Bovinos, Diagnóstico, Leptospirose, ZoonoseResumo
A leptospirose é considerada uma zoonose bacteriana de importância para a saúde pública. É comum em áreas tropicais, especialmente em países em desenvolvimento com escassos recursos de saúde e saneamento. Este estudo avaliou a presença de Leptospira spp. em bovinos abatidos em frigorífico da região Centro-Oeste de São Paulo, Brasil, e identificou animais positivos tanto por sorologia quanto em análise molecular. Amostras biológicas de sangue, fígado e rins de 150 bovinos foram investigadas pela técnica de Teste de Aglutinação Microscópica (MAT) e Reação em Cadeia da Polimerase convencional (cPCR). Os resultados sorológicos mostraram que dos 150 animais, 71 (47,3%) foram reativos. Os resultados moleculares mostraram a presença de Leptospira spp. nos rins de 21 animais (14%), no fígado de 5 animais (3,3%), no fígado e rins em 2 animais (1,3%) e no sangue em 1 animal (0,7%). Esses resultados indicam um alerta sobre a saúde dos bovinos de corte devido à possibilidade desses animais serem fonte de infecção e a importância da característica ocupacional desta doença. Verificou-se também a importância de complementar as técnicas sorológicas e moleculares.
