The Effects of Flavomycin and Colistin Sulfate Pre-Treatment on Ileal Bacterial Community Composition, the Response to Salmonella typhimurium and Host Gene Expression in Broiler Chickens

Abstract: The composition of the bacterial community affects the intestinal health and growth performance of broiler chickens. The main purpose of this study was to explore the effects of flavomycin and colistin sulfate on the resistance to Salmonella typhimurium infection, ileal bacteria and intestinal health. In total, 396 1-day-old broiler chickens were randomly divided into six groups. Two groups were fed each one of the diets—the control diet (CON), the flavomycin at 10 mg/kg diet (AntiG+), and the colistin sulfate… Show more

“…In this study, the challenge with S. Typhimurium significantly reduced the diversity of the intestinal bacterial community. It was shown that S. Typhimurium infection in the early stage can significantly inhibit the growth of other gut microbes and reduce the diversity of the community ( He et al., 2019 ). Highly nutritious diets can significantly increase diversity indexes, indicating that high levels of nutrition can maintain intestinal health.…”

“…At the same time, Salmonella infection induced the inflammatory expressions of NF-κB and MyD88 genes and decreased the expressions of claudin-1, occludin, and mucin-2 tight junction genes in the intestines. Furthermore, S. Typhimurium was reported to significantly decrease ileal bacterial diversity indices [ 278 , 279 ]. The invasion plasmid antigen J (IpaJ) from Salmonella Pullorum was reported to suppress NF-κB activation by inhibiting IκBα ubiquitination and modulating the subsequent inflammatory response [ 280 ].…”

“…The intestinal crypts mainly secreted digestive enzymes, and the crypts became shallower in depth after differentiation and maturation. Increasing the V/C was benefit to improve intestinal function [ 11 ]. In our study, the antibiotics reduced feed conversion mainly by increasing intestinal secretion.…”

“…Previous studies have shown that adding probiotic in a non-pathological state did not significantly improve the diversity of intestinal microbiota and the steady state of the intestinal environment, which was consistent with this results [ 45 , 46 ]. Bacteroidetes and Firmicutes have been reported to be the main dominant bacteria in the gut of poultry [ 11 ]. In this study, E. faecium PNC01 increased the relative abundance of Firmicutes, which can promote host energy metabolism.…”
