An outbreak of diarrhoea due to Salmonella worthington in five newborn babies, 5 weeks after a similar outbreak in 13 babies for which no cause had been found, occurred in the nursery of a maternity ward. The source of infection was traced to the contaminated rubber tubing of a mechanical suction apparatus. S. worthington was isolated from the rubber tubing and the Y connexion of the suction apparatus from which all the five infected babies had received suction. Reflux of contaminated amniotic fluid into the sterile catheter connected to the apparatus some time before use could have been the means of introducing the infected material to the oropharynx of the newborn babies, and amniotic fluid, acting as a good medium to support the growth of S. worthington, might be responsible for the long-lasting contamination.
在一家产科病房的新生儿护理室里，13名婴儿曾爆发过一次腹泻疫情，但未找到病因。5周后，又有5名新生儿因沃辛顿沙门氏菌感染而腹泻。感染源被追溯到一台机械吸引装置被污染的橡胶管。从橡胶管以及吸引装置的Y形接头处分离出了沃辛顿沙门氏菌，所有5名受感染婴儿都曾通过该装置接受吸引。在使用前的某个时候，受污染的羊水回流到与该装置相连的无菌导管中，这可能是将感染物质引入新生儿口腔的途径，而羊水作为支持沃辛顿沙门氏菌生长的良好培养基，可能是造成长期污染的原因。
