T cells from Mycobacterium avium-infected C57BL/6 mice reacted to culture f
iltrate, envelope, and cytosol proteins and to fractions obtained from thes
e proteins. Multiple targets were recognized, such as 29- to 45-kDa and <21
-kDa antigens of the culture Filtrate, antigens of around 30 kDa in the env
elope and cytosol, and 45-to 116-kDa proteins in the envelope.
