Serum prevalence of anti-Trypanosoma vivax antibodies in cattle in Tapira-MG, Brazil / Soroprevalência de anticorpos anti-Trypanosoma vivaxem bovinos em Tapira-MG, Brasil

Trypanosoma vivax is considered the most important pathogenic Trypanosoma for cattle and causes great damage to the dairy and beef cattle industries. This study aimed to evaluate the prevalence of anti-T. vivax antibodies in dairy cattle from the municipality of Tapira, located in the Alto Paranaíba region, Minas Gerais, Brazil. The 74 blood serum samples from dairy cattle were analyzed using an indirect immunofluorescence reaction. The seroprevalence was 82.4 % (61/74), and the highest incidence observed can be correlated with the transit of untested animals, the presence of vectors, and needle sharing by owners. The data allowed defining Tapira as an area of expansion of T. vivax epizootic infections in the state of Minas Gerais.

O Trypanosoma vivax é considerado o mais importante trypanosoma patogênico para bovinos e causa grandes prejuízos na pecuária de corte e leite. Este estudo teve como objetivo avaliar a prevalência anticorpos de anti-Trypanosoma vivax em bovinos leiteiros do município de Tapira, localizado na região do Alto Paranaíba, Minas Gerais, Brasil. As 74 amostras de soro sanguíneo de bovinos leiteiros foram analisadas por meio de reação de imunofluorescência indireta. A soroprevalência foi de 82,4% (61/74), que pode estar relacionada ao trânsito de animais não testados, presença de vetores e compartilhamento de agulhas pelos proprietários. Os dados permitiram definir Tapira como uma área de expansão das infecções epizoóticas por Trypanosoma vivax no estado de Minas Gerais.

Infecção verdadeira por Capillaria hepatica em cão / True infection by Capillaria hepatica in a dog

Background: Capillaria hepatica is a nematode, zoonotic, with worldwide distribution. The main hosts are rodents, nevertheless other mammals can be affected. Although the parasite has high affinity for the liver, it rarely causes a hepaticdisease in domestic animals and humans. The diagnosis is difficult and usually a biopsy is required. The treatment is difficult and is based in anti-helminthic and corticoid, but prevention is the best strategy against the disease. The aim of thepresent report is to describe a case of hepatic capillariosis in a dog approaching the clinical signs, diagnosis and therapeutic.Case: A 12-year-old Brazilian Terrier bitch, with a history of visit to the farm and regular hunting of rats, frogs, birds andother wild animals, was attended with hyporexia and apathy. At the physical exam the dog presented elevation of rectaltemperature, intense jaundice and abdominal pain. In the biochemical exams was noticed a slight increase in globulins anda sharp increase in alkaline phosphatase (AP), total, direct and indirect bilirubin, suggesting a liver injury. In the ultrasonographic exam, hepatomegaly with dispersed hyperechoic areas were observed, suggesting hepatic steatosis. The patientwas treated with ursodesoxicolic acid and S-adenosil metionin for 30 consecutive days, showing a clinic improvement.Two months after the end of the treatment the animal worsened, showing jaundice, ascites, motor incoordination, weakness, difficulty in food and water ingestion and changes in the mental state. In the complete blood count was observed amacrocytic hypochromic regenerative anemia, leukocytosis with neutrophilia and monocytosis and thrombocytopenia.In biochemical exams was detected decrease in creatinine and albumin and increase in alanine aminotransferase and AP,suggesting hepatopathy by biliary obstruction. There were performed exams for leishmania and ehrlichiosis that testednegative. In the ultrasonographic exam it...

