Abstract

ABSTRACT SXT/R391 integrative and conjugative elements (ICEs) were detected in 8 out of 125 Proteus mirabilis isolates from food-producing animals in China. Whole-genome sequencing revealed that seven ICEs were identical to ICE Pmi Jpn1, carrying the cephalosporinase gene bla CMY-2 . Another one, designated ICE Pmi Chn1, carried five resistance genes. All eight ICEs could be transferred to Escherichia coli via conjugation. The results highlight the idea that animal farms are important reservoir of the SXT/R391 ICE-containing P. mirabilis .
