The adhesive properties of bacteria of intestinal origin

Differences between strains of nonpathogenic Escherichia and lactobacilli, as well as some pathogenic bacteria of enteric origin (Escherichia, Shigella, Campylobacter), in their capacity to adhesion to rat enteric and colonic cells have been shown in vitro. The strains under study have been found to...

Summary:Differences between strains of nonpathogenic Escherichia and lactobacilli, as well as some pathogenic bacteria of enteric origin (Escherichia, Shigella, Campylobacter), in their capacity to adhesion to rat enteric and colonic cells have been shown in vitro. The strains under study have been found to possess more pronounced adhesiveness with respect to colonic cells, which is indicative of their higher receptive capacity in comparison with enteric cells. In the absence of normal microflora lactobacilli and Escherichia exhibit increased adhesiveness with respect to enteric cells. Escherichia enterotoxigenic strains, Yersinia enterocolitica and Salmonella typhimurium virulent strains, Campylobacter jejuni clinical isolates possess more pronounced capacity for adhesion to enteric cells of Peyer's plaques than to other types of epithelial cells, which may be of importance in the pathogenesis of these infections.
