Abstract
ABSTRACT
Two antigens from
Mycobacterium tuberculosis
, ESAT-6 and MPT64, elicited delayed-type hypersensitivity (DTH) skin responses in outbred guinea pigs infected with
M. tuberculosis
by the aerosol and intravenous routes but not those sensitized with
M. bovis
BCG or
M. avium
. The DTH epitope of ESAT-6 was mapped to the C terminus. Nonresponders to the individual antigens were found, but all animals responded to a combination of ESAT-6 and MPT64 or their respective minimal target peptides. Correspondingly, these molecules could form the basis of a new skin test for tuberculosis.
