Achados gastroscópicos em eqüinos adultos assintomáticos Gastroscopic findings in horses without clinical signs

Avaliaram-se pela gastroscopia 21 eqüinos adultos sem manifestações clínicas. A prevalência de úlceras gástricas foi alta, 47,6%, principalmente ao longo do margo plicatus, embora de baixa gravidade. Gastrite leve ou moderada da mucosa glandular constituiu um achado comum em eqüinos adultos assintomáticos submetidos a jejum para exame gastroscópico. A ocorrência de Habronema sp. foi alta, 28,6%, o que resultou em gastrite catarral crônica.<br>Twenty one adult horses without clinical signs were used for gastroscopic study. High prevalence (47.6%) of gastric ulceration was observed, especially adjacent to the margo plicatus, although with low severity. Mild or moderate gastritis of the glandular mucosa was an usual finding in these horses submited to fasting for gastroscopic examination. The occurrence of Habronema sp. was high (28.6%), and caused chronic catarrhal gastritis

Mammary botryomycosis: two concomitant cases in mares: case report

ABSTRACT Mammary disorders in mares are rare and usually only one animal per paddock is affected. In this report, two mares with 7 and 9 years old, were concomitantly diagnosis of chronic pyogranulomatous mastitis, associated with the Splendore-Hoeppli reaction, indicative of botryomycosis a rare, chronic suppurative disease with microabscess formation, characterized by in vivo formation of eosinophilic materials around microorganisms or biologically inert material. Various bacteria can cause botryomycosis in horses, and the most frequently isolated one is Staphylococcus sp., particularly S. aureus. This report confirms the role of Staphylococcus sp.; however, specifically S. hyicus and S. cohnii that prior to the current report, had not been associated with cases of botryomycosis

Electrocardiographic parameters in clinically healthy Thoroughbred horses

Determinaram-se as características eletrocardiográficas de amplitude, duração, ritmo e eixo cardíaco no plano frontal de potros, sobreanos e éguas prenhes clinicamente normais, da raça Puro Sangue Inglês. Estudaram-se 50 potros e 50 sobreanos, machos e fêmeas, e 11 éguas prenhes. Concluiu-se que a freqüência cardíaca diminui com a idade e que nos potros e sobreanos as características apresentaram valores intermediários entre os valores padrão de neonatos e adultos. Nos sobreanos eles estão mais próximos dos de referência para adultos. Nas éguas em gestação a única diferença observada com o padrão foi o leve desvio para a direita do eixo cardíaco.The determination of the electrocardiographic parameters of amplitude, duration, rhythm and electrical axis in the frontal plane from clinically healthy Thoroughbred foals, yearlings and pregnant mares was performed. Fifty foals and 50 yearlings, males and females, and 11 pregnant mares were used. It was concluded that the heart rate decreases with age and that foals and yearlings had intermediate values between reference values of neonates and adults. In yearlings, these values were more similar to the reference values of adults. In pregnant mares, the only difference observed when compared to reference values was the slight right displacement of the electrical axis
