  • Title: The nature of clotting and fibrinolytic activities of Bacteroids melaninogenicus.
    Author: Wegrzynowicz Z, Ko HJ, Pulverer G, Jeljaszewicz J.
    Journal: Zentralbl Bakteriol Orig A; 1978 Jan; 240(1):106-11. PubMed ID: 24965.
    Abstract:
    From the supernatant of B. melaninogenicus ss. asaccharolyticus culture, a protein fraction was isolated by ethanol precipitation. The fraction was tested for the presence of clotting and fibrinolytic activities by application of quantitative techniques and specific substrates for measurement of prothrombin and plasminogen activation, and collagenase and elastase activity. It is postulated that ability of Bacteroides melaninogenicus ss. asaccharolyticus extracellular factors to clot fibrinogen and activate plasminogen, are due to a limited proteolysis by the proteolytic enzymes produced by this microorganism and not to the existence of specific B. melaninogenicus coagulase of plasminogen activator.
