Proteus Mirabilis Articles

Proteus mirabilis is a major cause of catheter-associated urinary tract infection (CAUTI), emphasizing that novel strategies for targeting this bacterium are needed. Potential targets are P. mirabilis surface-associated swarming motility and the propensity of these bacteria to form biofilms that may lead to catheter blockage.

Urinary catheters have been used on an intermittent or indwelling basis for centuries, in order to relieve urinary retention and incontinence. Nevertheless, the use of urinary catheters in the clinical setting is fraught with complication, the most common of which is the development of nosocomial urinary tract infections, known as catheter-associated urinary tract infections.

Proteus mirabilis is a model organism for urease-producing uropathogens. These diverse bacteria cause infection stones in the urinary tract and form crystalline biofilms on indwelling urinary catheters, frequently leading to polymicrobial infection.

Uncomplicated urinary tract infections, especially those caused by Escherichia coli, have historically been widely studied. However, complicated urinary tract infections are presenting ever increasing healthcare challenges, particularly with Proteus mirabilis.

Catheter-associated urinary tract infections (CAUTI) caused by Proteus mirabilis are very difficult to treat due to the ability of biofilm formation and drug resistance of these bacteria. The aim of this study was to assess the antibiofilm activity of phages and develop phage cocktail to combat biofilm of P.
