“…Furthermore, the analysis of 1,693 E. coli isolates from various animal species identified 97 fosA3-positive isolates from beef cattle, pigs, broiler chickens, stray cats, stray dogs, and wild rodents in China (171). Recently, several epidemic fosA3carrying multiresistance plasmids of diverse incompatibility groups have been identified to be disseminated among E. coli from pigs, dairy cattle, and chickens in northeast China (162). Some of these plasmids have been sequenced completely, including the plasmids pECM13 from cattle (113,006 bp, IncI1, and coharboring bla CTX-M-14 , rmtB, aadA2, and bla TEM-1 ), pECB11 from chicken [92,545 bp, F33:A -:B -, and coharboring bla CTX-M-55 , floR, cfr, bla TEM-1 , tet(A), strA, and strB], and pECF12 from chicken [77,822 bp, F33:A -:B -, and coharboring bla CTX-M-3 , rmtB, tet(A), strA, and strB].…”
