Abstract: This study was aimed to investigate the resistance of Escherichia coli isolates from cattle farms in Xinjiang to antibiotics. The resistances of Escherichia coli isolates from cattle farms in five regions to commonly used antibiotic were determined using microdilution broth assay. Escherichia coli isolates were highly resistant to ampicillin (up to 39.3%) in all regions, and existed multidrug-resistant, but zero resistance was the dominant. Escherichia coli isolates from E cattle farm in Cherqi town, Baicheng county, exhibited resistant to three kinds of quinolones (6.7%). The results suggested that the resistances of Escherichia coli isolates to commonly used antibiotics were not serious in Xinjiang.

Key words: Escherichia coli; antibiotics; resistance; microdilution broth method
