Isolation and identification of Proteus mirabilis from chicken and study of its drug resistance

To investigate the drug resistance of Proteus mirabilis,1 829 cotton swabs of cloacal samples were collected from the broilers in the appointed poultry farms.67 strains of Proteus mirabilis were obtained through isolation,purification,and identification,and the isolation rate was 3.66%.The 67 strains of Proteus mirabilis were tested for drug resistance using eleven kinds of antibiotics.The results showed that the Proteus mirabilis from the region generally possessed higher levels of drug resistance against the eleven kinds of antibiotics.The average resistance rates reached more than 80.00% in the nine kinds of drugs including colistin E,florfenicol,bacteresulf,enrofloxacin,cotrimoxazole,ampicillin,doxycycline,spectinomycin and tetracycline.The drug resistance against gentamicin was 62.69% and the drug resistance against ceftiofur was zero.The results indicate that Proteus mirabilis has a higher isolation rate in the broiler farms,and is one of the pathogens that need to be focused on monitoring in the clinic by veterinarian.
