title: Cellular immunity to penicillin in newborns.
abstract: A leukocyte migration micromethod has been used to study the cellular immunity to penicillin (CIP) in newborns. No detectable CIP has been found in newborns who had not been treated with penicillin. Fifteen per cent of the newborns treated with pencillin were found to have a CIP as early as the 12th day of life.
