IgG response to purified 65- and 70-kDa mycobacterial heat shock proteins and to antigen 85 in leprosy.

IgG antibody response to mycobacterial heat-shock proteins (hsp) (the 70-kDa antigen from Mycobacterium tuberculosis and M. bovis BCG; the 65-kDa antigen from M. leprae and M. bovis BCG) and to the fibronectin-binding antigen 85 from M. bovis BCG was analyzed in a dot-blot assay in plasma from leprosy patients and their contacts. Most plasma--whatever the… CONTINUE READING
