O emprego de dietas para cães contendo carne crua tem sido uma prática popular frequente. Estas, quando contaminadas por Salmonella, podem oferecer risco para a saúde dos animais e dos seres humanos. Este trabalho é uma revisão sistemática da literatura efetuada para avaliar a frequência de dietas para cães que continham carne crua contaminada por Salmonella, e se os cães que as consumiam eliminariam a bactéria em suas fezes. A pesquisa foi realizada em duas bases de dados, Web of Knowledge e PubMed, durante janeiro de 2015. Participaram da pesquisa trabalhos sobre dietas para cães contendo alimentos crus e seu consumo; treze artigos foram selecionados. Em 11 trabalhos foram conduzidas análises microbiológicas para Salmonella nas dietas contendo carne crua, sendo que em quatro desses estudos também foi analisada a presença da bactéria nas fezes dos animais. Em 679 dietas contendo carne crua, 141 delas (20,76%) estavam contaminadas, sendo o sorotipo mais encontrado foi Salmonnela Typhimurium (24,60% do total). Dos estudos que relataram a eliminação da bactéria após o consumo de dietas contendo carne crua, um total de 141 amostras fecais foram analisadas, das quais 73 (51,77%) estavam contaminadas, e o sorotipo mais encontrado foi Salmonella Newport (72,60% do total). Os resultados obtidos permitem afirmar que os proprietários dos cães alimentados por dietas (caseiras ou comerciais) a base de carne crua contaminada estão expostos ao risco de infecção por Salmonella tanto pela manipulação de alimentos como pelas fezes dos animais. | Feeding dogs raw meat diets is an increasingly popular trend, and when contaminated with Salmonella they may present a risk to the health of both animals and humans. The present investigation is a systematic review of literature to assess the frequency of raw meat diets for dogs contaminated with Salmonella and whether dogs consuming these diets can eliminate it in their faeces. A search was made using two databases: “Web of Knowledge” and “PubMed” in January 2015. Only studies related to raw food diets and consumption by dogs were included. Thirteen articles were selected after refining the search. In 11 studies microbiological analysis was conducted for Salmonella in diets containing raw meat, so that in four of these studies Salmonella in the faeces was also analysed. In the analysis of 679 raw meat diets 141 diets (20.76%) were contaminated with Salmonella, in which the serotype most commonly found was S. Typhimurium (24.60%). Of the studies that reported the number of dogs that eliminated Salmonella in faeces after consumption of diets containing raw meat, 141 faecal samples were analysed, of which 73 (51.77%) were contaminated with Salmonella and the serotype most commonly found was S. Newport (72.60%). The available data suggest that the owners who feed their animals with diets containing contaminated raw meat, either commercial or homemade, are exposed to risk of Salmonella contamination, either by the manipulation of food or by handling the dog’s stool.

No Brasil, os dípteros do gênero Lutzomyia são os principais vetores da leishmaniose para humanos e animais. No entanto, tem sido constatado que outras espécies de invertebrados hematófagos, como carrapatos, pulgas e mutucas, também podem ser vetores desse protozoário. Este trabalho, realizado em uma área endêmica de leishmaniose visceral, é a primeira descrição da presença de Leishmania spp. em mosquitos da espécie A. aegypti. Dois mosquitos A. aegypti foram capturados no local onde estava isolado um cão polissintomático acometido por leishmaniose visceral, confirmada pela demonstração do parasita em biópsias de órgãos e por resultado positivo na prova de PCR para Leishmania spp. Um dos mosquitos estava sugando o sangue do cão e o outro estava livre no ambiente. O mosquito ingurgitado com o sangue do animal foi esmagado entre duas lâminas de microscopia e o outro foi processado por meio da reação em cadeia pela polimerase (PCR) aplicada à pesquisa do ADN de Leishmania spp. Ao exame microscópico do esfregaço preparado com o mosquito que estava parasitando o cão foram observadas formas amastigotas de Leishmania spp., bem como formas flageladas de outra espécie de protozoário. No outro inseto foi detectada amplificação de ADN do gênero Leishmania. Esta constatação reforça o papel dos cães como fontes de infecção de Leishmania spp. até mesmo para outras espécies de vetores potenciais. | In Brazil dipters of the Lutzomyia genus are the main vectors of leishmaniasis for humans and animals. However, other hematophagous insects such as ticks, fleas, and horse flies may also be considered potential vectors of this protozoon. This paper, regarding an endemic area for visceral leishmaniasis, is the the first description of the Leishmania spp. presence in Aedes aegypti mosquitoes. Two A. aegypti mosquitoes were captured: one of them was feeding on a polysymptomatic dog with leishmaniasis, confirmed by parasitic demonstration and positive PCR for Leishmania spp., and the other was collected in the environment where the dog was isolated. The mosquito engorged with dog’s blood was crushed between two microscopic slides and the other one was processed by the polymerase chain reaction assay (PCR) searching for the presence of Leishmania spp. DNA. Amastigote forms of Leishmania sp, were observed in the smear prepared from one mosquito by microscopic examination, as well as other protozoa’s flagellated forms. In the other insect it was observed Leishmania DNA amplification. This observation reinforces the role of dogs as sources of infection of Leishmania spp. even to other potential vector species.

