Markers of well-characterized aggregative adherence plasmids, present in typical EAEC
strains, are aggregative adherence regulator gene aggR, anti-aggregative protein or dispersin gene aap, and empiric plasmid probe (CVD432) that represents part of the aat secretion system operon (6).
As shown in Table 1, ETEC was the most prevalent DE group isolated in patients, closely followed by EAEC
(only characterized in the Villahermosa study) and then by atypical EPEC (aEPEC [eaeA + bfp-]).
In contrast, both EAEC
and atypical (Bfp-negative) EPEC were identified in >5% of patients, and the difference between the symptomatic and baseline groups was significant for each of these pathotypes (Table 4).
DNA probes were obtained from cloned genes (bfpA, perA, E-hly, EAEC
, daaC, cdt, cnf, hly) (6) or by PCR amplification, which used as templates the genomic DNA of EAEC
prototype strains O42 (aafC, aggR, aspU, shf irp2, pet, and pic) and 17-2 (aggC and astA); extraintestinal pathogenic strains (ExPEC) J96 (pap) and KS52 (afa), and E.
Other possible trade partners may be India, Egypt, Singapore, Serbia and Israel with whom EAEC
has been conducting intensive negotiations.
We have also arranged for several of these companies to pitch at the European Commission pavilion at the convention., said Blandine Chantepie-Kari, VP University & Entrepreneurship Soft Landing Programs of the ENRICH in the USA partner EAEC
) strains, can also occur in other pathovars such as ETEC, EPEC, and EHEC, and has been identified in strains of E.
coli (DEC) pathotypes, ETEC 7 (3.0%), EAEC
13 (5.5%) and atypical EPEC 2 (0.8%) were detected.
The distribution of 42 DEC pathotype isolates were: EPEC was found in 19 (45.3%), EAEC
in 17(40.5%), ETEC in 3 (7.1%), EIEC in 3 (7.1%) and 0 (0%) in STEC and controls.
Nearly 70 percent of Russia's exports to and 30 percent of its imports from the other members of the Eurasian Economic Community (EAEC
) are done in Russian ruble, he said.
