title: Antagonistic effect of bacteriocin against urinary catheter associated Pseudomonas aeruginosa biofilm.
abstract: BACKGROUND
  Pseudomonas aeruginosa is a gram negative opportunistic bacteria causes several infections commonly colonize these devices and developing biofilms. Bacteria in biofilm can be up to 1,000 times more resistant to antibiotics than the same bacteria circulating in a planktonic state.
  
  
  METHODS
  A total of 10 isolates of Pseudomonas aeruginosa were isolated from catheter associated urinary tract infections. While carbenicillin was the most effective antibiotic, all isolates developed multidrug resistant. Both crude and purified bacteriocin showed marked inhibition activity against planktonic and biofilm of the highly resistant isolate P. aeruginosa P7.
  
  
  CONCLUSIONS
  Bacteriocin extracted from a locally isolated L. acidophilus has an anti P. aeruginosa biofilm activity also it can be used as a therapeutic agent after adequate in vivo experimentation.
