Cell-mediated immunity (CMI) plays an important role in resistance against
leishmaniasis. Delayed-type hypersensitivity (DTH) reaction measured by skin
testing is a practical method of evaluation of CMI and is used as an aid to diagnosis
and for epidemiological assessment of exposure to leishmanial infection. Skin
testing in leishmaniasis, generally known as Montenegro or leishmanin test, requires
a standard antigen. At present no uniform and standard leishmanin is available for
skin testing in leishmaniasis. The present work describes the preparation and testing
of an antigen from Leishmania major using standard conditions. Three dilutions of
this antigen were tested in recovered individuals in an endemic area in Iran. The
results obtained showed that leishmanin preparation exhibited high specificity and
sensitivity, and strong potency.
