Compylobacter fetus subsp. jejuni infection in Korea has been reported in 1981, but the epidemiological information was lacking at the report. Therefore this study was undertaken to determine the Campylobacter carrier rate of the healthy Korean and of the Korean chicknens, and the antimicrobial susceptibity of the isolates from chicken. 129 stool samples from man and 296 fecal samples from chicken were collected and screened to determine the rates of Campylobacter carrier. Forty-four chicken isolates from Seoul and 30 chicken isolates from Iri city were examined the antimicrobial susceptibility. 1. The carrier rate in were examined the antimicrobial susceptibility 2. The isolation rates of the Campylobacter from Iri chickens were 50.3%. The highest rate was 76.3% on February and July, while the lowest rate ws 20.7% on March. 3. All of chicken isolates from Seoul and Iri were susceptible to amikacin and chromphenicol. 63.3% of the Seoul samples showed resistant to erythromycin.
