ANTILEPTOSPIROSIS SEROLOGICAL FREQUENCY IN DOGS: ITS CORRELATION WITH RODENTS AND ENVIRONMENTAL FACTORS, IN AN URBAN AREA

ABSTRACT

The aim of this study was to ascertain the antileptospirosis serological frequency in dogs and its correlation with rodents and environmental factors in a 32 km2 urban area of Botucatu, SP, Brazil. One thousand blood samples were collected from dogs at 20 homogenously distributed stations. The microscopic serum agglutination diagnostic test (SAM) was used with 24 Leptospira spp. serovars. From the 1,000 samples tested, 17.9% were reactive. Reactive dogs who had contact with rodents (23.68%) were significant (p < 0.05) in relation to those without contact (15.37%). There was no statistical significance (p > 0.05) between seropositive animals from homes connected (18.10%) and not connected (13.63%) to the public sewage system. There were reactions to 20 serovars, the most important were: castellonis (28.68%), autumnalis (19.12%), pyrogenes (17.65%), icterohaemorrhagiae (11.03%), and canicola (9.56%).
