A resistência antimicrobiana é uma questão atual e muito importante para a saúde pública, geralmente associada ao uso indiscriminado de antimicrobianos na produção animal. Diante disso, foi investigado o perfil de sensibilidade-antimicrobiana em isolados bacterianos de suínos com sinais clínicos respiratórios no Brasil. Foram estudadas 96 isolados provenientes de 51 granjas de suínos do Brasil. O método de disco-difusão foi empregado usando 14 antimicrobianos: amoxicilina, penicilina, ceftiofur, ciprofloxacina, enrofloxacina, clortetraciclina, doxiciclina, oxitetraciclina, tetraciclina, eritromicina, tilmicosina, florfenicol,lincomicina e sulfadiazina/trimetoprim. Streptococcus suis e Bordetella bronchiseptica foram os patógenos que apresentaram maiores níveis de resistência. Haemophilus parasuis apresentou altos níveis de resistência à sulfadiazina/trimetoprim (9/18=50%). Observou-se que isolados das regiões Centro-Oeste e Sul apresentaram quatro vezes mais chance de serem multirresistentes do que os isolados da região Sudeste. A maioria foi resistente a pelo menos um agente antimicrobiano (98,75%; 158/160) e 31,25% (50/160) das estirpes isoladas eram multirresistentes. No geral, os resultados do presente estudo mostraram grande nívelde resistência à lincomicina, eritromicina, sulfadiazina/trimetoprim e tetraciclina entre patógenos respiratórios bacterianos isolados de suínos no Brasil. Os altos níveis de resistência antimicrobiana em patógenos bacterianos respiratórios em suínos reforçam a necessidade do uso criterioso de antimicrobianos na suinocultura brasileira. | Antimicrobial resistance is a current and important issue to public health, and it is usually associated with the indiscriminate use of antimicrobials in animal production. This study aimed to evaluate the antimicrobial susceptibility profile in bacterial isolates from pigs with clinical respiratory signs in Brazil. One hundred sixty bacterial strains isolated from pigs from 51 pig farms in Brazil were studied. In vitro disk-diffusion method was employed using 14 antimicrobial agents: amoxicillin, penicillin, ceftiofur, ciprofloxacin, enrofloxacin, chlortetracycline, doxycycline, oxytetracycline, tetracycline, erythromycin, tilmicosin, florfenicol, lincomycin, and sulfadiazine/trimethoprim. The majority of isolates were resistant to at least one antimicrobial agent (98.75%; 158/160), while 31.25% (50/160) of the strains were multidrug resistant. Streptococcus suis and Bordetella bronchiseptica were the pathogens that showed higher resistance levels. Haemophilus parasuis showed high resistance levels to sulfadiazine/trimethoprim (9/18=50%). We observed that isolates from the midwestern and southern regions exhibited four times greater chance of being multidrug resistant than the isolates from the southeastern region studied. Overall, the results of the present study showed a great level of resistance to lincomycin, erythromycin, sulfadiazine/trimethoprim, and tetracycline among bacterial respiratory pathogens isolated from pigs in Brazil. The high levels of antimicrobial resistance in swine respiratory bacterial pathogens highlight the need for the proper use of antimicrobials in Brazilian pig farms.

