Klebsiella of capsular type K2 were investigated to find out whether a single epidemic clone was the source of many outbreaks of infection in different hospitals, in different areas over a period of five years. The klebsiellas studied were found to be very similar; they were of the same biotype, had similar klebecin sensitivity patterns and carried multiple drug-resistance plasmids; however, characterization of these plasmids showed that they were heterogeneous. Thus there was not a single epidemic bacterial clone.
对K2荚膜型肺炎克雷伯菌进行了调查，以确定单一的流行克隆是否是五年内不同地区不同医院多次感染暴发的源头。研究发现，所研究的肺炎克雷伯菌非常相似；它们属于同一生物型，具有相似的克雷伯菌素敏感性模式，并携带多重耐药质粒；然而，这些质粒的特征表明它们是异质的。因此，不存在单一的流行细菌克隆。
