摘要

SUMMARYThis study nvestigates the dicordance between the restriction criteria required for the transfer of cellular resistance toListeria monocytogenes(LM) and those for the transfer of delayed type hypersensitivity toListeriaantigens. Infective bacteria elicity bothRTl.A‐restricted T cells andRT1.B.‐restricted T cells. Both populations of t cells mediate lymphoblast localization and macrophage accumulation, which are reactions characteristic of delayed type hypersensitivity (DTH), and cause macrophage activation with rapid and efficient bacterial elimination, which is an expression of cellular resistance. If alcohol‐killedListeriaorganisms (pLMA) are injected, only theRTl.B‐restricted T cell subset is triggered. Direct comparison of lymphoblast localization in LM infection sites and the expression of resistance of resistance revealed that efficient resistance may be mediated by small numbers of lymphoblasts and that below a certain threshold there is no correlation between lymphoblast localization and the level of res
