Campylobacter장염에 대한 역학적 연구 1. 사람, 동물, 식품 및 강물에 있어서 campylobacter jejuni의 분포와 분리주의 혈청형

Epidemiological studies on compylobacter enteritis in Korea 1. Prevalence of Campylobacter jejuni and C. coli in Human, Animals, Food and Water and Serotypes Isolated

To investigate the epidemiological trait of gastroenteritis of human caused by C. jejuni, isolation of etiological agent was carried out. Isolated C. jejuni were biotyped and serotyped. A total of 1929 specimens from 438 human, 182 milking cows, 200 cattle, 187 goats, 70 dogs, 426 pigs, 278 chickens, 148 duck, 50 raw milk, 110 chicken meat, 20 duck liver and 50 river water was examined for the presence of C. jejuni and C. coli by direct plating and enrichment techniques. Isolation rates detected in humnan, amimals food and water were as follows: human 0.7%, ducks 54.7%, dogs 37.1%, chickens 33.7%, goats 26.7%, cattle 25.5%, pigs 19.9% and milking cows 7.7%. The organism was isolated from 65% of 20 duck livers and from 20% of 110 chicken mest. Campylobacter was not recovered from raw miver water. The majority of the isolated 201 strains of C. jejuni was classified as biotype Ⅰ(53.7%) and biotype Ⅱ(36.8%), 117 strains of C.coli were 59.8% of biotype Ⅰ, 40.1% biotype Ⅱ. Isolated C. jejuni stranis showed 13 different serotype, and serotype 4, 5, 26 and 36 were most frequent, C. Coli strains howed 7 different serotype, and serotype 21, 25 and 29 were relatively commom.
