Cytolethal distending toxin (CLDT) production was found in three (2.8%) strains belonging to serotype 086:H34, while one O11 lab:NM strain hybridized with a SLT-II probe but did not express any cytotoxic activity. All four strains showed localized adherence to HeLa cells and hybridized to an E. coli attaching\u2013effacing gene (eae) probe. The CLDT-producing strains had multiple plasmids and some were present in all strains, including a plasmid of ~54\u2002MDa that hybridized with the EAF probe.Key words: enteropathogenic Escherichia coli, EPEC adherence factor sequences, Shiga-like toxin, cytolethal distending toxin. <\/jats:p>","DOI":"10.1139\/m94-056","type":"journal-article","created":{"date-parts":[[2010,2,2]],"date-time":"2010-02-02T12:14:27Z","timestamp":1265112867000},"page":"341-344","source":"Crossref","is-referenced-by-count":19,"title":["Survey of cytotoxin production among Escherichia coli strains characterized as enteropathogenic (EPEC) by serotyping and presence of EPEC adherence factor (EAF) sequences"],"prefix":"10.1139","volume":"40","author":[{"given":"Beatriz E.
