Device-Associated Meningitis by Linezolid-Resistant Staphylococcus haemolyticus in a Vancomycin- Hypersensitive Patient

Postsurgical device-related meningitis caused by multidrug-resistant coagulase-negative staphylococci often complicates the treatment options. We report a rare and, to our knowledge, the first clinical case report of drain-associated meningitis caused by methicillin- and linezolid-resistant Staphylococcus haemolyticus following linezolid therapy in a vancomycin-hypersensitive patient subsequently treated with cotrimoxazole, resulting in clinical improvement. The molecular mechanisms responsible for linezolid resistance were found to be the presence of G2576T mutation in domain V of 23srRNA region, which often arises during linezolid usage and also carriage of cfr gene, which promotes resistance independent of antibiotic pressure. We emphasize on monitoring the rational use of linezolid to avoid the spread of resistance and also comprehensive perioperative care to prevent health care-associated infection.
