Laboratory Diagnosis of Pseudomonas aeruginosa Infections

Laboratory diagnosis of pseudomonal infection is based on isolation of P. aeruginosa from feces or other clinical speci-mens containing mixed microbial flora by culture on selective medium, such as cetrimide agar.

Laboratory Diagnosis

Laboratory diagnosis of pseudomonal infection is based on isolation of P. aeruginosa from feces or other clinical speci-mens containing mixed microbial flora by culture on selective medium, such as cetrimide agar. Since P. aeruginosa is frequently present as a contaminant in the clinical specimen, hence not a single isolation but repeated isolations are essential to confirm P. aeruginosa as the causative agent of condition.

 Identification of bacteria

Nonlactose-fermenting and beta-hemolytic green pigmented colonies (Color Photo 39), which are rapid oxidase positive, are identified by biochemical properties, production of pyocins, and susceptibility to phage typing, serotyping, and molecular typing.
