For the EIEC, there were 15 isolates comprising four serogroups: O28, O29, O124, and O136.
ETEC, EPEC, EIEC, and EHEC were defined as strains having the respective genes.
coli strains that are unable to produce attaching-effacing lesions, including ETEC and EIEC.
The emergence of ETEC and EIEC, which had readily identifiable virulence determinants at a time when EPEC did not, brought the pathogenicity of EPEC into question.
We report the findings of the investigations into these EIEC

In cooperation with the ministries of Electricity and Petroleum, a number of international oil companies operating in Egypt launched EIEC
to promote energy conservation.
We developed a single multiplex PCR reaction to detect ETEC, EPEC, EIEC
, and STEC, using specific previously described (4-6) or new primers (GIBCO-BRL, Gaithersburg, MD) for diverse virulence traits (Table 1).
