[Immunoenzyme analysis with corpuscular antigen in the study of zoonotic cutaneous leishmaniasis]

Abstract

Comparative study of sera from patients suffering from zoonotic cutaneous leishmaniasis by indirect immunofluorescence (IIF) and by enzyme immunoassay (ELISA) gave 72.4 and 89.6% positive results, correspondingly, with homologous antigen L. major. Good correlation of these methods was revealed--coincidence in 83% cases. Authors used ELISA with corpuscular Leishmania antigen. The test was superior to IIF in sensitivity and specificity. Creation of type-specific Leishmania test systems for ELISA opens new vistas in studies of the population immune structure in combined zoonotic cutaneous leishmaniasis and visceral leishmaniasis foci.
