using a contact hypersensitivity model in balb/c mice we have previously been able to show that corynebacterium parvum or c. parvum serum ( c.p.s . ) of mice treated 24 hr before with c. parvum inhibited the suppressor t-lymphocyte ( ts-cell ) response induced by epicutaneous antigen overload with 2,4-dinitrofluorobenzene ( dnfb ) or by i.v . injection of 2,4-dinitrobenzene sulfonic acid ( dnbso3 ) without inhibition of the t effector cell response ( tdh-cell ) .
