Hemolysins of Edwardsiella tarda.
Isolates of Edwardsiella tarda from four sources produced nonfilterable hemolsin in trypticase soy broth. The cell-associated hemolysin was partially heat labile, destroyed by formalin and sensitive to treatment with trypsin. These characteristics, and the observation that Ca++ or Mg++ ions enhanced activity, suggest that a proteinaceous, enzymic component may be responsible for the hemolytic activity.
