title: Staphylococcus epidermidis-associated enterocolitis.
abstract: Nineteen infants (mean +/- SD gestational age 30 +/- 2 weeks, birth weight 1.28 +/- 0.53 kg) with Staphylococcus epidermidis bacteremia were found on retrospective chart review to have had signs and symptoms of acute enterocolitis. This S. epidermidis-associated enterocolitis constituted 37% of the 51 cases of enterocolitis and 23% of the 81 cases of S. epidermidis sepsis during the study period. S. epidermidis-associated enterocolitis was relatively mild compared with other forms of enterocolitis. Although abdominal radiographs showed markedly abnormal bowel gas patterns with distended bowel loops and bowel wall edema, only one infant had pneumatosis intestinalis and none had portal venous or free intraperitoneal gas. Only three infants had neutropenia, and five had thrombocytopenia. None of these infants required surgical intervention. Although bloody stools often persisted for weeks, none of the neonates had prolonged feeding intolerance or development of a stricture. We conclude that S. epidermidis infection is commonly associated with a mild form of enterocolitis in the neonate and that this association should be considered when selecting antibiotics for therapy.
