摘　　要：对4株鸡致腹泻大肠杆菌分离株分别进行了培养、生化鉴定和抗药性测试.结果表明:4株鸡大肠杆菌对青霉素类等14种药物都产生广泛的抗药性,但对喹诺酮类药物、氨基糖甙类药物、菌必治及一些价格低廉的药物(如新霉素、复方新诺明和痢特灵等药物)较为敏感.Each of the 4 strains of EVEC was incubated, tested for the biochemical properties and identified. A drug-sensitivity test to 30 drugs was performed with 4 chicken pathogenic E. coli strains. The result demonstrated that each E. coli strain had universal resistance to the drugs such as penicillium. But the 4 E. coll strains had the high bacteriostasis and widest ranges for the quinolone, aminoglicoside, rocephin and some cheap ones like necomycin, SMZ, furazolidone. The sensitivity of each kind of medicine was slightly different.
