The objective of this study was to determine the frequency and factors associated with the occurrence of seropositivity for Leptospira spp. in goat herds in the state of Sergipe, Brazil, on the basis of the analysis of 675 samples collected from 41 properties in 2013-2014. Analysis of anti-Leptospira spp. antibodies revealed that 25.74% goats (194) were seropositive and that 90.24% (37) of the properties had at least one infected goat. The most prevalent serogroup was Icterohaemorrhagiae (85.57%); although, the study animals were reactive to other serogroups: Australis (5.15%), Pomona (3.61%), Sejroe (3.09%), and Pyrogenes (2.58%) had titers [less than or equal to]400 in 96.91% of cases. The origin of the water source [still water source (OR=3.86)] was associated with seropositivity. Results reflected the importance of adopting appropriate management practices for herds in Sergipe. Key words: water source, leptospirosis, serogroup, Icterohaemorrhagiae, test microscopic agglutination test. O objetivo deste estudo foi determinar a frequencia e os fatores associados a soropositividade para Leptospira spp. em caprinos do Estado de Sergipe, Nordeste do Brasil, utilizando 675 animais de 41 propriedades no periodo de 2013 e 2014. A frequencia de positividade entre os animais foi de 25,74% (194), e em 90,24% (37) das propriedades houve pelo menos um animal soropositivo. O sorogrupo reagente predominante foi o Icterohaemorrhagiae (85,57%), com presenga tambem de animais reagentes para Australis (5, 15%), Pomona (3, 61%), Sejroe (3, 09%) e Pyrogenes (2, 58%) com titulos [less than or equal to]400 em 96, 91% dos casos. A origem da agua fornecida (agua parada) (OR=3,86) foi o fator associado a presenga de caprinos positivos. Ressalta-se a importancia da adocao de praticas de manejo adequadas nos rebanhos caprinos sergipanos.
