| Abstract | Tissue imprints on Giemsa stained slides from dogs were used to investigate the presence of Leishmania amastigotes by either optical microscopy (OM) or Polymerase chain reaction (PCR) detection of DNA. Samples from skin, spleen, lymph node, liver and bone marrow from a Leishmaniasis endemic area dogs where Leishmania (Leishmania) chagasi and Leishmania (Viannia) braziliensis are sympatric were studied. Dogs were initially diagnosed by Indirect Immunofluorescence (IIF), as which 39 were IIF positive (> or = 1:40) and 16 negative. The IIF positive dogs were clinically grouped as symptomatic (n = 15), oligosymptomatic (n = 12) and asymptomatic (n = 12). Although PCR positivity was higher in symptomatic dogs, specially their skin samples, there was no significant difference among clinical groups or organs examined. Ten (62.5%) out of 16 IIF and OM negative animals were positive for PCR in at least one organ. Forty-eight positive PCR amplicons were further submitted to RFLP for Leishmania identification. All dogs were infected with L. (L.) chagasi except one, infected with L. (V.) braziliensis. PCR was more efficient than IIF and OM to diagnose canine visceral Leishmaniasis (CVL), regardless of the organ examined and the clinical form present. The use of PCR together with serology helps determining the extension of sub clinical infection in CVL endemic areas and provides a better estimate of the number of dogs to be targeted for control measures. In conclusion, our data reinforce the need for a specific diagnosis of canine infection in areas where diverse Leishmania species are sympatric and demonstrate that PCR-RFLP can be used to identify Leishmania species in dog tissue imprint stained slides | pt_BR |
