microclimatic data were collected simultaneously at the evaluation of the animals, at
    intervals of two hours. After measuring the variables related to the environment, to
    ingestive and social behaviors, the data were compiled in a database, from which
    four Type Behaviors were obtained by means of an Ascending Hierarchical
    Classification (CHA) of the values of the Principal Components (CP) that explained
    53.67% of the observed variance. To evaluate the AWIN protocol, Person Correlation
    was performed between the first and second level variables (p <0.01 and p <0.05).
    Each type behavior obtained reflected the grouping of the behavioral patterns taking
    into account the ingestive behavior, social and its variation according to the
    ambience. The internal consistency of the types was guaranteed by the difference
    (3.17, p <0.01) between the eigenvalues of the first two CP. It was observed that the
    type-1 behavior concentrated the moments of better ambience, types 2 and 3
    concentrated the moments of worse ambience, type 3 also concentrated the
    agonistic interactions as a function of the radiation. In type 4, the social interactions
    observed as a whole occurred, this type being intermediate in relation to the
    ambience between types 1 and 2. A correlation was found between the AWIN
    variables analyzed. It was concluded that the bad ambience most of the time, as well
    as the low availability of forage, altered both the ingestive behavior and the social
    behavior of the goats. It was also concluded that the AWIN tool was efficient in
    evaluating animal welfare, although it did not evaluate deeply the effects of the
    ambience, especially in tropical climates. As a consequence animal welfare was
    considered poor in the present study.

  • The objective of the present study was to characterize and typify an occurrence of subclinical mastitis in caprine herds identifying their main, regional occurrence, prevalence and economic impacts. We studied 44 SPL (Milk Production Systems) in the region of Valente - BA in 2017. The UFRB under the number of online users (CONEP) - UFRB under the number (64519817.7.0000.0056) following the described methodologies by Foody, (2003) and Ramos (2008), related to seven main groups; cj1- Characteristics of the owner and rural property, cj3-Characterization of milk production and risk of mastitis, cj4-Management of food cj5-Management of milking cj6-ATER information and commercialization, cj7-Form of field. Age, body condition score, sieve test, CMT reaction (coagulation score 1-3) and non - dairy samples of 3 samples / SPL were analyzed for the analyzes (protein, lactose, st, esd, ccs and cbt). A comparison was made between the components, using means found by Malheiros Filho et al. (2014) and AFM (Multiple Factorial Analysis). Software R 2.15.0 and Factor Miner package were used in all analyzes. The dimension 01 was characterized by the variables related to the diversity of microorganisms in milk. The size 02 was characterized by the variables related to the reaction score of the animal to the CMT test and the size 03 related to the management in the milking mainly influenced by the note attributed by the milker regarding the importance of the cleaning of the ceilings of the animals. From the typology three types were obtained and the bacterium Streptococcus agalactiae isolated in all types. Type 01 showed high contamination by microorganisms, did not treat animals with antibiotics, high reaction to CMT (19.99%) and lower (R $ 938,90) revenue. Type 02 presented low bacterial contamination, treated animals with antibiotics, reaction to CMT in (20%), higher income (R $ 2823,49). Type 03 presented medium contamination by microorganisms, treated the herd with antibiotics, reaction to CMT of (20%) and income (R $ 1192,31). There was (p<0.001) for fat and total solids among the Types. There was a reaction to the CMT test for 67.81% of the animals and the diversity of microorganisms in the milk, CMT Reaction Score and grading attributed by the milker related to the ceiling hygiene of the animal were the main discriminatory variables for SPL.