O hemangiossarcoma (HSA) é uma neoplasia maligna originada no endotélio vascular, com alto poder metastático e comumente descrito no baço, fígado e átrio direito. Assim, o objetivo deste trabalho é relatar a ocorrência do HSA na base do átrio esquerdo de um cão, macho, idoso, da raça Lhasa Apso, atendido apresentando cianose, posição ortopneica e tosse. No exame físico foi observado presença de crepitação em lobos pulmonares e sopro em foco de mitral e tricúspide grau IV\VI. Foi realizada terapia emergencial preconizada até a melhora clínica do animal, e após a ecocardiografia confirmou-se a degeneração valvular mitral e tricúspide, bem como a presença de uma imagem irregular, de ecogenicidade mista, extracardíaca e imóvel na base do átrio esquerdo, medindo 2,9 x 1,44 cm de diâmetro. A terapia clínica instituída estabilizou o quadro clínico por 128 dias, havendo recidiva do edema pulmonar e efusão pleural hemorrágica grave, com os proprietários optando pela eutanásia do animal e a necropsia, confirmando o diagnóstico definitivo do HSA extracardíaco na base do átrio esquerdo. | Hemangiosarcoma (HSA) is a malignant neoplasm originating from the vascular endothelium, with high metastatic power and commonly described in the spleen, liver, and right atrium. Thus, the objective of the present study is to report the occurrence of HSA at the base of the left atrium of a male, elderly, Lhasa Apso dog, treated with cyanosis, orthopedic position, cough. In the physical examination, the presence of crackling was observed in pulmonary lobes, murmur in focus of mitral and tricuspid grade IV\VI. The recommended emergency therapy was performed until the clinical improvement of the animal. After echocardiography, mitral and tricuspid valvular degeneration was confirmed, as well as the presence of an irregular, mixed echocardiogram, extra-cardiac, immobile at the base of the left atrium, measuring 2.9 x 1.44 cm in diameter. The clinical therapy established stabilized the clinical picture for 128 days, with recurrence of pulmonary edema and severe hemorrhagic pleural effusion, with the owners opting for euthanasia of the animal and necropsy confirming the definitive diagnosis of extrahepatic SAH at the base of the left atrium.

Diabetes Mellitus é uma desordem crônica que resulta em hiperglicemia pela deficiência absoluta ou relativa de insulina, que gera complicações que podem levar à morte. O sucesso do tratamento do cão diabético depende da aplicação de insulina e do adequado manejo nutricional. Estudos que avaliaram aspectos nutricionais de cães diabéticos focavam na fibra dietética como o principal fator controlador da glicemia, porém novas pesquisas apontam o amido como principal responsável pelas respostas glicêmicas pós-prandiais e atribuem importante papel ao escore de condição corporal e ao manejo alimentar no adequado controle glicêmico de cães diabéticos. O objetivo deste trabalho é revisar os principais aspectos da nutrição de cães diabéticos para o melhor controle da doença. | Diabetes mellitus is a chronic disorder that results in hyperglycemia by absolute or relative insulin deficiency, sometimes leading to fatal complications. The successful treatment of diabetic dogs depends on nutritional management and insulin applications. Studies evaluating the nutrition of diabetic dogs focused on fiber as the main factor in glycemic control; however, new research describes the role of starch as key in postprandial glycemic fluctuation, also attributing a central role for body condition scores and feed management in the adequate glycemic control of diabetic dogs. The aim of this paper is to review nutritional aspects to better control diabetes in dogs.

