Abstract Leishmania species of the subgenus Viannia account for 88\% of all cases of leishmaniasis recorded in Colombia. Correct diagnosis is essential as infection with members of this subgenus can produce disfiguring destruction of the mucosa. Several methods are available to diagnose leishmaniasis in clinical samples. More recently, the polymerase chain reaction (PCR) has been used, with varying sensitivities and specificities depending on the primers used. In this paper we report on the sensitivity and specificity of PCR primers B1/B2 used on clinical samples and compare their use to the conventional parasitological methods. PCR alone is more sensitive than any single conventional method used, but a combination of conventional methods produced comparable sensitivity. PCR is well suited for use in selected cases and as a test for mucosal leishmaniasis.
