Isolation and Identification of a Pathogenic E. coli Strain Causing Diarrhea in Foxes

摘要

cqvip:[Objectives]The study aimed to identify the pathogenic E. coli strain that caused diarrhea in foxes and to analyze its drug sensitivity. [Methods]A pathogenic E. coli strain was isolated from dead foxes with diarrhea. By conventional bacterial isolation and culture,morphological observation,pathogenicity test and K-B disc method,the isolated strain was identified as pathogenic E. coli. [Results]The isolated pathogen was highly sensitive to ceftriaxone,cefotaxime,ciprofloxacin and lincomycin,moderately sensitive to enrofloxacin,neomycin,gentamycin,spectinomycin,florfenicol,amikacin and polymyxin,and resistant to ampicillin,amoxicillin and doxycycline. [Conclusions]This study provided reference for the prevention and control of diarrheal diseases in foxes in Qinhuangdao region.
