Leptospirose e brucelose em catetos (Pecari tajacu Linnaeus, 1758) no Nordeste do Brasil.

Abstract

The collared peccary (Pecari tajacu) is a species with zootechnical potential for the production of meat and leather, considered one of the wild species most consumed in Brazil. Thus, more research is needed on the diseases that affect the Pecari, and the diseases that are transmitted from animals to man, such as zoonoses, are of great importance in public health. Therefore, the objective of this project was to study the epidemiological aspects of leptospirosis and brucellosis in breeding hounds legalized in Brazil. Collared peccary of legalized breeders were used in the Northeast, in which collection of blood and vaginal and preputial swabs were performed for anti-Leptospira sp. and anti-Brucella abortus. These were submitted to Microscopic Soroagglutination (MAT) analysis with subsequent titration of antibodies and the PCR technique was performed for leptospirosis. For brucellosis, the Acidified Buffered Antigen (AAT) test was used. All animals were negative for Brucella spp. Among the animals tested, four (8.3%) were seropositive for Leptospira sp. and reacted to serogroup Iterophaemorraghiae, which is the main agent of human leptospirosis in Brazil and has adaptation to rodents. The low prevalence in the study of animals positive for leptospirosis and brucellosis may be related to the breeding system and the management that are submitted, however it can not be disregarded the participation of the same as reservoirs in the infections.
