BERMUDEZ C, Soledad; PULIDO M, Martín  and  ANDRADE B, Roy. Seroprevalence of in canines and humans Leptospira spp in three neighborhoods of Tunja, Colombia. Rev.MVZ Cordoba [online]. 2010, vol.15, n.3, pp.2185-2193. ISSN 0122-0268.

Objective. To establish the seroprevalence of Leptospira spp in the canine and human populations of slum neighborhoods in the city of Tunja. Materials and methods. Sixty-one canine serums were obtsined in slum neighborhoods of the city, sera of 46 human pet owners were also obtained, an interview was done as well. The microagglutination-lysis (MAT) technique was used to process the samples for six serotypes of Leptospira spp. Results. 67.2% of the canine population tested was found to be seropositive, the seroprevalence by serovars resulted in 14.8% for L. icterohemorragica; 8.2% for L. pomona; 9.85% for L. hardjo; 18% for L. canicola, 6.6% for L. automnalis and 9.8% for L. sejroë. Humans showed a prevalence of 21.7%, the distribution was as follow: L. automnalis (4.35%); L. hardjo (2.17%), L. sejroë (6.52%), L. icterohaemorragiae (6.52%) and L. canicola (2.17%). Conclusions. These results showed a great problem with high impact, in contrast with prevalence rates in other municipalities in Colombia, revealed a high positivity rate in this area and produces big concern because of its rapid dissemination, which may be caused by the close contact between vectors, such as rodents and canines.
