E-mail: carolinespitz@yahoo.com.br A survey of anti-Leptospira spp. antibodies in animal from a horse breeding establishment located at the microregion of Itaguaí in the State of Rio de Janeiro was conducted. One hundred and thirty-nine blood samples from horses were collected and subjected to microscopic agglutination test (MAT). A total of 71.9% (100) of the samples had agglutinating antibodies against one or more serovars, with the predominance of Bratislava (29.2%), followed by Pomona (19.8%), Copenhagen (17.5%) and Hardjo prajitno (12.7%) Serovars. The reactivity rate between males (63.6%) and females (78.57%) showed no significant difference (p = 0.11). The group of animals younger than two years of age differed significantly from the others (p=0.0003). The results demonstrate that the animals of this micro-region have a high exposure to different Leptospira. serovars.
