Persistent Staphylococcus capitis septicemia in a preterm infant.

Abstract

A preterm infant had persistent Staphylococcus capitis septicemia with 11 consecutive positive blood cultures over a period of 33 days. The clinical evidence suggested that the source of infection probably originated from the gastrointestinal tract. The combination of rifampin and linezolid treatment, together with prolonged stoppage of enteral feeding, successfully terminated the infection. Rifampin and linezolid should be considered as alternative antimicrobial agents when glycopeptides fail to eradicate Gram-positive pathogens from the host.
