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 granularity of the cytoplasm.
