Description
Summary:To the Editor–Methicillin-resistant Staphylococcus aureus (MRSA) occasionally causes outbreaks in hospitals, often in departments where newborns receive treatment.1,2 Hospital-acquired infections by MRSA may have a lethal outcome3 and expenses for infection control measures for containing hospital outbreaks may become very high.4 Surveillance of MRSA is essential for early detection and interruption of transmission. For S. aureus, results include individual MLST ST, antibiotic resistance mechanisms (resistance genes and mutations associated with resistance), and virulence gene profiles. [...]all isolates from hospital B in the outbreak cluster were cultured later than the isolate from the index patient. [...]the higher resolution obtained from cgMLST did support suspicion of transmission of the outbreak strain between the hospitals but did not confirm this taking place via transfer of the index patient from hospital B. Another 2 clusters were detected among isolates from hospital B (Fig. 1).
