Enzyme profiling of pseudomonas aeruginosa strains isolated from clinical specimens received from Alexandria University Hospitals

ABSTRACT

In this study, fifty-five Ps. aeruginosa strains isolated from different clinical specimens were examined for their enzymatic activities [8 enzymes] by substrate plate assays. The correlation study revealed that protease and elastase activities were ore prevalent in systemic isolates than in isolates from other sources, which suggested that these factors may play an important role in the dissemination of Ps. aeruginosa from local or superficial sites. Therefore, enzyme profiles could permit the fingerprinting and differentiation of clinical strains from various sources and hold a promising mean for future follow up studies and epidemiological surveys as a cheap and stable typing technique
