| A adenite equina, também conhecida como garrotilho, é uma enfermidade bacteriana contagiosa, causada por Streptococcus equi, subsp. equi, bactéria β hemolítica do grupo C de Lancefield, que afeta o trato respiratório anterior de equinos de todas as idades, com maior prevalência entre um e cinco anos de idade. Caracteriza-se por produzir secreção mucopurulenta das vias aéreas anteriores e linfadenite dos gânglios retrofaríngeos e submandibulares com formação de abscessos. Fatores de virulência de S. equi, subsp. equi, incluem cápsula de ácido hialurônico, hialuronidase, estreptolisina O, estreptoquinase, receptores para Fc de IgG, peptidoglicano e proteína M. Dentre esses fatores, a proteína M tem especial importância por ser de membrana com propriedades... |

| ABSTRACT: The aims of this study were: 1) to compare the tape weight and associated weight-estimation formula to evaluate weight gain in pregnant mares, and 2) to develop a mathematical model to estimate the weight of pregnant mares using body measurements. Thirty-four criollo-type mares were evaluated every two weeks during the middle and late pregnancy. The mares were weighed on a livestock scale, and we estimated body weight using tape weights and an associated body-weight estimation formula. Also, heart-girth circumference (heartgirth) and abdominal circumference were measured; the latter at the 12th intercostal space (12th ICS) and 18th rib (18th Rib), to use in a mathematical model to estimate the weight of pregnant mares. Observations were divided... |

| Foram avaliados fatores de risco associados à ocorrência de doenças respiratórias em 349 potros Puro Sangue Inglês (PSI) monitorados do nascimento ao sexto mês de vida na região de Bagé, Rio Grande do Sul (RS), Brasil. A partir da avaliação clínica e laboratorial pôde-se registrar a frequência de 9,5% (33) casos respiratórios, com mortalidade de 0,57% (2). A ocorrência de casos foi mais elevada nos meses de verão, e potros com idade entre quatro e seis meses foram mais suscetíveis (P<0,001). O desenvolvimento de doenças foi influenciado (P<0,001) pelo sistema de criação e pelas práticas de manejo, os quais aumentaram o potencial de contaminação do ambiente. Na avaliação microbiológica, a maior frequência de isolados foi de Streptococcus equi (57%),... |

| Horse Strangles appears frequently in animals vaccinated with commercial bacterins in Rio Grande do Sul, Brazil. Aiming to know the antigenic relationships of strains recovered from sick animals among them and with two vaccines profusely used in the state, bilateral cross reactivity indices (CRI) were estimated. In addition, the immunogenicity of vaccines prepared with field isolates and commercial vaccines was tested in mice. Antibody titers were measured by ELISA and expressed as seroconversions. Thirteen strains of Streptococcus equi subsp. equi, nine classified biochemically as typical and other four as atypical strains, were recovered from 35 sick horses belonging to 10 herds of Rio Grande do Sul, Brazil. The strains recovered from sick horses showed... |

| ABSTRACT: The aim of this study was to evaluate the effects of Allopurinol in foals born from mares with placentitis. Twenty foals were assigned into two groups: Healthy foals (n=10), born from healthy mares and Placentitis foals (n=10), born from mares with placentitis. Five foals from each group were randomly assigned to a treatment or control group. Treatment groups received Allopurinol (40mg kg-1 orally six hours after birth). Blood samples were collected for estimation of hematological variables and serum concentration of calcium, chloride, creatinine, phosphorus, glucose, lactate and magnesium. Placentitis foals presented leukopenia and neutropenia when compared with Healthy foals, at birth. The white blood cell (WBC) count was lower in the... |

| Paracoccidioides brasiliensis is the etiological agent of the major systemic mycosis in Brazil, called paracoccidioidomycosis. Although the Rio Grande do Sul is considered an endemic area of the disease, there are few studies on the ecology of P. brasiliensis in the state. Therefore, this study aimed to evaluate the infection of P. brasiliensis in horses from the mesoregion of Southwest Riograndense, using these animals as sentinels. Serological techniques, such as double immunodiffusion in agar gel (AGID) and indirect ELISA, were performed to detect the anti-gp43 P. brasiliensis antibody in horses from five different farms in the region of Bagé, RS, Brazil. Serology was performed in 200 Pure Blood English horses up to two years of age that were born and... |
