Spread and Molecular Characteristics of Enterobacteriaceae Carrying fosA-Like Genes from Farms in China.

ABSTRACT: In this study, we aimed to investigate the occurrence and molecular characteristics of fosfomycin-resistant Enterobacteriaceae isolates from pig, chicken and pigeon farms in Guangxi Province of China. A total of 200 fosfomycin-resistant strains were obtained from food animals and their surrounding environments, with the fosA, fosA3, and fosA7.5 genes being detected in 26% (52/200), 10% (20/200), and 5% (10/200), respectively. Surprisingly, three fosA7.5-producing E. coli isolates were found to be concomitant with fosA3. Most of the fosA-like-gene-positive isolates were multidrug-resistant strains and consistently possessed bla_{CTX-M-1/CTX-M-9}, floR, and bla_TEM genes. Only fosA3 was successfull
