Food prepared for intensive care patients was frequently contaminated with Klebsiella species. Sixty-eight per cent of nasogastric feeds were contaminated with up to 10(4) klebsiellae per ml. Hospital kitchens were the source of contamination. Three patients ingested klebsiellae and subsequently excreted the same serotype in their faeces. Over a four-week period there was a correlation between kitchen, food, faecal, and clinical serotypes of klebsiellae. Serotypes ingested by intensive care patients occurred more frequently in clinical isolates from intensive care patients than from other hospital patients. Patients often acquired a food strain that had been ingested by another patient on the same ward.
为重症监护患者准备的食物经常被克雷伯菌属污染。68%的鼻饲食物每毫升被污染的克雷伯菌多达10⁴ 个。医院厨房是污染源。三名患者摄入了克雷伯菌,随后在粪便中排出了相同的血清型。在四周的时间里,克雷伯菌的厨房、食物、粪便和临床血清型之间存在相关性。重症监护患者摄入的血清型在重症监护患者的临床分离株中比在其他医院患者中更频繁出现。患者经常获得同一病房另一名患者摄入过的食物菌株。
