Abstract
Strains of staphylococci which have developed resistance to penicillin in the human body yield an inhibitor for penicillin. Penicillin inhibitor was not present in 4 strains which had been made highly resistant by exposure in vitro. Resistance developed in vivo was found, among the strains tested, to be a more permanent characteristic of staphylococci than that acquired in vitro.Keywords
