title: Two new Escherichia coli O groups: O172 from "Shiga-like" toxin II-producing strains (EHEC) and O173 from enteroinvasive E. coli (EIEC).
abstract: Two Escherichia coli strains were established as antigenic test strains for two new O groups, O172 and O173. The O172 strain (EHEC) which produces "Shiga-like" toxin II (verocytotoxin 2) was isolated from a case of haemorrhagic colitis while the enteroinvasive O173 strain (EIEC) originated from a child with diarrhoea.