Javalis mantidos em criatórios comerciais utilizam os dentes caninos como mecanismo de defesa e ataque a fim de expressar seus instintos naturais, o que pode resultar em fraturas dentárias e da mandíbula propriamente dita. Desta forma, propiciar a dessensibilização local do nervo alveolar inferior é essencial para a execução de procedimentos terapêuticos na cavidade oral destes animais. Logo, objetivou-se realizar a morfometria do forame mandibular desta espécie a fim de correlacioná-lo com as estruturas mandibulares, inferindo, também, sobre a forma mais segura de realização da referida técnica nos espécimes. Para tanto, foram utilizadas seis hemimandíbulas de Sus scrofa scrofa jovens, a partir das quais foram realizadas as mensurações propostas. Em média, a margem lateral do processo condilar distanciou-se 142,43 mm da raiz do dente incisivo medial inferior; o eixo longitudinal do corpo da mandíbula mediu 22,3 mm ao nível do diastema existente entre o quarto dente pré-molar e o primeiro dente molar inferiores; e o forame mandibular, a partir do extremo caudal de sua margem ventral, posicionou-se a 26,6 mm da margem ventral do ângulo da mandíbula neste nível, 34,92 mm da margem medial do processo condilar, e 38,63 mm do extremo dorsal da margem caudal do processo coronóide. Na falta de diferenças estatisticamente significantes, e observando que o acidente ósseo estudado posicionou-se no ramo da mandíbula, indica que o procedimento proposto deva ser realizado a partir da introdução da agulha em sentido oblíquo rostroventral por 2,0 cm e angulada a 60º com o referencial anatômico criado pela delimitação medial obtida pelo apoio do dedo polegar na margem lateral do ramo da mandíbula, ventralmente ao arco zigomático,preservando as estruturas próximas e definindo-se uma metodologia anestésica inédita para os Javalis. | Boars kept on commercial farms use their canine teeth as a mechanism of defense and attack in order to express their natural instincts, which could result in fractures of the teeth and jaws. Thus, utilizing local desensitization of the inferior alveolar nerve is crucial for executing therapeutic procedures in the oral cavities of those animals. Then, the goal is to carry out the morphometry of the mandibular foramen of that species, correlating it with the mandibular structures, while doing so in the safest manner for the animals. For that purpose, six hemimandibles of young-aged Sus scrofa scrofa were used, from which the proposed measurements were taken. On average, the lateral margin of the condylar process stood 142.43 mm away from the root of the lower medial incisive tooth. The longitudinal axis of the body of the mandible measured 22.3 mm at the level of the diastema that exists between the fourth lower premolar tooth and the first lower molar tooth. The mandibular foramen, from the caudal limit of the ventral margin, would be positioned at26.6 mm from the ventral margin of the angle of the mandible in that level, 34.92 mm away from the medial margin of the condylar process, and 38.63 mm away from the dorsal limit from the caudal margin of the coronoid process. The lack of statistically significant differences, and observing that the osseous accident under scrutiny had been positioned in the ramus of the mandible, indicated that the proposed procedure should be performed from the introduction of the needle in an oblique and rostrodorsal direction for 2.0 cm, and angulated at 60º with the anatomic reference created by the medial demarcation obtained via the support of the thumb on the lateral margin of the ramus of the mandible, ventrally to the zygomatic arch, all while preserving neighboring structures and establishing an unheard-of anesthetic methodology for boars.

Foi avaliada a eficiência do decocto das folhas de cajá (Spondias mombin L.) como antisséptico no pós-cirúrgico de gatos submetidos à orquiectomia e ovariosalpingohisterectomia. Para tal, foram submetidos à castração 45 gatos sem raça definida, divididos em três grupos. O primeiro grupo como controle positivo com Solução Alcoólica de Clorexidine a 0,5%; segundo grupo controle negativo com água destilada estéril; e o grupo teste com o decocto de cajá à concentração de 100 mg/mL. Todos os animais, independentemente da idade e sexo, tiveram cicatrização visível em tempo similar. Animais tratados com o decocto apresentaram uma redução significativa do crescimento bacteriano. Além disso, observou-se uma melhor cicatrização das feridas cirúrgicas dos animais tratados no grupo teste. Todas as estirpes bacterianas isoladas apresentaram halo de inibição para clorexidine e para Spondias mombin L. Portanto, o decocto das folhas da Spondias mombin L. apresentou eficácia antisséptica nas feridas cirúrgicas de gatos submetidos à orquiectomia e ovariosalpingohisterectomia. | This survey evaluated mombin leaves (Spondias mombin L.) decoction efficiency as an antiseptic during post-surgery period on cats submitted to orchiectomy and ovariosalpingohisterectomy. For this purpose, 45 castrated mongrels cats were divided into three groups, the first group as a positive control using 0.5% chlorhexidine-alcohol solution, the second a negative control group using sterile distilled water and, finally, the test group using mombin leaves decocted with a concentration of 100 mg/mL. All animals, independent of age and sex, had visibly healed in most cases in a similar time. Animals treated with mombin leaves decoction presented a significant reduction of bacterial growth. In addition, the animals treated in the test group had better surgical wound healing. All isolated bacterial strains presented inhibition halo for chlorhexidine and for Spondias mombin L. Thus, the decoction of Spondias mombin L. leaves proved antiseptic efficacy in the surgical wounds of cats submitted to orchiectomy and ovariosalpingohisterectomy.