  • ABSTRACT: Streptococcosis usually damages due to the great economic losses to the world fishing industry. It is necessary to develop diagnostic techniques for the rapid identification of the pathogen. The objective was verify the presence or absence of S. agalactiae bacteria in organs (brain, cephalic kidney and spleen) of Tilapia immunized against streptococci through PCR, use of different doses of commercial vaccine. For the extraction of DNA from bacterium, was performed the phenol chloroform protocol. After the PCR, the Streptococcus agalactiae was visualized in the chosen tissue fragments, and the mortality of the vaccinated animals was analyzed compared to the control. Through DNA extraction Streptococcus DNA amplification was observed directly from tissues that were reserved for this study. The percentage probability of negative organs was in the control (T1) 0% in all the samples and in the other treatments T2 75%; 33% and 58% already in T3 100%; 85%; 69% in the brain, kidney and spleen, respectively. The mortality in the control animals was 83% aganist 69 and 63% in the treatments that received 1 dose and 2 doses of the vaccine. Through the extraction of the bacterial DNA by the chloroform phenol protocol, it was possible to obtain the genetic material and to perform a good amplification by identifying the DNA of the bacterium through PCR in the tissues of the analyzed fish.

  • The goat is an animal species of great relevance in the Brazilian northeast, used for the production of milk and meat, serving as a source of income for small farmers, especially in family farming. Among the coccidia protozoa that infect goats, we can highlight Toxoplasma gondii, a major cause of abortions in this species. They are found high prevalence of toxoplasmosis in goat herds in several places, which generates considerable economic losses. These animals are infected through the horizontal route with ingestion of water or food contaminated with the oocysts eliminated by the definitive host and can be transmitted vertically, where the tachyzoites are passed to the fetus by the placenta, being a form of maintenance of the parasite in the herds. In order to perform a seroepidemiological survey of anti-T. gonddi in goats raised in the sisal region of Bahia state, 817 goat samples were analyzed by indirect hemagglutination (HAI) reaction. Among males and females, older than six months, coming from 49 rural properties distributed among the cities of Araci, Cansanção, Conceição do Coité, Itiúba, Monte Santo, Nordestina, Queimadas, Santa Luz, São Domingos and Valente, belonging to the Territory of Sisal. The seroprevalence obtained in HAI was 31.0% (254/817). Therefore, the results found in this study confirm the presence of the etiological agent in goat herds in the Sisal Territory, reinforcing the need for greater control, prevention and diagnosis in the sisal region.

  • POTENTIAL FOR THE TRANSMISSION OF THE CAUSAL AGENT OF Fusarium WILT OF BANANA BY THE BANANA WEEVIL

  • Data: 29/09/2017

  • Banana (Musa spp.) is one of the most consumed fruits in the world. It occupies the second place in volume of fruits produced in Brazil. Bahia is currently the largest banana producer in the country. However, phytosanitary constraints can cause significant losses, as is the case of Fusarium wilt, a disease caused by the fungus Fusarium oxysporum f. sp. cubense (Foc). Infection by this pathogen causes destruction of the vascular system, with severe impact on production. It is difficult to eradicate it due to its longevity, since it has the capacity to survive for several years in the soil, being easily disseminated through fungus spores. Presently, the presence of the banana weevil (Cosmopolites sordidus), a widespread insect in all Brazilian banana plantations, has been associated with the causal agent of Fusarium wilt, and in Australia this insect has been related as a vector of tropical race (TR4), a pathogen of quarantine importance for Brazil. Whereas banana weevil, when fed on rhizomes of infected plants, may harbor the spores of the causal agent of the disease in its body, its occurrence may aggravate the disease transmission and may interfere with its management. Two experiments were carried out with the following objectives: (1) to evaluate the potential of transmission of the causal/agent of Fusarium wilt by C. sordidus adults; (2) to determine a possible association between C. sordidus and Fusarium oxysporum f. sp. cubense (3) to evaluate the attractiveness to C. sordidus of different, healthy and infected, banana plant parts regarding to Fusarium wilt. In the first experiment, four banana cultivars (Grande Naine, Maçã, Prata Anã and Princesa) were evaluated as for the infestation by C. sordidus, associated or not with Foc. A completely randomized design was used in a split-plot scheme with ten replicates. The treatments were: 1) control, 2) infection with Foc, 3) infestation by C. sordidus, 4) infestation by C. sordidus + Foc (internally to the insect) and 5) infestation by C. sordidus + Foc (externally to the insect). The evaluated variables (plant height, pseudostem diameter and number of alive leaves) were submitted to analysis of variance and the means were compared by the Tukey test (p <0.05). There was an interaction between C. sordidus and Foc in the different banana cultivars tested by association with the pathogen in the body of the insects. In the second experiment, the attractiveness of rhizome, pseudostem and leaves of banana plants cv. Maçã, healthy and infected by Foc, to C. sordidus females was evaluated. The tests were done in arenas in a completely randomized design with 36 replicates for each part of the plant. In each arena, five females were released. The choice of females was observed after the 30-minute period. The variables evaluated were the number of insects in each of the treatments and the number of insects in the non-response area. The averages of the data were submitted to Student's t test (p<0.05). Females of C. sordidus responded positively to banana pseudostem and rhizome. In turn, the insect was less attracted by the odors of infected plant. This result indicates that the attractiveness of the insect to the plants is mediated by the volatile organic compounds. Knowledge about their behavior can be used to monitor and control the pest. With the existing risk of a possible introduction of Foc TR4, contingency measures should be established, since adults of C. sordidus can carry spores in their exoskeleton or internally, acting as vector of the pathogen.

