Inhibition of Pseudomonas aeruginosa by Hyperbaric Oxygen II. Ultrastructural Changes

Inhibition of Pseudomonas aeruginosa by hyperbaric oxygen. II. Ultrastructural changes.

The ultrastructure of Pseudomonas aeruginosa cells treated with hyperbaric oxygen for 20 to 24 hr was examined by electron microscopy. A marked difference in the morphology of the nuclear area and cytoplasm of experimental cells was noted when compared to control cells grown under normobaric conditions. This difference was characterized by the absence of a definitive nuclear area and a reduced ...

Hyperbaric Oxygen Sensitizes Anoxic Pseudomonas aeruginosa Biofilm to Ciprofloxacin

Chronic Pseudomonas aeruginosa lung infection is characterized by the presence of endobronchial antibiotic-tolerant biofilm, which is subject to strong oxygen (O2) depletion due to the activity of surrounding polymorphonuclear leukocytes. The exact mechanisms affecting the antibiotic susceptibility of biofilms remain unclear, but accumulating evidence suggests that the efficacy of several bacte...

Growth inhibition of Pseudomonas aeruginosa by valine.

Inhibition of Pseudomonas aeruginosa biofilm formation by 2,2’-bipyridyl, lipoic, kojic and picolinic acids

Objective(s):The inhibitory effects of iron chelators, and FeCl3 chelation on biofilm formation and swarming motility were investigated against an opportunistic human pathogen Pseudomonas aeruginosa. Materials and Methods:The inhibitory activity of 2,2’-bipyridyl, lipoic acid, kojic acid and picolinic acidonbiofilm formation of P. aeruginosa strain PAO1 and three clinical isolates (P. aeruginos...
