NOTE. CRIB-II, Clinical Risk Index for Babies; IQR, interquartile range. aP values from χ2 and analysis of variance. bFor the CRIB-II Score, the number of patients in single-patient configuration was 563 and the number in open-unit configuration was 565.

Staphylococcus species was the most frequent pathogen recov- ered from cultures in both configurations at 43% of all positive cultures. Methicillin-susceptible Staphylococcus aureus and

Streptococcus agalactiae (group B streptococci) were the next most frequent gram-positive pathogens (11% and 8%, respectively) and Escherichia coli was the most frequent