  • Cysticercosis is a parasitic disease, considered zoonosis, caused by the presence of larval forms of Taenia saginata (Cysticercus bovis), bovine tissues and Taenia solium (Cysticercus cellulosae), in swine tissues, of which man is the definitive host, which ing viable cysticercus can contract teniasis. Bovine is the intermediate host that acquires Cysticercosis by ingesting T. saginata eggs from infected human faeces, which can subsequently contaminate pastures, vegetables, and water. This zoonosis is characterized by a low rate of technical development in animal husbandry and lack of basic sanitation. Both this parasitic disease and human teniasis can and should be controlled through basic sanitary measures. These measures are inspected by the sanitary inspection service inside the slaughterhouses, since it is frequently found in the slaughter line of the bovine species. The present study reports the prevalence of cysticercosis in cattle slaughtered in a refrigerator situated in the northeast of Bahia under the official inspection service, where 190,461 bovines were inspected between 2014 and 2016. The information regarding the names of the properties the total number of animals slaughtered in each batch and cases of cysticercus live 0.005% and calcified 0,63% in the lots evaluated. The presence of the parasite was detected in viscera such as liver and heart; head and tongue for a total of 1,204 animals. There was a higher prevalence of calcified cysticercus found in the liver 0.46% and in the heart than live cysticercus 0.14% found in all studied parts.

  • Milk is an alternative source of proteins accessible to the low income
    population, which is generally lacking in animal protein, proving the socioeconomic
    importance of this food. In public health, particularly in the area of sanitary food
    surveillance, Staphylococcus aureus, the main staphylococci of positive coagulase, is
    considered one of the most frequent cause of outbreaks of foodborne diseases. Milk
    and milk products are among the foods most involved in the outbreaks identified and
    studied. The objective of this study was to evaluate the quality of pasteurized milk
    with state inspection by the positive coagulase staphylococci, its antimicrobial
    resistance and the ability to form biofilm. The study was carried out in Alagoas and
    75L of pasteurized milk were collected from five processing plants and three different
    lots in the municipalities of Maceió, Coruripe, Capela, Chã Preta and Quebrangulo.
    Positive coagulase staphylococci (PCS) was performed using Baird-Parker Agar
    medium, rabbit plasma and brain-heart infusion broth. The PCS were submitted to
    the antibiogram by means of inoculation in Müller Hinton broth and the discs were
    applied with the drugs: gentamicin (5μg), amoxicillin (10mcg), polymyxin (300mg),
    erythromycin (10μg), penicillin (10μg), ampicillin (10μg), tetracycline (30μg),
    sulfazotrim (25μg) and cephalexin (30μg). The phenotypic characterization of PCS
    was also performed by the ELISA plate adhesion method for biofilm formation. Of the
    75 samples, 4 (5.3%) samples were identified with PCS. The count ranged from
    1,2x104 a 2,6x105CFU/mL-¹. Isolated PCS showed 100% sensitivity to all
    antimicrobials tested and none were biofilm forming. The quality of pasteurized milk
    with state inspection of the study in relation to the presence of coagulase positive
    staphylococci is inadequate for consumption. The sensitivity of PCS to all
    antimicrobials and non-biofilm formation reduces the risk that these microorganisms
    could cause to public health.

