Linezolid-resistant and vancomycin-resistant <i>Enterococcus faecium</i> urinary isolate in a pediatric B-ALL patient

This case underscores the diagnostic challenges in detecting emerging linezolid resistance in <i>E. faecium</i>, particularly in immunocompromised patients. Accurate, timely susceptibility testing and improved access to confirmatory or molecular diagnostics are essential to guide therapy for VRE where linezolid remains one of the few viable therapeutic options.
