fimbriae and haemagglutinating properties in edwardsiella and levinea.using the haemagglutinating procedure, the presence of fimbriae was revealed in all 34 edwardsiella strains tested and in 3 levinea strains out of 17 examined. the great majority of fimbriate edwardsiella strains caused haemagglutination of mr type; only two strains of edwardsiella and all fimbriate strains of levinea brought about haemagglutination of ms type. all the strains exhibited a similar spectrum of haemagglutinating activity when they were tested against red cells of various animal spe ...197770969
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.197934473
