Host defense mechanisms against Herpes simplex virus. I. Control of infection in vitro by senstized spleen cells and antibody.

abstract：:The outcome of coccidioidomycosis depends to a large extent on the effectiveness of the T-cell-mediated immune (CMI) response to the fungal pathogen. For this reason, identification of Coccidioides immitis antigens which stimulate T cells is important for understanding the nature of host defense against the organism a...
