title: A long-lasting enhancing effect of anti-tuberculin antiserum on delayed-type hypersensitivity reaction in BCG-infected guinea pigs.
abstract: Anti-tuberculin serum and anti-BCG immunoglobulins from immunized guinea pigs were transferred into recipient guinea pigs which had been infected with BCG. An enhancement of tuberculin skin reactivity was observed 7 and 35 days after transfer of homologous antiserum in comparison to a control group. This indicates a modulating effect of humoral factors, presumably specific antibodies on the expression of delayed-type hypersensitivity reaction after immunostimulation with BCG.
