Sixty-six hospitalized patients became infected with a single strain of multiply resistant Pseudomonas aeruginosa over a 22-month period. The catheterized urinary tract was the site of the infection in 59 patients (89%). The outbreak was confined to a urology ward until an infected patient from this ward spent 2 weeks in the surgical intensive care unit (SICU). Subsequently patients who acquired the infection in the SICU were discharged to surgical wards throughout the hospital. Urine measuring containers and urometers used in the SICU were the reservoir of the P. aeruginosa; daily sterilization of this equipment terminated the outbreak. Urometers appeared to be the reservoir of the epidemic strain in subsequent outbreaks. Five patients were still infected when they were readmitted 3 to 12 months after the first admission, and therefore represented an additional reservoir of infection.
在22个月的时间里，66名住院患者感染了单一菌株的多重耐药铜绿假单胞菌。59名患者（89%）的感染部位是导尿管相关的泌尿道。此次暴发局限于泌尿外科病房，直到该病房的一名感染患者在外科重症监护病房（SICU）住了2周。随后，在SICU获得感染的患者被转到医院的各个外科病房。SICU使用的尿液量杯和尿量计是铜绿假单胞菌的储存源；对该设备进行每日消毒后暴发终止。在随后的暴发中，尿量计似乎是流行菌株的储存源。5名患者在首次入院3至12个月后再次入院时仍处于感染状态，因此构成了额外的感染源。
