【摘要】 作者报道了一起幼儿园内空肠弯曲菌高感染的传播。该幼儿园儿童空肠弯曲菌阳性率为23.0％(43/187)。腹泻病例空肠弯曲菌阳性率为18.6％(8/43),健康儿童带菌率为24.3％(35/144)。同期另一幼儿园健康儿童和门诊非腹泻患儿带菌率分别为11.3％(27/238)和7.5％(15/201),三者间差异显著(P<0.005)。通过流行病学调查及菌株的生物分型表明,传染源可能是两名患空肠弯曲菌肠炎的炊事员,他们与儿童的菌株为同一生物型。其传播可能是通过污染的食物或人与人接触而引起的。更多还原

【Abstract】 An epidemiologic survey on Campylo-bacter jejuni infection in a nursery wasmade in April 1987. It was found that therewas a spread of C. jejuni high infection.Two cooks affected by enteritis of C. jejuniwere considered to be a reservoir of theinfection. Stool cultures were positive forC. jejuni in 43 out of 187 children, with apositive rate of 23%. Eight of the 43 haddiarrhea and the others were asymptomaticcarriers (24.3%). Controls were set up inanother nursery with 238 healthy childrenand 201 nondiarrheal outpatients;C. jejuniwas positive for 11.4% and 7.5%, respec-tively. The difference was quite significant(P<0.005). Results of biotyping on the strains iso-lated from the two cooks and the cnildrenin the nursery showed that all were of C.jejuni biotype 1, except two (4.7%) of thestrains from the children, which were C.coli. The authors have suggested thattransmission of C. jejuni in the nurserymay be caused by contaminated food orperson-to-person contact.更多还原
