IgA gene expression and quantification of mucous IgA+, IgM+ and CD4+ lymphocytes in the cecum of chicks was studied by qRT-PCR, immunohistochemistry and flow cytometry. A total of 220 1-day-old Salmonella-free chicks of Cobb 500 were divided into four groups (n=55). Group 1 served as control (C), group 2 was pretreated with probiotic bacterial strain(More)
Probiotic bacteria are frequently used for prevention of bacterial infections of the gastrointestinal tract, but there are only limited studies on their efficacy against viral gut infections in animals. The aim of this study was to investigate the effect of probiotic Lactobacillus reuteri L26 BiocenolTM on the innate and adaptive immune responses in(More)
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(More)
The relative mRNA expression of IgA, TGF-β4, IL-17, and concentration of secretory IgA (sIgA) in small intestine of chickens pretreated with Enterococcus faecium AL41 and challenged with Salmonella Enteritidis PT4 were studied. Salmonella-free day-old chicks (40) Cobb 500 breed, were divided into four groups of 10 chicks each (n = 10): control (C), treated(More)
