Abstract:

The study was aimed to research the antibiotics resistance of Escherichia coli (E.coli) isolated from different sources of Chifeng and Tongliao areas in Inner Mongolia.Using K-B method, we analysed the resistance situation of 46 strains E.coli isolated from goose, bovine and porcine to thirteen kinds of antibiotic drugs. The resistance rates of E.coli isolated from goose and porcine had the highest resistance to doxycycline hydrochloride drug, which were 95.2% and 93.3%,respectively. The resistant rate of E.coli isolated from bovine had the highest resistance to sarafloxacinhydrochloride,enrofloxacin and hydrochloric acid doxycycline, which was 80.0%. Multi-resistance results showed that the prevalence of E.coli in diseased animals with 6 resistance mainly(23.9%);Bovine source with 7 resistance (40%). The resistance type in general was enrofloxacin/florfenicol/doxycycline/amoxicillin/neomycin sulfate. E.coli from different sources of diseased animals to antibiotics had a serious resistance. So,it is not only necessary for farmers to learn to use antibiotics rationally, but also to develop new drugs that are resistant to drug resistance or new drug allergic to antibiotics.
