Methicillin-resistant Staphylococcus lugdunensis in a neonatal intensive care unit: diagnostic challenges and emergence of multidrug-resistance
We report a case of MRSL in an extremely premature neonate, which was the index patient in a neonatal intensive care unit outbreak, and highlight the diagnostic challenges faced in detection, screening and AST. Furthermore, we report the unusual antimicrobial susceptibility profile of this MRSL strain, caused by a multidrug-resistance plasmid with potential for transmission among staphylococci.
