[Allochthonous cases of canine visceral leishmaniasis in Paraná, Brazil: epidemiological implications].

The south region is the only area in Brazil that does not present autochthonous cases of visceral leishmaniasis (VL), however, in the state of Paraná, dogs and humans have been found showing a VL compatible clinical profile. In view of this problem, the present work aimed at isolating and identifying the parasite and determining the cases autochthony. All animals clinically suspect of VL were clinically evaluated, and had samples of their blood collected for hemoculture (NNN culture medium), serology, PCR and RAPD-PCR, hemogram, and biochemical assays.
