(A) Genotypic identification of blaCTX-M gene via PCR in E. coli strains isolated from beef cattle in china's Sichuan-Chongqing Circle; where, M: 2000 bp DNA Marker, 1: positive controls, 7 and 11: CTX-M negative isolates while others are positive, and 14: negative controls. Original Images of full-length gels are presented in Supplementary Fig. 4. (B) Genotypic identification of blaSHV gene via PCR in E. coli strains isolated from beef cattle in china's Sichuan-Chongqing Circle; where, M: 2000 bp DNA Marker, 1: positive controls, 5, 8, 10, and 12: SHV negative isolates while others are positive, and 14: negative controls. Original Images of full-length gels are presented in Supplementary Fig. 5. (C) Genotypic identification of blaTEM gene via PCR in E. coli strains isolated from beef cattle in china's Sichuan-Chongqing Circle; where, M: 2000 bp DNA Marker, 1: positive controls, 4, 5, 7, 10 and 12: TEM negative isolates while others are positive, and 14: negative controls. Original Images of full-length gels are presented in Supplementary Fig. 6.