O potencial zoonótico de bactérias multirresistentes é uma preocupação global e os animais de companhia têm sido implicados na disseminação de bactérias resistentes; assim, é importante a vigilância, pois já existem relatos de transmissão destas bactérias do cão para o homem e vice-versa. Um cão, sem raça definida e de cinco anos de idade, foi atendido na cidade de Botucatu, São Paulo, Brasil, apresentando urolitíase obstrutiva de estruvita recorrente há um ano e meio. Na urocultura do animal foi isolada uma estirpe de Staphylococcus spp. multirresistente; o tratamento com vancomicina possibilitou acura clínica. A estirpe de Staphylococcus spp. isolada foi identificada molecularmente como S. pseudintermedius e nela foi identificada a presença do gene mecA, o principal responsável por S. pseuidintermedius resistente à meticilina (MRSP), e que é frequentemente resistente à múltiplos antimicrobianos. As hipóteses para este caso clínico são a transmissão do homem para o animal, pois o tutor era um médico intensivista, ou que a própria bactéria fazia parte da microbiota do animal e, devido a outros fatores como estresse e doença urinária obstrutiva, abriu-se uma porta de entrada para a infecção pelo S. pseudintermedius. Mais estudos são necessários para a elucidação da transmissão de bactérias multirresistentes entre animais de companhia e o ser humano. | The zoonotic potential of multidrug resistant (MDR) bacteria is a worldwide concern and companion animals have been implicated in the spread of resistant bacteria. Therefore, surveillance is important, as there are reports of transmission of these bacteria from dog to men, as well as from men to dog. A 5-year-old mixed-breed male dog was admitted with obstructive struvite urolithiasis relapsing for over 18 months, in Botucatu, in the state of São Paulo, Brazil. The strain, biochemically identified as Staphylococcus spp., was MDR and was treated off-label with vancomycin, which resulted in clinical cure. The strain was molecularly identified as Staphylococcus pseudintermedius and the mecA gene was identified. This is the main gene responsible for methicillin-resistant S. pseudintermedius (MRSP), which is often resistant to multiple antimicrobials. The hypotheses for this clinical case are the transmission from man to animal, since the tutor was an intensivist doctor, or the bacterium itself could be part of the animal’s microbiota and due to other factors, such as stress or obstructive urinary disease, opened a doorway to infection by S. pseudintermedius. Further studies should elucidate the transmission of MDR bacteria between human and pets.

A celulite juvenil (CJ) é uma doença vesiculopustular incomum que acomete cães principalmente na faixa etária inferior aos quatro meses. Este trabalho analisou o perfil epidemiológico, clínico e terapêutico da CJ em cães a partir da casuística do Hospital Veterinário da Universidade Federal Rural do Semi-Árido, referente aos anos de 2009 a 2016. Cinco casos foram diagnosticados, incluindo quatro cães (80%), sem raça definida e com idade média de dois meses e 22 dias, e um da raça Rottweiler (20%) com 38 meses de idade. O período evolutivo médio das lesões foi de 16 dias e os principais sinais clínicos observados foram edema, pápulas, pústulas e secreção ótica bilateral. O diagnóstico foi confirmado por citologia (80%) e histopatologia (20%). Em todos os animais, o tratamento consistiu de cefalexina, administrada por 30 dias, e prednisolona, por três semanas. A terapia otológica tópica foi incluída quando necessária. Em quatro casos o desfecho clínico foi favorável. A CJ é uma dermatopatia rara que merece atenção especial dos clínicos veterinários. | Juvenile cellulitis (JC) is an uncommon vesiculopustular disease that affects dogs, especially those under four months of age. The aim of the present study was to characterize the epidemiological, clinical, and therapeutic profile of JC based on clinical records of canine patients treated at the Veterinary Hospital of the Universidade Federal Rural do Semi-Árido, between the years 2009 and 2016. A total of five cases were diagnosed. Four dogs presented at an average age of two months and 22 days and were crossbred; the other dog was a rottweiler aged 38 weeks. The average time of evolution of the disease was 16 days, and the main clinical signs were edema, papules, pustules, and bilateral ocular discharge. The diagnosis was confirmed by cytology in four animals and by histopathology in only one patient. For all dogs, the treatment was based on cephalexin, administered for 30 days, and prednisolone for three weeks. Otological therapy was included when necessary. Four cases had a favorable outcome. JC is a rare dermatopathy that deserves special attention from veterinary practitioners.

