Multi-resistant Staphylococcus haemolyticus in a neonatal unit in New Delhi.

Abstract

We describe a cluster of infections in a neonatal nursery due to an infrequently reported staphylococcal species, Staphylococcus haemolyticus. S. haemolyticus resistant to penicillin, methicillin, gentamicin, erythromycin, chloramphenicol and tetracycline (PMGECT) was isolated from a series of infections in neonates (conjunctivitis 6, blood 2, pustules 2) over a period of 3 weeks in a neonatal nursery. Surveillance cultures from 22 neonates, their mothers in an adjacent maternity ward and staff revealed that S. haemolyticus with three resistance patterns (PMGECT, PMG and PME) was circulating in the unit. It was isolated from two caesarian wounds, the nose/ear/umbilicus of six asymptomatic infants and from the noses of three mothers and one nurse. S. haemolyticus showed a higher frequency of resistance to antibiotics than Staphylococcus aureus and Staphylococcus epidermidis isolated from the unit at the same time. Local and asymptomatic infections were treated with local neosporin application whereas netilmicin was used to treat systemic infection. Infections were controlled by emphasising the importance of handwashing, asepsis and eye care.
