Soroprevalência de fatores de risco para leptospirose canina no Médio Sertão Paraibano.

Abstract

The prevalence of leptospirosis was investigated in dogs assisted at the Hospital Veterinary from University Federal de Campina Grande Campus Patos city, State of Paraíba, Brazil, and the risk factors for infection were analyzed. Of the 152 samples, 30 were positive, collected from dogs in the period between July and November of 2008. The diagnostic method run for leptospirosis was the microscopic agglutination test, using a batch of 22 leptospiral serovars. The most prevalent sorovar was found crossing the results of frequency and titer of agglutinins. The prevalence was 19, 73% and most frequent reactant serovars were Autumnalis (13,15%), Grippotyphosa (1,97%), Castellonis (1,32%), e Icterohaemorrhagie (1,32%). The multivariate logistic regression analysis showed that the risk factors for leptospirosis were: mixed breed and animals that had contact with sheeps and goats.
