Recombination-free phylogenetic tree including MLST, country, source, resistance, resistance gene and mutation data. Linezolid resistance in US isolates was attributed solely to the G2576T mutation of the 23S rRNA gene sequence. In contrast, linezolid resistance in Pakistan isolates resulted from different combinations of the acquired resistance genes optrA, poxtA and a cfr-like gene. Vancomycin resistance was observed in 90.6% (87/96) of the isolates and dalbavancin resistance was observed in 88.5% (85/96). Daptomycin resistance was observed in 3.13% (3/96) of the isolates with an additional 68.8% (66/96) classified as susceptible dose-dependent.
