Abstract
To determine the prevalence of Leptospiraspp. in humans and cattle in the municipality of Toca (Boyaca) using the microagglutinationlysis technique (MAT) and to identify the Leptospira serovars present in dairy herds. Materials and Methods: A cross-sectional study was made to determine antibodies against several Leptospira spp. serovars. Blood samples from 37 workers and 133 female bovines from the municipality of Toca (Boyaca) were taken in tubes without anticoagulant. The laboratory analysis was done through the MAT technique. The serovars investigated were icterohaemorrhagiae, pomona, hardjo,canicola, sejroe and autumnalis. Results: A prevalence of 54.2% (64/133) was found in cattle, as well as positivity to L. icterohaemorrhagiae 11.3%, L. pomona 13.5%,L. hardjo 6.0%, L. canicola 8.3%, L. sejroe 6.8%, and L. autumnalis 8.3%. For humans, the prevalence found was 29.7% (11/37) with positivity for the serovars L. icterohaemorrhagiae 5.4%, L. pomona 5.4%, L. hardjo 2.7%, L. autumnalis5.4%, L. canicola 10,8%. The sejroe serovar was negative in humans. Conclusions: The presence of leptospirosis in dairy cattle can mean a threat to livestock production. In addition, finding positive individuals to Leptospira shows a public health implication in the analyzed area due to the zoonotic nature of the pathogen.
