Hospital food was examined for the presence of Klebsiella species. Salads and cold meat were most frequently contaminated, often containing more than 10(3) organisms per g. Klebsiella species were also widely distributed in the kitchen environment which was considered, at least in part, to be the source of the organisms in food. By the use of serological and bacteriocin typing, intestinal carriage of strains ingested in food could be demonstrated.
对医院食物进行了克雷伯氏菌属检测。沙拉和冷盘受污染最为频繁,通常每克含有超过10³个微生物。克雷伯氏菌属在厨房环境中也广泛分布,这至少在一定程度上被认为是食物中微生物的来源。通过血清学和细菌素分型,可以证明食物中摄入的菌株在肠道中的携带情况。
