We investigated the presence of the gene of subtilase cytotoxin (SubAB), described in certain highly virulent verocytotoxigenic E. coli strains, in isolates from Argentina and its relation with other virulence factors. The gene subA was present in eae-negative strains mostly associated with saa, vt2 and ehxA genes.

Escherichia albertii occasionally causes food-borne outbreaks of gastroenteritis in humans; however, little is known about the vehicle of transmission. To screen retail chicken products for the presence of E. albertii, 104 retail chicken products were investigated. Portions of enrichment cultures that were PCR-positive for E. albertii (n=3) were sub-cultured on agar medium. Only 2 strains obtai...

dendritic cells (dcs) play an important role in induction of cellular immune responses. it seems that dcs that reside in different organs may be distinct in their ability to  induce immune responses. this study was done to address the differences between spleen and liver dcs in induction of immune response and/or tolerance. cd11c+  dcs were separated from the liver and spleen of c57bl/6 mice an...

TRAIL, the TNF-related apoptosis-inducing ligand, induces apoptosis of tumor cells, but not normal cells; the roles of TRAIL in nontransformed tissues are unknown. Using a soluble TRAIL receptor, we examined the consequences of TRAIL blockade in an animal model of multiple sclerosis. We found that chronic TRAIL blockade in mice exacerbated experimental autoimmune encephalomyelitis induced by my...

Both T(H)1 and T(H)17 lymphocytes are implicated in inducing EAE. In mice lacking IFNgamma, T(H)17 are assumed to be the subset responsible for inflammation induction. Here, we demonstrate that IFNgamma KO mice have two additional effector subsets, one that up-regulates T(H)17-associated pro-inflammatory genes, but does not make IL-17 protein, and a second that utilizes IL-12-related elements o...

Here, we report the draft genome sequence of Escherichia coli strain R811. This bacterium was isolated from the bloody stool sample of a common marmoset, and was categorized as enteropathogenic E. coli because it possessed eae.

The decision to establish a major annual conference was the crucial step in our development from the Working Group on Echocardiography of the ESC, ultimately into the EAE, and the Euroecho meeting remains the jewel in our crown. In Florence last December we had a record attendance of almost 2900 participants from 82 countries, including a record number from industry. More abstracts than ever be...
