In an outbreak of gastroenteritis affecting 43 people, cryptosporidium and campylobacter were isolated from stool specimens and in two cases dual infection was found. All the cases had drunk unboiled water from a private untreated water supply. Investigations revealed the carcasses of three lambs in a collection chamber connected with the water supply, and these, or run-off of slurry from surrounding fields, were the presumed source of contamination. Issues relating to the maintenance and monitoring of private water supplies are discussed. Problems with such supplies include old piping, proximity of livestock, inadequate knowledge of the layout and limited resources for monitoring and maintenance.
在一次影响43人的肠胃炎疫情中，从粪便标本中分离出了隐孢子虫和弯曲杆菌，有两例发现了双重感染。所有病例都饮用了来自私人未处理水源的生水。调查发现，与供水系统相连的集水室中有三只羔羊的尸体，推测这些尸体或周围田地的粪便径流是污染源。文中讨论了与私人供水维护和监测相关的问题。此类供水存在的问题包括管道陈旧、靠近牲畜、对布局了解不足以及监测和维护资源有限。
