The Identification of Atypical Strains of Pseudomonas aeruginosa

Abstract

The diversity of colonial types of Pseudomonas aeruginosa which may be encountered is described, together with a series of biochemical tests and the application of serological and pyocine typing which are of use in identifying atypical strains. These methods are particularly recommended for strains which do not form pigment. It is suggested that absence of pigment production even on special media does not preclude the possibility that a strain is P. aeruginosa.
