Providencia stuartii nosocomial urinary tract infections occurring in the same hospital over an 18-month period of retrospective study were shown, by serotyping and biotyping, to have been caused by two endemic strains. Two episodes, involving 38 patients in one ward and 11 patients in another, were caused by a mannitol-positive strain of serotype O55. Transmission of the strain through the movements of one patient appeared to have been the basis for the introduction of the agent from one ward to the other. In another episode, involving two patients in a third ward, the infections were caused by a mannitol-negative strain of serotype O49. The study demonstrated the usefulness of serotyping and biotyping in epidemiological studies of infections caused by P. stuartii.
在一项为期18个月的回顾性研究中,通过血清分型和生物分型发现,同一医院内发生的斯氏普罗威登斯菌医院获得性尿路感染是由两种地方流行菌株引起的。其中两起感染事件,一起涉及一个病房的38名患者,另一起涉及另一个病房的11名患者,是由血清型O55的甘露醇阳性菌株引起的。该菌株似乎通过一名患者的活动传播,成为该病原体从一个病房传播到另一个病房的原因。在第三起感染事件中,涉及第三个病房的两名患者,感染是由血清型O49的甘露醇阴性菌株引起的。该研究证明了血清分型和生物分型在斯氏普罗威登斯菌所致感染的流行病学研究中的有用性。
