Lack of correlation between the presence of plasmids and fimbriae in Yersinia enterocolitica and Yersinia pseudotuberculosis

S kurnik , M. 1984. Lack of correlation between the presence of plasmids and fimbriae in Yersinia enterocolitica and Yersinia pseudotuberculosis. Journal of Applied Bacteriology 56 , 355–363.
Thirty-nine strains of Yersinia enterocolitica and 10 strains of Yersinia pseudoluber-culosis were studied for the presence of fimbriae, plasmids and two plasmid associated phenotypic expressions, autoagglutination and Ca²⁺ dependent growth at 37C. All of the strains studied became fimbriated, which was confirmed by electron microscopy and haemagglutination tests. Fimbriation was not correlated with the presence or absence of plasmids.
