These isolates do not react with any of the current\n                    <jats:italic>Shigella<\/jats:italic>\n                    antisera including all existing and provisional serotypes. Among these SLOs, a unique cluster of seven isolates with an identical plasmid profile was found and these isolates were further characterized by phenotypic and genotypic techniques. All were nonlactose fermenters, with an identical biochemical pattern typical of\n                    <jats:italic>Shigella dysenteriae<\/jats:italic>\n                    . They were classified as invasive since they harboured the 140 MDa invasive plasmid, were able to bind Congo red, produced keratoconjunctivitis in the guinea pig eye, and were positive by PCR for the\n                    <jats:italic>ipaH<\/jats:italic>\n                    gene and\n                    <jats:italic>Shigella<\/jats:italic>\n                    enterotoxin 2 [ShET-2] gene. All isolates were resistant to ampicillin, tetracycline and sulfamethoxazole\u2013trimethoprim but were susceptible to mecillinam, nalidixic acid, ceftriaxone and ciprofloxacin. Six of the isolates were identical in DNA pattern by PFGE with the seventh exhibiting a closely related pattern; both patterns were distinguishable from all other\n                    <jats:italic>Shigella<\/jats:italic>\n                    and\n                    <jats:italic>Escherichia coli<\/jats:italic>\n                    patterns. An antiserum prepared against one of the isolates reacted with all isolates and did not cross-react with other\n                    <jats:italic>Shigella<\/jats:italic>\n                    and\n                    <jats:italic>E. coli<\/jats:italic>\n                    serotype reference strains.
