title: IgG response to some mycobacterial antigens in selected leprosy patients.
abstract: Serum samples from selected leprosy patients with putative tuberculosis were tested by indirect ELISA to determine the level of IgG antibody against six mycobacterial antigen preparations. PCR-positive leprosy patients were confirmed with PGL-I ELISA. A ratio of antibodies to antigens of tuberculosis and leprosy was found to be a valuable serological marker for tuberculosis in long-treated leprosy patients.
