    Abstract:

    Objective To investigate the contamination of Arcobacter in retail chicken meat in Shijiazhuang City,and provide basic data support for the distribution characteristics and prevention and control of Arcobacter in Shijiazhuang. Methods A total of 90 chicken meat samples were randomly collected from wholesale markets, supermarkets and butchers in Shijiazhuang. Enhanced membrane filter technique was used to isolate Arcobacter from the chicken meat samples, multiplex polymerase chain reaction(PCR)detection was used to identify Arcobacter and 16S rRNA and rpoB genes of the Arcobacter isolates were sequenced and analyzed to confirm the detection result. Results Among the 90 samples, 60 samples were Arcobacrer positive(66.67%),and 86 Arcobacter strains were isolated. Forty-nine of the eighty-six isolates were A.cryaerophilus and the rests were A.butzleri. Among the 60 Arcobacter positive samples, 45 samples (75.00%) were A.cryaerophilus positive and 35 samples (58.33%) were A.butzleri positive. About 22.22%(20/90) samples were cocontaminated with A.cryaerophilus and A.butzleri. There were significant differences in the contamination rate of Arcobacter in different markets. Conclusion In Shijiazhuang City, the contamination of Arcobacter in retail chicken meat was serious, and the contamination rate of A.cryaerophilus was higher than A. butzleri in chicken meat samples. The contamination rate of A.cryaerophilus and A.butzleri were high.
