Leptospira interrogans in a canine population of Greater Buenos Aires: Variables associated with seropositivity
We determined the seroprevalence of leptospirosis in a suburban canine population for the purpose of analyzing the association between different individual and environmental variables and seropositivity for leptospirosis. The study, which was cross-sectional, was performed in July 1992 in a neighbor...

Serologic measurements were performed by the microagglutination technique with the use of 10 different serotypes of Leptospira interrogans.

Seroprevalence in females was less common than in males (P < 0,05) and in puppies less than 1 year old it was less common than in older animals (P < 0,01). Street behavior in the dog and the presence of stagnant water in front of the owner's dwelling were the most important of the risk factors examined. The associations between seropositivity on the one hand and contact with trash deposits, hunting behavior and the presence of rodents inside the dwelling on the other were not statistically significant.
