Abstract:
Up to now enteroinvasive Escherichia coli (EIEC) has not been extensively studied for toxin production. We have investigated 15 EIEC strains belonging to ten representative serotypes (O28ac:H-, 029:H-, O112ac:H-, O124:H-, O136:H-, O143:H-, O144:H-, O152:H-, O164:H- and O167:H-) for their ability to produce enterotoxins (LT and STa), Shiga-like toxins (SLT-I and SLT-II), cytotoxic necrotizing factors (CNF1 and CNF2) and other toxic products with necrotic or lethal activity. None of these strains were toxigenic.
