ABSTRACT
The objective of this paper is to study the characteristics of maternal-fetal staphyloccocal infection. A retrospective study among 1,582 infants admitted consecutively to our neonatal intensive care unit was carried out from January 1995 through September 1998. The antenatal history, and the clinical and bacteriological findings and outcome of the infants fulfilling maternal-fetal staphyloccocal infection were analysed. Among 122 (7.7%) maternal-fetal infection, 11 cases (8.9%) of congenital staphyloccal infections were diagnosed in 9 premature and 2 full-term babies. Antenatal invasive procedures were noted in 6 occasions (56%). All the 11 infants developed respiratory and hemodynamic failure. Staphylococcus aureus was the most common organism encountered in maternal bacteriologic data (9/11, 82%) as well as on peripheral sites (9/11, 82%) and in blood cultures (7/11, 64%) performed in the infants. There was one case of methicillin-resistant Staphylococcus aureus. The outcome was favorable for 9 infants. Two very preterm neonates died within the first 72 hours of life. Mother-to-infant transmission of Staphylococcus should be suspected whenever invasive procedures are performed during pregnancy and in the presence of severe neonatal distress associated with an inflammatory response. Prompt and adapted antibiotic therapy allows a favourable outcome.
