Abstract
Leishmaniases are zoonotic diseases caused by protozoa of the genus Leishmania. The disease has two clinical manifestations described in humans: visceral (VL) and cutaneous (CL) leishmaniasis. In Brazil, there has been an expansion of human VL. The participation of the dog as a reservoir of Leishmania infantum, the agent of VL, is important for the epidemiology of the disease since canine cases generally precede human cases. The present study aimed to evaluate the occurrence of Leishmania spp. infection in dogs in the municipality of Ji-Paraná by PCR assays using blood samples. Leishmania DNA was detected in two of the 105 studied dogs. The PCR products were sequenced and confirmed that the two samples (1.90%) correspond to L. infantum. The dogs had allochthonous history. Therefore, the positive results found here should serve as a warning to public health agencies. This is because Ji-Paraná is the third municipality to register cases of canine leishmaniasis (CanL) in Rondônia state. Thus, reinforcing the importance of expanding studies on the epidemiology and surveillance of VL in the region.
