由湛江市3个养猪场采集到40份仔猪黄痢、白痢腹泻粪便样品，共分离到40株大肠杆菌，其中7株是致病性大肠杆菌，三个猪场致病性大肠杆菌的分离率分别为15．4％、10％和43％。对7株致病l挂大肠杆菌进行药物敏感性试验，结果表明：它们均对恩诺沙星、菌必治和丁胺卡那霉素敏感，而对复方新诺明、阿莫西林、氨苄青霉素、四环素和庆大霉素的耐药率为100％，对氯霉素、头孢氨苄和痢特灵的耐药率为85．7％，对卡那霉素和链霉素的耐药率为57．1％，对氟哌酸和环丙沙星的耐药率为14．3％。猪场选用较敏感药物来防治仔猪大肠杆菌病，使疫病得到了有效控制。

Forty Escherichia coli strains were isolated from 40 fecal samples of white scour and yellow scour of piglets from 3 pig farms of Zhanjiang city. Seven strains of them were pathogenic. The isolation rate of the pathogenic E. coli in 3 pig farms were 15.4%, 10% and 43% respectively. The antibiotic resistance of these seven strains showed that they were all sensitive to enrofloxacin, ceftriaxone and amikacin and resistant to cotrimoxazole, amoxicillin, ampicillin, tetracycline and gentamicin. 85.7% strains were resistant to chloramphenicol, cephalexin, furazolidone and 14.3% strains were resistant to norfloxacin and ciprofloxacin. So the sensitive drugs to pathogens should be selected and applied to prevention and control of the disease.
