Abstract
In animal feeds, concentrations of phytochemicals and organic acids are probably not lethal to pathogens. However, previous studies have shown that sub-lethal concentrations of cinnamaldehyde, carvacrol and certain acids inhibit attachment and invasion of bacterial pathogens into IPEC-J2 cells. The aim of this study was to investigate the effects of cinnamaldehyde and organic acids on selected immune related genes in porcine jejunum epithelial (IPEC-J2) cells when exposed to S. Typhimurium or E. coli K88 to find out whether such effects could contribute to the previously observed reduction of virulence.
