Twenty-four per cent of 2315 patients admitted to the intensive care unit of St Thomas's Hospital in the 4 year period from November 1969 became colonized or infected with Klebsiella species. Capsular typing of 986 klebsiella isolates from 551 patients showed that there were 695 patient-isolates, mostly derived from the respiratory tract. Capsular types 47 and 21 were the commonest types and together accounted for 19.9% of the patient-isolates. The 14 commonest types accounted for 47.3% of all patient-isolates and all these strains showed clustering, strongly suggesting a changing common source, cross infection, or both.
在1969年11月起的4年时间里,入住圣托马斯医院重症监护病房的2315名患者中,有24%的患者被克雷伯菌属定植或感染。对来自551名患者的986株克雷伯菌分离株进行荚膜分型,结果显示有695株患者分离株,大多来自呼吸道。荚膜47型和21型是最常见的类型,共占患者分离株的19.9%。14种最常见的类型占所有患者分离株的47.3%,所有这些菌株都呈现聚集性,强烈提示存在不断变化的共同来源、交叉感染,或两者皆有。