Foram avaliados os efeitos do aumento dos níveis de quitosana (CHI) sobre o perfil e as perdas fermentativas, a composição química e degradação in situ da silagem de cana-de-açúcar. Os tratamentos foram: 0, 1, 2, 4 e 8 g de CHI / kg de matéria seca (MS). Foram utilizados vinte silos experimentais (tubos de PVC com 28 cm de diâmetro e 25 cm de altura). Areia (2 kg) foi adicionada na porção inferior de cada silo para avaliar as perdas por efluentes e os silos foram pesados 60 dias após a ensilagem para calcular as perdas por gases. Amostras foram coletadas do centro da massa do silo para avaliar a composição química, degradação in situ, perfil fermentativo e a contagem de fungos e leveduras da silagem. Os dados foram analisados como um delineamento inteiramente casualizado e o efeito do tratamento foi decomposto usando regressão polinomial. A CHI aumentou linearmente a concentração de ácido acético e N-NH3, enquanto diminuiu a contagem de leveduras e bolores e a concentração de etanol. Os níveis intermediários de CHI (de 4,47 a 6,34 g/kg MS) mostraram os menores valores de perdas por efluentes, gases e totais. Houve efeito quadrático da CHI sobre o teor de carboidratos não fibrosos, fibra em detergente neutro e ácido e sobre a degradação in situ da MS. Os menores teores de fibras foram observados com níveis de CHI entre 7,01 e 7,47 g/kg MS, enquanto que os maiores teores de carboidratos não fibrosos e degradação in situ da MS foram encontrados com 6,30 e 7,17 g/kg MS de CHI, repectivamente. A CHI aumentou linearmente as concentrações de ácido acético e N-NH3, enquanto reduziu linearmente a concentração de etanol e a contagem de fungos e leveduras. Desta forma, níveis intermediários de CHI, entre 4,47 e 7,47 g / kg de MS, diminuem as perdas fermentativas e melhoram o valor nutricional da silagem de cana-de-açúcar. | This study aimed to evaluate the effects of increasing levels of chitosan (CHI) on sugarcane fermentation profile and losses, chemical composition, and in situ degradation. Treatments were: 0, 1, 2, 4, and 8 g of CHI/kg of dry matter (DM). Twenty experimental silos (PVC tubing with diameter 28 cm and height 25 cm) were used. Sand (2 kg) was placed at the bottom of each silo to evaluate effluent losses, and silos were weighed 60 d after ensiling to calculate gas losses. Samples were collected from the center of the silo mass to evaluate silage chemical composition, in situ degradation, fermentation profile, and mold and yeast count. Data were analyzed as a completely randomized design, and the treatment effect was decomposed using polynomial regression. Chitosan linearly increased acetic acid and NH3-N concentration, while yeast and mold count, and ethanol concentration decreased. Intermediary levels of CHI (from 4.47 to 6.34 g/kg DM) showed the lower values of effluent, gas, and total losses. There was a quadratic effect of CHI on the content of non-fiber carbohydrates, neutral and acid detergent, and in situ DM degradation. The lowest fiber content was observed with levels between 7.01 and 7.47 g/kg DM, whereas the highest non-fiber carbohydrate content and in situ DM degradation were found with 6.30 and 7.17 g/kg DM of CHI, respectively. Chitosan linearly increased acetic acid and NH3-N concentration, whereas it linearly reduced ethanol concentration and count of yeast and mold. Thus, intermediary levels of CHI, between 4.47 and 7.47 g/kg of DM, decrease fermentation losses and improve the nutritional value of sugarcane silage.

