To assess the utility of umbilical surveillance cultures for methicillin-resistant Staphylococcus aureus colonization in neonates, we performed a retrospective cohort study in patients in a neonatal intensive care unit (NICU). Over 6 years, 6/1,908 (0.32%) umbilical cultures were positive, all from patients with a concomitant positive culture from either the nares or rectum. The cost of umbilical cultures was $184,535. The value of neonatal umbilical methicillin-resistant S. aureus screening appears limited.

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
