Equino
Abstract in Portuguese
Em função da proximidade cada vez maior entre o cavalo e o homem, é de extrema importância ter conhecimentos das doenças que acometem os equinos, que por ventura, podem acometer seres humanos. Dentre muitas doenças, pode-se citar duas, que promovem grandes perdas econômicas aos rebanhos eqüinos, tanto no tratamento desses rebanhos, como com a morte dos mesmos, dificultando a importação e exportação de animais: a babesiose e a erliquiose (anaplasmose), que podem estar ou não associadas, acometendo um animal, concomitantemente. A presente pesquisa teve como objetivo investigar e diagnosticar doença concomitante babesiose (por Babesia equi ou Theileria equi) e Erliquiose (por Erliquia equi ou Anaplasma phagocytophilum), no estado de São Paulo, em rebanhos eqüinos, utilizando as técnicas de Nested PCR (Nested polymerase chain reaction reação em cadeia pela polimerase para diagnóstico de T. equi e A. phagocytophilum) e c-ELISA (competitive enzyme-linked immunosorbent assay para diagnóstico de T. equi) ou ELISA indireto (para diagnóstico de A. phagocytophilum) e comparar os resultados obtidos nas diferentes técnicas em 250 amostras de eqüino (sangue total e soro). Como resultado, obteve-se 38,4%, 46% e 36% de positividade, respectivamente, nos testes de pesquisa de hematozoário, c-ELISA e Nested PCR para Theileria equi e 0%, 3% e 0% de positividade, respectivamente, nos testes de pesquisa de hemoparasita, ELISA indireto e Nested PCR para Anaplasma phagocytophilum, não sendo observada a co-infecção de Babesiose e Anaplasmose no rebanho estudo

Abstract in English
Due to the increasing proximity between horse and man, it is of extreme importance to understand the diseases that affect horses which by chance may affect humans. Among many diseases, babesiosis and ehrlichiosis (anaplasmosis) promote high economic losses to horses herds in consequence of costs of treatment and also death, making it difficult to import and export animals: They can or not be linked affecting an animal at the same time. This study aimed to investigate and diagnose concomitant babesiosis (Babesia equi and Theileria equi) and ehrlichiosis (for ehrlichia equipment or Anaplasma phagocytophilum) in equine herds of the state of Sao Paulo, using the techniques of Nested PCR (Nested polymerase chain reaction for the diagnosis of T. equi and A. phagocytophilum) and c-ELISA (competitive enzyme-linked immunosorbent assay for diagnosis of T. equi) or ELISA (for diagnosis of A. phagocytophilum). Also to compare results obtained in these different techniques in 250 samples of horse (whole blood and serum). Results showed 38.4%, 46% and 36% positivity, respectively, in tests for the detection of Theileria equi through hematozoan, c-ELISA and Nested PCR and 0%, 3% and 0% positivity, respectively, in tests for the detection of Anaplasma phagocytophilum through blood parasites, indirect ELISA and Nested PCR. It was not observed co-infection Babesiosis and anaplasmosis in the herd study