A contaminação do solo por fezes de cães e gatos pode se tornar um problema de saúde pública devido à transmissão de vários agentes etiológicos que causam zoonoses. Este estudo objetivou verificar a ocorrência de geohelmintos no solo de praças públicas do município de Rio Branco, estado do Acre, Brasil. Cinco praças públicas foram selecionadas e amostras de solo foram colhidas entre abril de 2014 e março de 2015. As amostras foram processadas pelos métodos de Baermann-Moraes e centrífugo-flutuação. A positividade observada para geohelmintos foi de 25% para Toxocara spp., 6,6% para a Superfamília Ancylostomatoidea e 1,6% para Trichuris spp.. Medidas devem ser implementadas para prevenir a livre circulação de animais nestes locais, bem como a desverminação de cães e gatos de rua e a implementação de políticas de adoção e controle populacional de cães e gatos.Palavras-chave: Contaminação do solo.

Osteíte deformante (Doença de Paget) é um distúrbio ósseo crônico caracterizado por reabsorção óssea excessiva mediada por osteoclastos, seguida por nova formação óssea. O presente trabalho relata essa condição em uma serpente jararaca-ilhoa (Bothrops insularis) do Brasil de 18 anos. O paciente apresentou inicialmente anorexia e um inchaço no primeiro terço médio da coluna associado com a incapacidade locomotora. O diagnóstico foi estabelecido com o apoio de radiografia, ultrassonografia, tomografia computadorizada, citologia e cultura microbiológica. O diagnóstico por imagem mostrou alterações ósseas, fusão de vértebras e proliferação óssea. A citologia mostrou células sanguíneas como heterófílos tóxicos, monócitos reativos, células sanguíneas jovens e policromasia compatíveis com um processo infeccioso. A cultura bacteriana identificou uma cepa de Enterococcus faecalis suscetível à ampicilina. O tratamento com antibióticos foi iniciado imediatamente, mas a serpente morreu 25 dias depois. Histopatologicamente, o tecido ósseo mostrou um espessamento generalizado das trabéculas vertebrais. Portanto, foi demonstrado pela primeira vez a presença de E. faecalis associada ao desenvolvimento de osteíte deformante em uma serpente. | Osteitis deformans (Paget’s disease) is a chronic bone disorder characterized by excessive osteoclast-mediated bone resorption followed by new bone formation. The present paper reports this condition in an 18-year-old captive golden lancehead (Bothrops insularis) from Brazil. This patient initially exhibited anorexia and swelling in the middle third of the spine associated with locomotor disability. For diagnosis, radiography, ultrasound, computed tomography, cytology, and microbiological culture were performed. Diagnostic imaging showed bone changes, vertebral fusion, and bone proliferation. Cytology revealed blood cells how toxic heterophiles, reactive monocytes, young red blood cells, and polychromasia compatible with an infectious process. A bacterial culture identified an ampicillin-susceptible strain of Enterococcus faecalis. Antibiotic treatment was promptly started, but the snake died 25 days later. Histopathologically, the bone tissue showed a generalized thickening of the vertebral trabeculae. For the first time, the presence of E. faecalis associated with the development of osteitis deformans in snakes was presented.

O método de reprodução mais utilizado em bovinos de corte no Brasil é a monta natural, que corresponde a 84% dos bezerros nascidos. Os criadores adotam a relação touro:vaca de 1:25, o que resulta em uma subutilização de touros, tornando a reprodução natural antieconômica e subestimando a capacidade reprodutiva de touros competentes. A proporção touro:vaca é determinada por alguns fatores, como clima e nutrição, mas o principal fator determinante é a fertilidade do touro, estimada de forma mais precisa por meio do exame andrológico. O objetivo deste estudo foi construir um modelo de simulação como auxílio para a escolha da melhor relação touro:vaca de acordo com a combinação dos diversos fatores que determinam essa relação. É um modelo conceitual, empírico, estático e determinista que, por meio do processamento dos dados de entrada, simula a melhor relação touro:vaca. O modelo foi desenvolvido no software Vensim PLE 6.1. e descreve variáveis relacionadas a touros e vacas. Duas equações foram geradas para prever o potencial de acasalamento dos machos. Da mesma forma, de acordo com a condição reprodutiva das fêmeas, foram geradas equações para prever a taxa de ciclicidade delas. A soma dessas equações originou o que determina a relação touro:vaca de acordo com a condição reprodutiva das fêmeas. Esse modelo pode servir como um recurso para apoiar a decisão sobre a melhor relação touro:vaca e pode ser usado com várias combinações de características dos modelos. | The most used reproduction method in beef cattle in Brazil is natural breeding, which corresponds to 84% of calves born. Breeders adopt the bull:cow ratio of 1:25, which results in a sub utilization of bulls, making natural breeding antieconomic and underestimating the reproductive ability of competent bulls. The bull:cow ratio is determined by several factors, such as climate and nutrition, but the most determining factor is the fertility of the bull, estimated with more precision through breeding soundness examination of bulls. The aim of this study was to develop a simulation model as an aid to choose the best bull:cow ratio according to the combination of the many factors that determine this ratio. It is a conceptual, empiric, static, and determinist model which, through the processing of the input data, simulates the best BCR. Developed on the Vensim PLE 6.1 software, the model describes variables related to bulls and cows. Two equations were generated to predict the mating potential of males. In the same way, according to the reproductive status of females, equations were generated to predict the cyclicity rate of the cows. The sum of these equations originated the one that determines BCR according to the reproductive status of females. This model might serve as a tool to support decisions as to the best BCR and could be used with several combinations of models´ characteristics.

