Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Full frame distilled prediction
Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Abstract
Salmonella Enteritidis is a pathogen, which can infect humans and chickens. This study was designed to address the impact of two potential prebiotics, mannanoligosaccharides (MOS) and xylooligosaccharides (XOS), on the caecal microbiota and expression of cytokines in chickens infected with S. Enteritidis. Newly hatched chicks were assigned to one of five groups: (1) uninfected control, (2) infected control, (3) infected + XOS, (4) infected + MOS and (5) infected + virginiamycin. The number of S. Enteritidis recovered from the caecum was significantly lower, by 1.6 log, in the MOS, and to a less extent (1.0 log) in the XOS-fed birds compared to the infected control. Coprococcus, Ruminococcus and Enterococcus genera were increased in response to MOS, whereas XOS enriched Clostridium, Lactobacillus and Roseburia MOS, but not XOS, lessened the increase of lipopolysaccharide-induced tumour necrosis factor alpha factor and interferon-γ in caecal tonsils after challenge. The canonical correspondence analysis for cytokine genes showed a correlation with the composition of the microbial community at the genus level. Thus, MOS and XOS differently changed the relative abundance of specific microbial genera and the immune response during infection, and these changes were correlated with their abilities to reduce S. Enteritidis colonisation.
