| Summary: | Leishmaniasis is a widespread disease caused by species of the genus Leishmania. In Colombia, this zoonosis is endemic in rural areas with a high prevalence in the departments of Antioquia, Santander, Meta, Tolima and Nariño. Dogs are the most important domestic reservoirs of the pathogen, given the epidemiological importance of dogs in the control of leishmaniasis is needed to determine the prevalence of Leishmania spp. in canine population of the rural area of Ibagué and to identify potential risk factors related to the presence of this parasite. A cross-sectional study was carried out in 173 dogs from the rural area of Ibagué. Leishmania spp. was detected by amplifying the Internal Transcribed Spacer (ITS-1) and two regions of the hsp70 gene through PCR. Factor associations were calculated through the Chisquare and odds ratio. Prevalence of Leishmania spp. infection in dogs was of 91.33% (158/173), where 36.71% (58/158) of the Leishmania spp. positive dogs showed one or more clinical signs of canine leishmaniasis and 63.29% (100/158) of the dogs were asymptomatic. Factors associated with the presence of the parasite did not show significance. In addition, hsp70D-PCR was proved to be highly efficient for the detection of Leishmania spp.