Effectiveness of tobramycin and ciprofloxacin against bacterial isolates in canine otitis externa in Uberaba, Minas Gerais / Eficácia de tobramicina e ciprofloxacina contra isolados bacterianos de otite externa canina em Uberaba, Minas Gerais

Canine otitis externa is a common and recurrent disease in domestic dogs. Although not being life threatening, it can result in the overuse of antibiotics, increased bacterial resistance and reduction of options for treatment. This study aimed to determine: the principal characteristics (age, race, and gender) of dogs affected by otitis externa; the most frequently bacteria identified as being associated with it and their antimicrobial resistance profiles. A total of 221 bacterial isolates were identified by morphological staining and biochemical processes and tested against eleven antibiotics. Among the 148 dogs diagnosed with otitis externa, 51.4% (76/148) were males and 48.6% (72/148) females. The cases were detected mainly in dogs with age above 7 years (54.7%; 81/148. Among the races examined, poodles were the most numerous (14.84%; 22/148). The most common bacteria found were: coagulase-negative Staphylococcus (StCN), 33.9% (75/221); coagulase-positive Staphylococcus (StCP), 19% (42/221); Proteus spp., 17.2% (38/221) and Pseudomonas aeruginosa, 9.5% (21/221). Simultaneous resistance to more than three classes of antimicrobials were most frequently detected in P. aeruginosa (61.9%; 13/21) and Proteus spp (39.47%; 15/38). According to data obtained from this study, two veterinary medications found to be most effective for topical treatment were tobramycin and ciprofloxacin.

Estudo retrospectivo de cães positivos para cinomose, em ensaio imunocromatográfico, atendidos no hospital veterinário de Uberaba - MG

A Cinomose canina é causada por um vírus do gênero Morbillivirus pertencente à família Paramyxoviridae. O tropismo viral pelos leucócitos pode levar à leucopenia com linfopenia, seguida de imunossupressão. Além disso, também pode ser observada trombocitopenia imunomediada. A detecção de antígenos virais, em swabs das conjuntivas de cães suspeitos de estarem infectados com cinomose, pode ser feita por meio da técnica de imunocromatografia. A infecção com o vírus da cinomose pode ser prevenida através da vacinação dos animais. A determinação da associação entre a infecção pelo Morbillivirus e alterações hematológicas e/ou bioquímicas em cães naturalmente infectados, pode auxiliar no acompanhamento do animal enfermo. Neste estudo retrospectivo, foram analisados os dados hematológicos e bioquímicos de 149 cães, de diferentes raças e idades, atendidos no Hospital Veterinário de Uberaba, Minas Gerais, no período entre os anos de 2008 a 2012, todos com diagnóstico positivo para antígenos virais de cinomose. 18,79% foram vacinados; 45,63% não eram vacinados e 35,57% estavam com vacinação atrasada. Em relação ás alterações hematológicas, obteve-se em maior quantidade: 48,32% anemia; 26,10% desidratação e 50,33% trompocitopenia. Já nas alterações de leucometria, observou-se em maior quantidade: 42,21% com valores normais de leucócitos; 57,71% linfopenia. A maioria dos casos positivos ocorreram no período seco do ano.

The Canine Distemper is caused by a virus of the genus Morbillivirus belonging to the family Paramyxoviridae. The viral tropism by leukocytes can lead to leukopenia with lymphopenia, followed by immunosuppression. It also can be seen immunomediated thrombocytopenia. The detection of viral antigens in the conjunctival swabs of dogs suspected of being infected with canine distemper, can be made by immunochromatography technique. The infection with canine distemper virus may be prevented by vaccinating the animals. The determination of the association between infection and Morbillivirus hematological and / or biochemical changes in naturally infected dogs, can assist in monitoring the animal sick. In this retrospective study, we analyzed the data of 149 hematological and biochemical dogs of different breeds and ages met at the Veterinary Hospital of Uberaba, Minas Gerais, in the period between the years 2008 to 2012, all with positive diagnosis of distemper viral antigens . 18.79% were vaccinated; 45.63% were not vaccinated and were 35.57% with vaccination records. Regarding hematological ace, was obtained in greater quantity: 48.32% anemia, dehydration 26.10% and 50.33% trompocitopenia. Have changes in leukocyte count was observed in greater amounts: 42.21% with normal leukocytes; 57.71% lymphopenia. Most of the positive cases occurred in the dry season.
