Skin scrapings obtained from the lesions of leprosy patients of all types showed 96 % positivity to the serum antibody competition test using monoclonal antibody (ML04)to 35 kDa antigen ofMycobacterium leprae. Further, in vitro culture of full thickness skin biopsies from lepromatous patients were noted to release IgG antibodies toM. leprae with a peak antibody response at 48 h. The significance of this local antibody response toM. leprae in skin has been discussed for its possible use in diagnosing early leprosy.