Síndrome Dolorosa Miofascial (SDM) é uma condição dolorosa relacionada aos pontos gatilhos miofasciais (PG) no músculo esquelético. Este trabalho tem como objetivo realizar uma revisão bibliográfica sobre a etiologia, fisiopatogenia, diagnóstico e tratamento na medicina veterinária. Foram utilizados sites de pesquisas Scientific Electronic Library, Pubmed e Medline. Os critérios de inclusão estabelecidos foram: ser escrito em inglês; no período de 1990 a 2018; ter as palavras chaves para busca: myofascial pain syndrome veterinary/dog/canine/cat/feline/ horse/equine, trigger points veterinary/dog/canine/cat/feline/horse/equine. Após a revisão observa-se que faltam estudos clínicos em medicina veterinária, sendo que os artigos encontrados se limitam à descrição, incidência e técnicas pontuais em cães e equinos, não sendo encontradas referencias em felinos. | Myofascial Pain Syndrome (MPS) a is a painful condition related to myofascial trigger points (TP) in skeletal muscle. The aim of this study was to perform a literature review on the etiology, pathophysiology, diagnosis and treatment of MPS in veterinary medicine. The research sites used for this purpose were: Scientific Electronic Library, PubMed and Medline. The inclusion criteria for the papers were: must be written in English; published between 1990 and 2018; include the following keywords: myofascial pain syndrome veterinary/dog/canine/cat/feline/horse/equine, trigger points veterinary/dog/canine/cat/feline/horse/equine. Through the review, it was observed that veterinary clinical studies are scarce, and the articles found lack information such as MPS description, incidence and specific treatment techniques in dogs and horses, and no studies in cats were found.

O objetivo deste estudo foi detectar a presença de anticorpos anti-Toxoplasma gondii em amostras de soro de 100 pardais (Passer domesticus Linnaeus, 1758) capturados na área urbana do município de Pelotas, Rio Grande do Sul, Brasil. Para a pesquisa de anticorpos anti-T. gondii foi utilizado o teste de aglutinação modificado (MAT) e foram consideradas positivas as amostras que apresentaram título > 5. Das 100 amostras de soro analisadas, 80 (80%) foram reagentes. Esses resultados demonstram que P. domesticus, por ser amplamente distribuído em todo país, pode desempenhar um papel importante na cadeia epidemiológica de T. gondii, podendo atuar como fonte de infecção para felinos domésticos e silvestres. | The objective of this study was to detect the presence of anti-Toxoplasma gondii antibodies in serum samples from 100 sparrows (Passer domesticus Linnaeus, 1758) that were caught in an urban area in southern Brazil. The modified agglutination test (MAT) was used to investigate anti-T. gondii antibodies and samples with a cut-off dilution > 5 were considered positive. Among the 100 serum samples analyzed, 80 (80%) were reactive. These results demonstrate that P. domesticus may play an important role in the epidemiological chain of T. gondii, since it is widely distributed throughout Brazil, and it may act as a source of infection to domestic, semi-domestic cats and to free-living wild felids.
