It has been reported in all continents except Antarctica and there is evidence for the carriage of Leptospira spp. in almost all mammalian species. The disease is caused by pathogenic serovars of Leptospira spp., which are thin spirochetes characterized by the presence of periplasmic flagella. There are over 250 pathogenic serovars described. Transmission is due to direct or indirect contact with urine of carrier animals and to occupational and recreational activities, which involve infected animals or areas. The “gold standard” test for the diagnosis is MAT (microagglutination), which determines the infecting serovar. The best tool for the control of the disease in animals is the immunization, and there are commercial vaccines available for the most important species. In the case of humans, only populations at risk are vaccinated.esCorporación Universitaria LasallistaFacultad de Ciencias Administrativas y AgropecuariasLeptospirosis caninaLeptospirosisZoonosisEpidemiologíaArticle
