Resumo: | The aim of this study was to verify the occurrence of leptospirosis in dogs and the main risk factors related to disease in the city of Uberlandia, Minas Gerais, and analyze the humoral immune response of young dogs with and without defined race against Leptospira interrogans. All samples were subjected to this research Microscopic Agglutination Test (MAT). To determine the prevalence of anti-Leptospira spp. agglutinins were examined 268 samples of blood serum of apparently healthy dogs from different districts in the county. Was detected 28.36% (76/268) of dogs reagents to serovars Autumnalis (34.21%), Tarassovi (23.58%), Canicola (17.11%) and Grippotyphosa (14.47%). Males were more likely to leptospirosis compared to females. The district east had a greater number of dogs reagents. We also evaluated the relationship between the frequency of dogs reactive serum Leptospira spp. with climatic variables in the municipality, for this, 150 samples were examined, 75 were collected during the dry season (June to November) and 75 in the rainy season (December to May). It was determined a frequency of 38%, with the predominance of serovar Autumnalis (15.79%). We noticed a significant difference (p <0.05) in the occurrence of leptospirosis in dogs, more frequently positive from dogs in the rainy season. The humoral immune response against Leptospira interrogans was analyzed in 26 young dogs, and 17 mixed breed (Group A) and nine mixed breed (Group B) after three immunizations with a commercial vaccine against serovars Canicola, Grippotyphosa, Icterohaemorrhagiae and Pomona. There was no statistical difference between the agglutinating titers between Groups A and B (p> 0.05), except the harvest II (p <0.05), in which the group B titers to serovar Autumnalis. To assess the efficiency of vaccine culture anti-Leptospira this research to warn the rich infection that dogs are vaccinated annually submitted. |
