Campylobacteriosis is mainly caused by infection with Campylobacter jejuni following consumption or handling of Campylobacter-contaminated poultry meat. The aim of this study was to investigate the effect of probiotic Enterococcus faecium AL41 on TGF-β4 and IL-17 expression and on immunocompetent cell distribution after C. jejuni infection in broiler chicken, as a second part of the previous study of Karaffová et al. (2017). Accordingly, day-old chicks were randomly divided into four experimental groups of 10 chicks each (n = 10): control (C), E. faecium AL41 (EFAL41), C. jejuni CCM6191 (CJ), and combined E. faecium AL41 + C. jejuni CCM6191 (EFAL41 + CJ). Samples from the caecum were collected on days 4 and 7 post Campylobacter infection (dpi), for the isolation of mRNA of TGF-β4, IL-17 and for immunohistochemistry. The relative mRNA expression of TGF-β4 was upregulated in the combined (EFAL41 + CJ) group compared to other groups during both samplings, but the expression of IL-17 was downregulated. Similarly, the highest density of CD3+ was detected in the combined group at 7 dpi, but the number of IgA+ cells was increased in both groups with EFAL41. It was concluded that the EFAL41 probiotic E. faecium strain can modulate the expression of selected cytokines (upregulation of TGF-β4 but downregulation of IL-17 relative expression), and activate IgA-producing cells in the caeca of chicks infected with C. jejuni CCM6191.
