Abstract:
The pathogens were isolated and purified from the stomach,jejunum and rectum tissues of a Yunnan snub-nosed monkey who died of vomiting,oral and nasal chyme,and abdominal dis-tension,and the species and biological characteristics of the pathogens were studied by biochemical identification,PCR identification,drug susceptibility test,pathogenicity test,serotype identifica-tion,and drug resistance gene and virulence gene analysis.The results showed that the pathogens i-solated from stomach,jejunum and rectum were Escherichia coli(E.coli)serotype O127,belong-ing to enteropathogenic E.coli.They were resistant to cefoxitin and sensitive to gentamicin,gati-floxacin and ciprofloxacin.All the three strains carried drug resistance genes blaTEM and blaCTX-M and virulence genes opmA and opmC.This study provides reference and data support for the prevention and control of enteritis caused by E.coli in Yunnan snub-nosed monkey.
