The foodborne mycotoxin deoxynivalenol (DON) produced by species threats animal and human health through disruption of the intestinal barrier. Targeting the gut microbiota and its products appears as a promising strategy to mitigate DON intestinal toxicity. In this study, we investigated whether the bacterial metabolite butyrate could alleviate epithelial barrier disruption induced by DON.

Coprophagia by suckling rabbits, i.e. ingestion of feces from their mother, reduces mortality after weaning.

The gut microbiota plays a key role in the postnatal development of the intestinal epithelium. However, the bacterial members of the primocolonizing microbiota driving these effects are not fully identified and the mechanisms underlying their long-term influence on epithelial homeostasis remain poorly described. Here, we used a model of newborn piglets treated during the first week of life with the antibiotic colistin in order to deplete specific gram-negative bacteria that are transiently dominant in the neonatal gut microbiota.

Postweaning diarrhea (PWD) in piglets impair welfare, induce economic losses and lead to overuse of antibiotics. The early life gut microbiota was proposed to contribute to the susceptibility to PWD. The objective of our study was to evaluate in a large cohort of 116 piglets raised in 2 separate farms whether the gut microbiota composition and functions during the suckling period were associated with the later development of PWD.

Intestinal organoids are increasingly being used to study the gut epithelium for digestive disease modeling, or to investigate interactions with drugs, nutrients, metabolites, pathogens, and the microbiota. Methods to culture intestinal organoids are now available for multiple species, including pigs, which is a species of major interest both as a farm animal and as a translational model for humans, for example, to study zoonotic diseases. Here, we give an in-depth description of a procedure used to culture pig intestinal 3D organoids from frozen epithelial crypts.
