Parasitological diagnosis, using staned smears, culture and pathological examination of biopsy, was studied in 146 patients infected with mucocutaneous leishmaniasis, in Bolivia and Peru. The most efficient parasite detecting technique appeared to be the smear examination in cutaneous lesions (33 % positive) and the pathology in case of mucous lesions (28 % positive). In both, cutaneous and mucous lesions, the parasites were found most frequently in old lesions.
