Abstract

|
As Pyocine type I of P seudonas aruginosa by the method of Giliies and Govan occupies a majority of strains typed, subtyping of Type I is necessary to increase the significance of pyocine typing in the epidemiology of Pseudomonas aeruginosa infections.
The author tried to type I strains isolated from various wound infections (general strain) and viginal cavities (vaginal strains) into subgroups. Strains used as indicator are 74 untypable strains of stock cultures.
Among indicators used, 37 strains were considered of no value since they were completely inhibited or resistant to all pyocine-producine strains.
Among rest of 37 indicators, 9 strains were resistant to all vaginal producer strains but inhibited by some general strains, and 4 strains were on the contrary inhibited by all vaginal strains but resistant to some general strains. The rest of 24 strains exhibited various patterns by producer strains. From 24 indicators, 5 strains were selected to formulate a subtyping pattern. With the formula general strains and vaginal strains can be subtyped, but still exhibited a significant differences between both groups in subtyped pyocine patterns.
