Four enteropathogenic Escherichia coli strains were studied with respect to their antibiotic resistance characters, plasmid patterns, toxin production and haemagglutination properties. Two of these strains showed multiple antibiotic resistance characters, although all possessed several plasmids of varying sizes. One of the strains DD‐41 showed the presence of a non‐fimbrial cell‐associated mannose‐resistant haemagglutinin (MRHA) which was encoded by a 70 MDa plasmid. Conjugation experiments demonstrated that this MRHA‐containing plasmid also coded for ampicillin and tetracycline resistance factors and was self‐transmissible.
