title: Haemagglutinating, adhesive and physico-chemical surface properties of different Yersinia enterocolitica and Yersinia enterocolitica-like bacteria.
abstract: Fourteen strains of Yersinia enterocolitica, two strains of Yersinia kristensenii and one strain of Yersinia frederiksenii were investigated for haemagglutination, association with cultured cells, motility and physico-chemical surface properties. Three of the Y. enterocolitica strains, both Y. kristensenii and the Y. frederiksenii strain caused haemagglutination. Y. enterocolitica O-serotype 3 had the greatest tendency to associate with cultured cells. No correlation was seen between association and haemagglutination or motility. Bacterial cytotoxicity towards cultured cells was lost and haemagglutination acquired after repeated subcultivation. haemagglutinating strains were more hydrophobic than non-haemagglutinating strains. These results indicate that the bacterial surface structures, probably fimbriae, conferring bacterial haemagglutinating properties, are hydrophobic.
