Slime capsule and fimbriae on Salmonella typhimurium var. cop.--electron microscopic study.
On Salmonella typhimurium var. cop. we found, under special culture conditions, on the same cell simultaneously fimbriae and mucoid material which was histochemically identified as an acid mucopolysaccharide. Membrane vesicles or invaginations of the cytoplasmic membrane are mentioned as a possible place of the slime production and the function of the glycocalyx is discussed regarding tenacity, as a diffusion barrier and attachment factor.
