  • Title: Streptococcus uberis acquires plasmin activity following growth in the presence of bovine plasminogen through the action of its specific plasminogen activator.
    Author: Leigh JA, Lincoln RA.
    Journal: FEMS Microbiol Lett; 1997 Sep 01; 154(1):123-9. PubMed ID: 9297830.
    Abstract:
    Three (0140J, C197C and EF20) out of four strains of Streptococcus uberis exhibited high levels of bound plasmin activity following growth in the presence of bovine plasminogen. The remaining strain (C197) bound considerably less plasmin following growth in the same medium. In contrast to the others, this strain was unable to activate bovine plasminogen. Following growth of strain C197 in the presence of bovine plasminogen and a source of plasminogen activator (urokinase or culture filtrate from strain 0140J) high levels of bacterially associated plasmin were detected. None of the strains was able to activate human plasminogen and only trace levels of plasmin activity were detected in association with the S. uberis following growth in the presence of human plasminogen. All strains were able to bind plasmin activity following incubation in the presence of either bovine or human plasmin. However, in each case the level of activity detected following incubation in human plasmin was approximately five-fold less than that observed following incubation with bovine plasmin. None of the strains bound detectable levels of either human or bovine plasminogen. It is concluded that activation of plasminogen is required prior to binding of plasmin by S. uberis.
