Adjuvant activity of phenol‐treated cells of Propionibacterium acnes C‐7 in antibody response was investigated in ICR mice. Simultaneous administration (day 0) of P. acnes (i.p.) and sheep red blood cells (SRBC) (i.v.) enhanced the formation of direct plaque‐forming cells (PFC) on day 2, and the formation of indirect PFC response on day 7 and thereafter. Conversely, pretreatment from 11 to 14 days before antigen injection suppressed markedly the antibody response. The potentiation and the suppression of immune response depended on doses of antigen and of P. acnes , the timing of adjuvant injection and the time of assay. The two opposite phenomena caused by P. acnes were also confirmed in antibody response against hamster red blood cells (HRBC). Pretreatment with P. acnes 1 to 14 days before antigen injection suppressed markedly anti‐HRBC antibody response, whereas P. acnes injected simultaneously with HRBC or one day after injection of the antigen induced prolongation of antibody response and the production of 2‐mercaptoethanol‐resistant antibody.
