Preliminary studies of the effect of ozone on the bactericidal properties of complement.

The study analyzes the bactericidal influence of an ozonized blood serum on gram-negative bacilli. Considerable differences were observed concerning the effect which ozonized normal human serum has upon Klebsiella, Pseudomonas and Salmonella strains. It was found that the impact may vary depending not only on the time of the exposure of serum to ozone, but also on the type of strain and the structure of the outer membrane of the bacteria. The Salmonella typhimurium strain of the Ra chemotype treated with the serum which was exposed to ozone showed higher susceptibility to the action of complement than the S. typhimurium strain of the S chemotype.
