摘要(Abstract):

[Objective] The paper was to determine the pathogen causing fox pneumonia in a breeding factory in Changli County. [Method]Through autopsy, a dominant strain was isolated from the lung of dead foxes, which was then performed Gram staining, 16 S rRNA sequence analysis and biochemical identification. [Result] The strain was negative in Gram staining, and was identified as E. coli through 16 S rRNA sequence analysis and biochemical identification. Drug susceptibility test was conducted using 15 kinds of drug susceptibility papers. The E. coli was sensitive to florfenicol, enrofloxacin, ceftriaxone, norfloxacin; intermediately sensitive to amikacin, gentamicin; and strongly resistant to penicillin, ampicillin,cefradine, sulfamethoxazole, lincomycin, streptomycin and amoxicillin. [Conclusion] It is difficult to treat E. coli causing fox pneumonia with traditional antibiotics clinically.
