Isolation, identification and antibiotic resistance of pathogenic E.coli
Abstract：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.