  • The objective of this work was to evaluate the effects of different
    percentages of sodium chloride on the production and quality of pork. A control
    sample (without addition of NaCl) and four levels of sodium chloride (2.5%, 3.5%,
    4.5% and 5.5% NaCl of meat weight) were used, with three replicates per treatment.
    The addition of sodium chloride significantly reduced the values of water retention
    capacity and weight loss per cooking, relative to the control. The concentrations of
    4.5 and 5.5% presented the lowest values of water activity. The treatment with
    addition of 3.5% of NaCl had the highest hardness value 0.173 Kgf N.s-1. There was
    loss of luminosity during the salting process, the concentrations of 2.5 and 4.5% of
    NaCl presented the lowest values of the red index, the average values of the yellow
    index were also influenced by NaCl addition, being lower than determined in control.
    All treatments had recommended microbiological levels suitable for human
    consumption. In the sensorial evaluation, processed pork with the concentrations of
    2.5%, 4.5% and 5.5% of NaCl obtained the best results. Therefore, because of the
    5.5% treatment obtained the best results in Aw 0.96 and in the hardness 0.126Kgf
    N.s-1, we conclude that this content can be used in the production of swine sun meat.
    New studies with refrigeration time and higher levels of NaCl are recommended, in
    order to evaluate other impacts on the results of microbiological evaluation and
    softness of pork.

  • Bovine Tuberculosis (TB) is an infectious disease caused by
    Mycobacterium bovis, and is usually characterized by the formation of nodular
    granulomas known as tubers. Although defined as a debilitating chronic disease,
    Bovine Tuberculosis (TB) may occasionally present an acute, rapid and progressive
    course. It is a zoonosis that has as its main reservoir cattle, but infects a wide variety
    of animal species among them being human. The objective of this study was to verify
    the frequency of condemned carcasses with lesions suggestive of Bovine
    Tuberculosis in a slaughterhouse in the municipality of Santo Antônio de Jesus-Ba
    from January 2007 to December 2016 and to verify the statistical correlation between
    Human Tuberculosis TH) and Bovine Tuberculosis (TB) with the municipalities of
    origin and the reported cases of HT of these municipalities. 857,776 cattle and 178
    carcasses were slaughtered in this period with lesions suggestive of Bovine
    Tuberculosis (TB), with a frequency of 0.020%. These frequencies varied with higher
    percentages in 2008 and 2009 and lower percentages in 2011 and 2014. In the
    mentioned period, a total of 64,114 cases of HT were reported in the municipalities
    from which the animals that originated the condemned carcasses originated and 178
    condemned carcasses with suggestive lesions of TB. A positive correlation was not
    observed between the variables TB and TH, which was very low and directly
    proportional (ρ = 0.133), that is, there was no significant correlation between the
    variables.

  • Casey lymphadenitis is a chronic disease, characterized by the
    presence of abscesses in the lymph nodes and organs of production animals, and its
    etiological agent is Corynebacterium pseudotuberculosis. The transmission is mainly
    through wounds, that is, direct contact of animals carrying the disease with the
    healthy ones. Control measures are vaccination and isolation of infected animals.
    However, the available vaccines do not provide the necessary protection against
    infection or have not yet been sufficiently tested in the field. The objective of this
    study was to evaluate the humoral immune response of serum samples from goats
    inoculated with a lyophilized attenuated vaccine using the 1002 strain of C.
    pseudotuberculosis by means of an indirect ELISA with BHI antigen. 100 goats, two
    to three years old, were divided into 5 groups (G1 to G5) with 20 animals each.
    Groups 1 and 2 received a dose of 107 CFU on day zero and at 21 days G2 was
    revaccinated. Groups 3 and 4 received a of dose 106 CFU on day zero and at 21
    days G4 was revaccinated. Group 5 was considered the control. The animals were
    followed serologically and clinically for 364 days. The sera collected from the goats
    were analyzed by the indirect ELISA technique. Despite the O.D. varied during the
    experiment, there was no statistical difference (p>0.05) between the different doses
    tested and times of revaccination between the groups. However, it could be inferred
    that 106 CFU dose is more indicated than 107 CFU in immunization of goats, since a
    greater loading of the immunogen would not be required for stimulating the humoral
    response according to the protocol followed in the experiment. In addition, the
    animals showed antibody production throughout the study, this situation indicates
    that lyophilized strain 1002 was able to induce an immune response for at least one

