I Method ] Broth microdilution method was used to determine the minimal inhibitory concentration （MIC） of ceftiofur, enrofloxacin and other 11 kinds of antibiotics for antimicrobial agent susceptibility testing of 120 strains of clinical E. coli and the experimental data were processed by WHONET 5.4 software.
