Methicillin-resistant Staphylococcus aureus in Neonatal Intensive Care Unit
Figure 2. . A) Nosocomial transmission of non–multidrug-resistant (MDR) methicillin-resistant Staphylococcus aureus (MRSA) in the premature neonatal ward. Dotted lines represent hospitalization until first non-MDR MRSA isolation. Solid lines represent hospitalization after first non-MDR MRSA isolation until discharge. B) pulsed-field gel electrophoresis of MRSA outbreak isolates; lanes 1–10: ST45-MRSA-IV outbreak strains isolated from neonates; lanes 11–12: ST45-MRSA-IV outbreak strains isolated from nurses; lane 13: ST45 methicillin-susceptible S. aureus strain from a community survey; lane 14: common nosocomial MRSA strain ST5-MRSA-II.
