Comparison of the prevalence and molecular characteristics of <i>fosA3</i> and <i>fosA7</i> among <i>Salmonella</i> isolates from food animals in China

Abstract

fosA3 and fosA7 were the primary factors contributing to reduced fosfomycin susceptibility, to different degrees, in these Salmonella isolates. The distinct distributions and molecular characteristics of fosA7 and fosA3 indicated that their origin and evolution in Salmonella were most likely distinct.
