Mycoplasma species bovine group 7 bound plasminogen at the cell surface in a lysine-dependent manner. Cell-bound plasminogen was rapidly activated to plasmin by exogenous urokinase, and this activity was associated with plasminogen binding capacity. Binding assays using plasminogen modified with a trifunctional cross-linking agent revealed several binding proteins.

Bovine Non-O157 Shiga Toxin 2-Containing Escherichia Coli Isolates Commonly Possess Stx2-Edl933 And/Or Stx2vhb Subtypes, Kim Brett, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven Djordjevic Jan 2003

Bovine Non-O157 Shiga Toxin 2-Containing Escherichia Coli Isolates Commonly Possess Stx2-Edl933 And/Or Stx2vhb Subtypes, Kim Brett, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven Djordjevic

stx2 genes from 138 Shiga toxin-producing Escherichia coli (STEC) isolates, of which 127 were of bovine origin (58 serotypes) and 11 of human origin (one serotype; O113:H21), were subtyped. The bovine STEC isolates from Australian cattle carried ehxA and/or eaeA and predominantly possessed stx2-EDL933 (103 of 127; 81.1%) either in combination with stx2vhb (32 of 127; 25.2%) or on its own (52 of 127; 40.4%). Of 22 (90.9%) bovine isolates of serotype O113:H21, a serotype increasingly recovered from patients with hemolytic uremic syndrome (HUS) or hemorrhagic colitis, 20 contained both stx2-EDL933 and stx2vhb; 2 …
