TGFB1 and Salmonella Infections: In the challenge experiment, a slight increase in Salmonella shedding was observed in response to pig transfer to the grower houses, regrouping and experimental re-infection with S. Typhimurium.  ANE supplementation had no effect on Salmonella counts; nevertheless, it reduced Enterobacteriaceae counts, as well as the expression of the inflammatory IL22 and TGFB1 which are associated with colonisation and persistent Salmonella infection.
