      A low molecular weight antigenic fraction has been isolated from saline-soluble extracts of cattle filarial parasiteSetaria digitata. This glycoprotein fraction (Fr III) which appears to have low phosphorylcholine content cross-reacted with infective larval (L3) antigens ofWuchereria bancrofti. Binding of human chronic filarial serum with L3 antigens could be inhibited partially by Fr III. The fraction elicited immediate cutaneous hypersensitivity reaction in people living inWuchereria bancrofti endemic regions. The proportion of skin test positive cases was found to be highest in endemic normals in contrast to infected cases. IgE levels were however not different in chronic filariasis and in endemic normals (or in asymptomatic microfilaraemic carriers). On the other hand, specific IgG level was considerably enhanced only in chronic filariasis

      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.
