Frequency of and risk factors associated to Leptospira spp. Seropositivity in goats in the state of Sergipe, Northeastern Brazil

2017

ABSTRACT: 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 ≤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.