É prática corrente em ambulatórios, consultórios, clínicas e hospitais veterinários paulistas, por não dizer brasileiros, a prescrição de ativos com ação vermicida, no senso lato, sem o embasamento do, hoje até prosaico, exame coproparasitológico. É sabido há muito que todo e qualquer fármaco não é inócuo e pode potencialmente acarretar agravos à saúde, e dentre estes incluem-se os ativos destinados à erradicação de parasitos entéricos. Decidiu-se assim por se relatar um caso clínico de paniculite farmacodérmica decorrente de vermifugação, bem como situar a real ocorrência de endoparasitas em pacientes, caninos e felinos, trazidos para atendimento ambulatorial no HOVET-USP. | Outpatient clinics, clinics, and veterinary hospitals in the state of São Paulo and other Brazilian states commonly prescribe broad-spectrum vermicidal agents. The prescriptions are not based on coproparasitological examination results and drugs, including those used for the elimination of enteric parasites, are not innocuous and can potentially cause health hazards. Therefore, we report a clinical case of drug-induced panniculitis caused by deworming and show the actual occurrence of endoparasites in canine and feline outpatients at HOVET-USP.

Introduction: The study was conducted to investigate the prevalence and genetic diversity of Chlamydia spp. in poultry in Poland and estimate possible transmission to humans. Material and Methods: Molecular diagnostic methods followed by sequencing and strain isolation were used on cloacal/faecal swabs collected from 182 apparently healthy poultry flocks including chickens, turkeys, ducks, and geese. Serum samples obtained from people exposed (study group) and non-exposed (control group) to birds were tested by complement fixation test to acquire data on Chlamydia spp. antibody level. Results: Overall, 15.9% of the tested flocks were Chlamydiaceae-positive and three Chlamydia spp. were identified. Predominant chlamydial agent found was C. gallinacea occurring in 65.5% of all positive poultry flocks and in 73.0% of positive chicken flocks. The sequences from four chicken flocks were assigned to C. abortus, whereas C. psittaci was confirmed in one duck and one goose flock. The analysis of ompA variable domains revealed at least nine genetic variants of C. gallinacea. Chlamydial antibodies were detected in 19.2% of human serum samples in the study group in comparison with 10.8% in the controls. Conclusion: The obtained results confirm that chlamydiae are common among chicken flocks in Poland with C. gallinacea as a dominant species. Moreover, the presence of C. abortus in chickens is reported here for the first time. Further investigation should focus on possible zoonotic transmission of C. gallinacea and C. abortus as well as potential pathogenic effects on birds’ health and poultry production.

Introduction: Infectious bursal disease virus (IBDV) is a causative agent of immunosuppressive disorder resulting in significant losses to the world poultry industry. This study describes the molecular characterisation of an atypical IBDV from a field outbreak that occurred in vaccinated chicken flocks in Latvia in 2011.Material and Methods: Ten bursae of Fabricius from each flock were collected for laboratory examination. Virus isolation was performed in embryonated eggs and CEF culture. The RT-PCR aimed at hypervariable domain of VP2 gene combined with sequencing was performed for detection and identification of IBDV.Results: The molecular examinations confirmed the IBDV infection. The analysis of the amino acid sequence revealed that the strain possessed four amino acids at VP2 protein (222A, 256I, 294I, and 299S), indicating a genetic relatedness to a very virulent IBDV. However, some unique or rare amino acid substitutions (219L, 220F, 254D, 279N, and 280T) were also detected.Conclusion: The obtained results demonstrate the occurrence of IBDV with a high mutation rate within the hypervariable domain of VP2 peptide, and highlight the necessity of implementation of IBDV surveillance in Eastern European poultry industry to determine whether this strain is an exception or a new wave of IBDV with new genetic features emerged in the field.

Introduction: A model of fatty liver in postpartum sheep was established to measure blood paraoxonase 1 (PON1) and other biochemical indicators, which were used to predict fatty liver in sheep. Material and Methods: Sheep were assigned into two experimental groups: a fatty liver group (T, n = 10) and a healthy control group (C, n = 5). PON1 enzyme activity towards paraoxon as a substrate was quantified spectrophotometrically. The results were analysed by t-test and pearson correlation coefficient. Disease was predicted by binary logistic analysis, and diagnostic thresholds were determined by receiver operatingcharacteristic (ROC) analysis. Results: The activity of serum PON1 in group T was significantly decreased (P < 0.05) when compared with C group, and liver lipid content and the levels of serum BHBA, NEFA, and TG were significantly increased (P < 0.05). Thresholds were lower than 74.0 U/mL for PON1, higher than 0.97 mmol/L for β-hydroxybutyrate, higher than 1.29 mmol/L for non-esterified fatty acids, higher than 0.24 mmol/L for triglycerides, and lower than 71.35 g/L for total protein. Conclusion: This study verified that PON1, BHBA, NEFA, TG, and TP could be used to predict the risk of fatty liver in sheep.
