RESUMO
Foi investigada a prevalência de anticorpos anti-Leptospira spp em 2.109 vacas provenientes de 86 rebanhos do município de Monte Negro, Rondônia, Brasil. As amostras de soro sanguíneo foram avaliadas pelo Teste de Aglutinação Microscópica frente a 24 sorovares de leptospira. Títulos =100 para um ou mais sorovares foram detectados em 1.114 vacas (52,8%) de 82 (95,3%) rebanhos. A prevalência ajustada para o município de Monte Negro foi de 53,9% (I.C. 95%; 49-58,7%). Os sorovares mais prevalentes foram Hardjo (14,5%), Wolffi (12,3%), Shermani (10,8%), Patoc (7,9%) e Hebdomadis (6.1%). Outros sorovares mundialmente relatados como Bratislava, Pomona e Grippotyphosa foram pouco detectados.
ABSTRACT
The prevalence of anti-Leptospira spp antibodies was investigated in 2,109 female cattle from 86 herds of Monte Negro municipality, Rondônia, Brazil. Sera samples were evaluated by Microscopic Agglutination Test against 24 leptospira serovars. Titers =100 for at least one of 24 leptospira serovars were detected in 1,114 cows (52.8%) from 82 (95.3%) herds. The adjusted overall prevalence for Monte Negro municipality was 53.9% (49-58.7%; CI 95%). The most prevalent serovars were Hardjo (14.5%), Wolffi (12.3%), Shermani (10.8%), Patoc (7.9%), and Hebdomadis (6.1%). Other serovars worldwidely reported like Bratislava, Pomona and Grippotyphosa were detected in low levels.
