The micro-organism responsible for the majority of infections occurring during the newborn period is the Staphylococcus. While sporadic cases of minor skin infection or the occasional occurrence of septicemia1 due to staphylococci are observed in most newborn nurseries, the more serious clinical forms of staphylococcal disease usually occur during epidemic outbreaks.
