Induction of delayed-type sensitivity to Leishmania parasite in a case of leishmaniasis cutanea diffusa with BCG and cord-factor (Trehalose-6-6' dimycolate).

The delayed hypersensitivity against the leishmania parasite was restored to a patient who had suffered from diffuse cutaneous leishmaniasis (DCL) for 26 years, by the application of an ointment containing heat-killed and lyophilized BCG and cord-factor (trehalose-6-6'-dimycolate) after stripping the affected and adjacent areas with scotch-tape.
