Previous studies of the Syrian hamster have demonstrated a lack of cytotoxic T lymphocyte (CTL) activity in vaccinia virus-infected animals. Our laboratory has reexamined CTL activity in both the classical inbred strains, MHA, CB, and LSH, as well as the recently inbred strain MIT. Primary and secondary CTL specific for the immunizing antigen have been detected after in vitro culture in MIT but were not demonstrable in the classical strains. Only lymph node cells of the responding animal demonstrated this activity, spleen cells being phenotypically devoid of such a response. Identification of the cell responsible for cytolysis as a T cell was demonstrated by nylon wool nonadherence, specificity on Con A blasts, and the lack of surface immunoglobulin, as demonstrated by cell-sorter analysis.
