Sink drains have long been known to harbour pathogenic bacteria and efforts such as heated sink traps have been made to control them. Sink outlet pipes have been implicated in outbreaks of infection by multi-resistant Klebsiella pneumoniae. To investigate whether a change to copper pipes might prevent cross-infection, sections of standard sink outlet pipe were left in containers of water to which multi-resistant human strains of K. pneumoniae had been added. Bacterial counts from the water of containers to which copper pipe had been added were lower than those from containers to which PVC (polyvinyl chloride) pipe had been added.
长期以来，人们都知道水槽排水口藏有致病细菌，并且已经采取了诸如加热水槽存水弯等措施来控制这些细菌。水槽出口管道与多重耐药肺炎克雷伯菌感染的爆发有关。为了研究更换为铜管是否可以预防交叉感染，将标准水槽出口管道的部分样本放置在添加了多重耐药肺炎克雷伯菌人类菌株的水中。添加铜管的容器中的水样细菌计数低于添加PVC（聚氯乙烯）管的容器中的水样细菌计数。
