Risk Factors Associated With Seroreactivity Against Leptospira sp. in Horses From Brazilian Amazon (original) (raw)

This study investigated the risk factors associated with seroreactivity to Leptospira sp. in horses from Brazilian Amazon. Blood samples were collected and Microscopic agglutination test (MAT) was performed; and univariate and multivariate analysis was conducted for association with risk factors. General seroprevalence was 32.7% and the most prevalent serogroup observed was Sejroe (5.9%). Seroreactivity was associated with age, sex, activity (work, leisure or both), feed supplementation, trash accumulation and presence of felines. Epidemiology of leptospirosis remains poorly understood in Amazon region, particularly in livestock, requiring more studies in order to improve control and prevention measures.
