Abstract
Collagenase enzyme activity of 38 Pseudomonas aeruginosa strains and 38 strains of Escherichia coli from various pathological sources was measured by a simple method. This method uses plates with collagen gel. The rate of gel lysis is proportional to the collagenase concentration. The method is simple and requires no special materials or equipment. From the 38 P. aeruginosa strains, 34 were collagenase positive. All 38 strains of E. coli were collagenase negative.
