Project description:To investigate the impact of gut microbiota deleting and colonizing on hypothalamic health and function, the tissue samples from the germ-free (GF) pigs and the GF pigs colonized gut microbiota (CG) are used to perform whole RNA-seq for gene expression analysis We then performed long RNAs and small RNAs expression profiling analysis using data obtained from the RNA-seq of 3 different hypothalamus samples from the two groups of pigs

Project description:Early-weaning-induced stress causes diarrhea, thereby reduces growth performance of piglets. Gut bacterial dysbiosis emerges as a leading cause of post-weaning diarrhea. The present study was aimed to investigate the effect of capsulized fecal microbiota transportation (FMT) on gut bacterial community, immune response and gut barrier function of weaned piglets. Thirty-two were randomly divided into two groups fed with basal diet for 21 days. Recipient group was inoculated orally with capsulized fecal microbiota of health Tibetan pig daily morning during whole period of trial, while control group was given orally empty capsule. The results showed that the F/G ratio, diarrhea ratio, diarrhea index, and histological damage score of recipient piglets were significantly decreased. FMT treatment also significantly increased the colon length of piglets. Furthermore, the relative abundances of Firmicutes, Euryarchaeota, Tenericutes, Lactobacillus, Methanobrevibacter and Sarcina in colon of recipient piglets were increased, and the relative abundances of Campylobacter, Proteobacteria, and Melainabacteria were significantly decreased compared with control group.

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization on the maturation of the porcine gastric mucosa are largely unknown. The transcriptome of the oxyntic mucosa of 12 caesarian-derived pigs previously associated with microbiota of different complexity was studied. Pigs received sow blood serum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. Then pigs were fed a moist diet . Gastric samples were obtained at on euthanised pigs at 2 weeks of age.

Project description:Improper use of antibiotics in swine could reduce commensal bacteria and possibly increase pathogen infections via the gut resistome. This study aimed to compare the metaproteomic profiles of gut resistome and related metabolism in the cecal microbiota of fattening pigs raised under antibiotic-free (ABF) conditions with those of ordinary industrial pigs (CTRL).

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization on the gut barrier upon the further encounter of favorable bacteria or not, are largely unknown. The jejunal transcriptome of differently perfused intestinal loops of 12 caesarian-derived pigs previously associated with microbiota of different complexity was studied. Pigs received pasteurized sow colostrum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. On days 26-37 of age, jejunal loops were perfused for 8 h with either enterotoxigenic E. coli F4 (ETEC), F4 fimbriae (F4), LAM or saline (CTRL) and jejunal samples were obtained from each piglet immediately afterwards. The analysis of whole mRNA transcript expression was done by Affymetrix©Porcine Gene 1.1 ST array strips, a Robust Multichip Analysis was performed on the CEL files, and Transcripts IDâs were associated to 13,406 Human gene names, based on Sus scrofa Ensemble

Project description:Weaning diet switch brings gut microbiome maturation along with postnatal formation of sufficient matured β-cell mass. The matured gut microbiota elevated agonistic components of bile acid (BA) pool towards farnesoid X receptor (FXR) that was paralleling with the declined β-cell FXR expression. To investigate whether BA/FXR could link postnatal β-cell development and gut microbiota maturation, we forced persistent FXR expression in β cells (βFxrKI) and found decreased neonatal β-cell mass growth and increased glycemia in weaned βFxrKI mice, which could be partially recovered by ablating gut microbiota before weaning. scRNA and scATAC seq analysis showed different β cell growth trajectories with suppressed intrinsic cell proliferation and elevated cell apoptosis in βFxrKI. Caspase-6 was then identified as a dominant β-cell FXR downstream effector to mediate its regulation. The negative regulation of the FXR-Casp6 axis on postnatal β-cell mass expansion reflected a programmed cellular response to gut microbiota maturation in neonatal mice.

Project description:The gut microbiota is closely associated with digestion, metabolism, immunity, and host health. The imbalance of the microbial community in livestock directly affects their well-being and, consequently, productivity. The composition and diversity of the gut microbiota are influenced not only by host genetics but also by environmental factors such as the microbial complexity of the rearing environment, feeds, and antibiotics. Here, we focus on the comparison of gut microbial communities in miniature pigs developed for xenotransplantation in specific pathogen-free (SPF) and conventional (non-SPF) facilities. To identify the disparities in gut microbial composition and functionality between these two environments, 16S RNA metagenome sequencing was conducted using fecal samples. The results revealed that the non-SPF pigs had higher gut microbiota diversity than the SPF pigs. The genera Streptococcus and Ruminococcus were more abundant in SPF pigs than in non-SPF pigs. Blautia, Bacteroides, and Roseburia were exclusively observed in SPF pigs, whereas Prevotella was exclusively found in non-SPF pigs. Carbohydrate and nucleotide metabolism, as well as environmental information processing, were predicted to be enriched in SPF pigs. In addition, energy and lipid metabolism, along with processes related to genetic information, cellular communication, and diseases, were predicted to be enriched in non-SPF pigs. This study makes an important contribution to elucidating the impact of environments harboring a variety of microorganisms, including pathogens, on the gut microbiota of miniature pigs. Furthermore, we sought to provide foundational data on the characteristics of the gut microbiota in genetically modified pigs, which serve as source animals for xenotransplantation.
