Abstract

Three patients with furunculosis due to a pathogenic strain of Staphylococcus aureus became free of furuncles after S aureus strain 502A was purposely substituted. Relapse of furunculosis occurred when 502A was lost and the original strain reacquired. Nine other patients lost their furuncles after replacement of a pathogenic strain by 502A. Abscess formation is a strain-related phenomenon in these patients, and disappearance of furuncles was not a chance event but was related to the implantation of strain 502A.
