Staphylococcus pettenkoferi: an underrecognized species with clinically relevant antimicrobial resistance. A comprehensive genomic European study. (PubMed, Emerg Microbes Infect) - Sep 17, 2026 - "Susceptibility rates were below 70% for cefoxitin, erythromycin, and levofloxacin, whereas high susceptibility (>90%) was observed for vancomycin, teicoplanin, dalbavancin, aminoglycosides, oxazolidinones, trimethoprim-sulfamethoxazole, fusidic acid, and tetracycline. Nearly all isolates (92.1%) were fosfomycin-resistant...This study provides a comprehensive genomic and phenotypic assessment of antimicrobial resistance in S. pettenkoferi, revealing widespread multidrug-resistant lineages, including ceftobiprole- and daptomycin-resistant isolates across distinct clades. These findings underscore the need for continued surveillance and improved diagnostics for this increasingly encountered CoNS species."
