Identification of the Multiresistance Gene poxtA in Oxazolidinone-Susceptible Staphylococcus haemolyticus and Staphylococcus saprophyticus of Pig and Feed Origins.

ABSTRACT: Previous studies on the prevalence and transmission mechanism of oxazolidinone resistance gene poxtA in CoNS are lacking, which this study addresses. By screening 763 CoNS isolates from different sources of several livestock farms in Guangdong, China, 2018-2020, we identified that the poxtA was present in seven CoNS isolates of pig and feed origins. Species identification and multilocus sequence typing (MLST) confirmed that seven poxtA-positive CoNS isolates were composed of five ST64-Staphylococcus haemolyticus and two Staphylococcus saprophyticus isolates. All poxtA-positive Staphylococcus haemolyticus isolates shared similar pulsed-field gel electrophoresis (PFGE) patterns. Transformation assays demonstrated all poxtA-positive isol
