Abstract:
A cell-associated mannose-resistant hemagglutinating factor (HAF) was extracted from enteroinvasive Escherichia coli (EIEC) serotype O124:H- by sonication. Ultrastructural analysis of EIEC and immunocytochemical assays with the cell-free HAF and EIEC bacterial cells on HeLa cells, suggested that the HAF is a non-fimbrial putative adhesive factor that mediates in vivo adherence of EIEC to human epithelial cells.
