Detection of Fibrinolytic and Elastase Activity Among Clinical Isolates of Serratia Marcescens

Abstract
Thirty-three of 35 clinical isolates of Serratia marcescens examined displayed fibrinolytic activity, whereas only 5 isolates elaborated a weakly active elastase. All strains liquefied gelatin, hydrolyzed DNA, produced lipases and a lecithinase, but none revealed hyaluronidase or collagenase activity. Twenty-one, 16, and 30 of the isolates hemolyzed sheep, rabbit, and human erythrocytes, respectively.
