Abstract
Abstract Background Despite the advances in current healthcare, bone and joint infections (BJIs) are a major clinical challenge that frequently involve prolonged systemic antibiotic use. Healthcare providers consider tedizolid an attractive candidate for therapy in adults and children with BJI. Objectives We tested tedizolid against a US and European collection of Gram-positive BJI isolates (n = 797) consecutively collected from 2014 to 2017. Methods Organisms were tested by broth microdilution susceptibility methods following current CLSI guidelines and interpreted by both CLSI and EUCAST breakpoint criteria. Results Staphylococcus aureus (59.3%; 58.6% in the USA and 60.4% in Europe) was the most common pathogen with a 29.6% MRSA rate and tedizolid MIC50/90 of 0.12/0.25 mg/L (100% susceptible). CoNS (15.0% of BJI in adults and <5% in children) had tedizolid MIC50/90 values of 0.12/0.12 mg/L (99.1% susceptible). Tedizolid exhibited MIC50/90 values of 0.12/0.25 mg/L for all streptococci and enterococci. Overall, high susceptibility rates (>95%) for vancomycin, daptomycin and linezolid were observed and, based on MIC90 values, tedizolid (MIC90 0.12–0.25 mg/L) was 4- to 8-fold more potent than linezolid (MIC90 0.5–2 mg/L) against this collection of Gram-positive pathogens causing BJI. Conclusions This study showed that tedizolid had potent in vitro activity against contemporary Gram-positive cocci causing BJI in adults and children in US and European hospitals.
