Carriage of Corynebacterium acnes in school children in relation to age and race

SUMMARY The prevalence of Corynebacterium acnes on the foreheads of male and female children of caucasoid and negroid origin has been investigated using a semi-quantitative technique. Few organisms were recovered from children of less than 12 years of age. The increase in count occurred earliest in Negroid girls and latest in caucasoid boys. This may be related to the age of puberty.
