To determine the utility of available Pseudomonas cepacia typing systems for confirming the relatedness of isolates, we applied these methods to isolates associated with previously investigated nosocomial outbreaks. We compared chromosome analysis, serologic reactions, biochemical tests, bacteriocin production and susceptibility, and antimicrobial susceptibility in their ability to determine outbreak relatedness. Chromosome analysis, serologic reactions, and biochemical tests were each demonstrated to be epidemiologically useful methods for typing isolates. Determination of the sensitivity and specificity of these typing techniques will facilitate their application in the epidemiologic study of this increasingly important nosocomial pathogen.

[Double-blind study on the long-lasting improvement of physical endurance following oxygen-multistep-therapy].

The characteristic of Oxygen Multistep Therapy is the long-lasting improvement of the energetic or oxygenation state of the organism. This specific effect is confirmed with statistical significance by a two-centric double-blind study on 20 male healthy volunteers from the working population. In this study the ergometrically measurable increase of physical fitness, which was determined two weeks after performance of two 15 min-oxygen-multistep-quick processes, served as over-all criterion. The mean value of the continuing elevation was 17%. On individuals having initially lower physical capacities and therefore being particularly in need of treatment, increases of 25, 33, and even 45% were determined.
