A serosurvey was conducted from A<\/jats:styled-content>ugust 2007 to M<\/jats:styled-content>arch 2009 in five herds from R<\/jats:styled-content>io de J<\/jats:styled-content>aneiro, B<\/jats:styled-content>razil, with high rates of reproductive failure, as early embryonic death (>12%), abortion (>12%) and perinatal death. Detailed information about the losses was obtained from practitioner. A total of 338 recipient mares were tested by microscopic agglutination test, and 226 (66.9%) were seroreactive, mainly against serovars B<\/jats:styled-content>ratislava and C<\/jats:styled-content>openhageni. Seroreactivity could be associated to reproductive failure (p\u00a0<\u00a00.001), and it was demonstrated that a seroreactive mare is 1.8 times more likely (relative risk \u2013 RR<\/jats:styled-content>) to present reproductive failure than a seronegative one, particularly in relation to early embryonic death (p\u00a0<\u00a00.0001; RR<\/jats:styled-content> 8.4) but also to abortions (p\u00a0<\u00a00.0001; RR<\/jats:styled-content> 3.5), and to perinatal death (p\u00a0<\u00a00.05; RR<\/jats:styled-content> 7.3).
