Virulence factors inProteusbacteria from biofilm communities of catheter-associated urinary tract infections

Prevention of Catheter-Associated Urinary Tract Infections

Urinary catheter placement is an extremely common medical intervention. It can be used either temporarily, for example to drain a full bladder, to monitor urine output or it can be indwelling for long term drainage. While urinary catheters are a safe medical practice, complications can and do arise from their use and can be a source of morbidity for hospital or nursing home residents. The term ...

[Prevention of Catheter-Associated Urinary Tract Infections].

With a share of 22.4%, nosocomial urinary tract infections (nUTIs) are among the most frequent infections acquired in hospitals, along with surgical site infections (24.7%), pneumonia (21.5%), clostridium difficile infections (6.6%) and primary sepsis (6%) 1. 80% of all nUTIs are associated with indwelling urinary catheters, with 12-16% of all hospitalised patients and up to 81.8% of all intens...

Role of biofilm in catheter-associated urinary tract infection.

The predominant form of life for the majority of microorganisms in any hydrated biologic system is a cooperative community termed a "biofilm." A biofilm on an indwelling urinary catheter consists of adherent microorganisms, their extracellular products, and host components deposited on the catheter. The biofilm mode of life conveys a survival advantage to the microorganisms associated with it a...

Virulence-associated factors in Escherichia coli strains isolated from urinary tract infections

Escherichia coli is one of the most frequent causes of extra-intestinal diseases including urinary tract infections (UTI). E.coli is the most frequent urinary pathogen isolated from 50% 90% of all uncomplicated urinary tract infections. (Steadman and, Topley, 1998). It is now recognized that there are subsets of faecal E. coli , which can colonize periurethral area, enter urinary tract and caus...
