Examination of biofilm formation and risk of infection associated with the use of urinary catheters with leg bags

The Journal of Hospital Infection
J RogersCharles W Keevil

Abstract

Urinary catheters and legs bags were simultaneously colonized by Escherichia coli and Proteus vulgaris using a model urinary drainage system. the system was continuously supplied with filter-sterilized artificial urine using a diurnal flow pattern. The extent of colonization was determined by assessment of both planktonic and biofilm formation over time. Contamination of the catheters resulted in rapid colonization of the whole system within a 24 h period. Contamination of the leg bags resulted in an ascending biofilm formation over a four-day period. Results indicated that infection risk could be minimized by changing the catheter and leg bags at least once a week. The design of the leg bags was not found to influence the rate or extent of biofilm formation.

Biofilm & Infectious Disease

Biofilm formation is a key virulence factor for a wide range of microorganisms that cause chronic infections.Here is the latest research on biofilm and infectious diseases.

Biofilms

Biofilms are adherent bacterial communities embedded in a polymer matrix and can cause persistent human infections that are highly resistant to antibiotics. Discover the latest research on Biofilms here.
