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 species. Under the electron microscope MR fimbriae of Edwardsiella were found to be thicker than MS fimbriae (6.5 nm and 6.0 nm respectively). MS fimbriae of Levinea had 6.5 nm in diameter.
