Molecular detection of lactose fermenting enteroinvasive Escherichia coli from patients with diarrhea in Tehran-Iran

摘要

Background and Objectives:Enteroinvasive Escherichia coli (EIEC) is one the cause of acute diarrhea and bacillary dysentery in developing countries. Routine diagnostic microbiology tests are not capable to distinguish EIEC from other pathogenic or non-pathogenic E. coli. PCR, targeting ipaH, virF, virB and other virulence genes, is a diagnostic method for detecting E. coli pathotypes. Using PCR, we identified EIEC by PCR targeting ipaH and virF genes among E.coli isolates from patients with diarrhea at the selected hospitals in Tehran.
