Nosocomial Pseudomonas aeruginosa Urinary Tract Infections

An outbreak of Pseudomonas aeruginosa urinary tract infections following cystoscopy traceable to a malfunctioning drying cabinet

“…P. aeruginosa is an important bacterial pathogen, particularly as a cause of nosocomial infections in hospitalized patients. Several outbreaks of P. aeruginosa caused by contaminated endoscopes have been reported [ [5] , [6] , [7] ]. Disinfecting scopes contaminated with P. aeruginosa can be challenging because of the ability of the bacteria to produce an exopolysaccharide biofilm that protects it from surfactant containing detergents [ 10 ].…”

“…P. aeruginosa is responsible for 11–23% of nosocomial infections worldwide [ 4 ]. Several outbreaks of P. aeruginosa caused by contaminated endoscopes have been reported [ [5] , [6] , [7] ]. The incidence of urinary tract infections (UTI) after flexible cystoscopy ranges from 2 to 21.2% [ 8 ].…”

A nosocomial epidemic ofSerratia liquefaciens urinary tract infection after cystometry

“…Rutala and co.workers (9) described art outbreak of UTI caused by Serratia rnarcescens which probably originated from infected urine containers and urometers, since routine disinfection ended the epidemic. A small percentage of nosocomial UTI results from other forms of urologic manipulation and even more rarely the use of incorrectly disinfected material (10,11) is the origin. Our epidemic was caused by the improper reuse of a disposable dome for monitoring pressure during cystometry.…”

An outbreak of carbapenem-resistant Pseudomonas aeruginosa in a urology ward

“…Careful evaluation for genitourinary tract infection before instrumentation, treatment of infection, appropriate disinfection of equipment, and thorough application of aseptic measures are mandatory when carrying out urologic instrumentation. Potential exogenous sources of organisms that can cause urologic surgery‐associated infections include contaminated irrigating or disinfectant fluid [4], contaminated instruments [5,6] and contamination inside the operating room [7–9].…”
