Enterotoxigenic Escherichia coli
Abstract
We reported that the yeast Sc (strain CNCM I-3856) modulates transcript and protein expressions involved in inflammation, recruitment and activation of immune cells in differentiated porcine intestinal epithelial IPEC-1 cells. We demonstrated that viable Sc inhibits the ETEC-induced expression of pr...

Abstract
Escherichia coli enterotoxigenic strains produce one or more toxins which action result in production of diarrhea in animals including Man. One of these toxins, STb, has been mainly associated with colibacillosis in swine. Although highly prevalent in pigs with diarrhea, a relation between STb and d...

Abstract
Colonization factor antigens (CFAs) are important virulence factors in enterotoxigenic Escherichia coli (ETEC). Using a multiplex PCR and RT-PCR, this study tested the presence of common colonization factor-encoding genes and their expression in 50 ETEC strains isolated from stool specimens. The sam...

Abstract
We used porcine monocytic-derived DC (MoDC) as a model system. The results in this study demonstrate that FcgammaRI, II and III mRNA is expressed by porcine MoDC. Furthermore, we show that FcgammaRII and III are expressed on the cell surface and that F4-IC are internalized by MoDC via FcgammaR. This...
