A rapid (<3h) and reliable multiplex PCR was developed for detecting simultaneously known plasmid-mediated fos genes conferring acquired resistance to fosfomycin. Our technique was tested on a collection of Escherichia coli isolates previously identified as bearing the fosA-, fosC- and fosL-like genes, showing a sensitivity and a specificity of 100%.