In several countries this parasite causes reproductive disorder in sheep and consequently economic impact in the sheep industry. More over it is a cosmopolitan zoonosis that causes serious damage to public health since it affects pregnant women and immunosuppressed patients. The aim of this study was to determine the seroprevalence in sheep slaughtered in a slaughterhouse under Federal Inspection in the State of Bahia and list the risk factors to the occurrence of the disease. serum samples from 227 sheep that were collected were used in a slaughter house refrigerator under Federal Inspection and subjected to hemagglutination reaction Indirect (HAI) securities ranged from 1:32 to 1: 4096. Getting a seropositivity of 40.53% (92/227). There was a higher frequency in the titration 1:32 (33.34%) and 1:64 (35.9%). There was no positive correlation between the variables studied and found seropositivity. However, according to the findings of this study there was a high seroprevalence of anti T. gondii IgG antibodies in sheep slaughtered in a slaughterhouse under Federal Inspection for human consumption.

  • Continuous production intensification in the poultry industry provides favorable conditions for the occurrence and spread of some pathogens, such as Escherichia coli (E. coli), responsible for the avian colibacillosis. This disease can lead to septicemia, cellulitis, chronic respiratory disease, among others, resulting in severe economic losses because mortality, morbidity and its consequences on the production chain. This study aimed to isolate E. coli of liver, lungs and intestines from chickens sentenced for septicemia in a slaughterhouse poultry under state inspection regime in Bahia, and to evaluate the antimicrobial resistance profile of E. coli isolated strains. In 09 days, 243,000 poultry have been slaughtered; of these, 52 were condemned for septicemia, whose livers, lungs and intestines were collected and sent for analysis, totaling 156 samples. Was used by direct culture of the samples in selective media and biochemical tests for identification. Bacterial growth was observed in all the analyzed samples of viscera, being E. coli isolated in 86.5% of carcasses (45/52). Of the total of 156 samples analyzed, 58.3% were positive for E. coli, the microorganism being found in 57.7%, 55.8% and 61.5% of the liver, lung and intestine samples, respectively. Were isolated 09 strains of E. coli which have been subjected to the susceptibility test for 06 antibiotics used in veterinary practice. None of the strains were sensitive to all antibiotics tested, but it was found a large number of multidrug-resistant samples. The antibiotic erythromycin was presented the highest bacterial resistance (77.8%), followed by sulfonamide and tetracycline (55.6%). The other antimicrobials (ampicillin, cephalexin and sulfamethoxazole-trimethoprim) had moderate antibacterial activity (44.4%).The high rates of resistance and multidrug resistance of E. coli, to antibiotics tested in this study, highlight the need for the correct use of these drugs in creations of commercial poultry in order to avoid further trouble in the control and treatment of colibacillosis and other diseases caused by bacteria.

  • Brazil is the largest exporter of chicken meat in the world and Brazilian law stipulates
    that every animal to be slaughtered suffer some kind of desensitization as Normative
    Instruction N° 3, being the electronarcosis the only method of stunning used in the
    state of Bahia and the most used for stunning of animals. The method uses

    are well above those recommended by the MAPA which advocates rates between 1
    and 2 % is possible to conclude that electronarcosis is not a satisfactory system to
    stun broiler chickens and is a likely cause of stress, pain and suffering and BEA does
    not meet the system as stunning. Excess tecnopatias shown in carcasses of birds
    exposes this system being very aggressive and not very satisfactory as a method for
    stunning and with regard to their well-being.
