Abstract
Pretreatment of mice with Freund's complete adjuvant (FCA) or Corynebacterium parvum depresses the contact sensitivity which otherwise follows immunization with picryl chloride in FCA (PCL/FCA). In contrast, Bordetella pertussis is inactive. The hypothesis that this depression was partly due to the failure of lymph nodes immunized with PCL/FCA to collect lymphoid cells was tested. Mice were pretreated with FCA, C. parvum or B. pertussis, subsequently immunized with PCL/FCA, and injected with 51Cr-labelled normal lymph node cells.
