Capsulized fecal microbiota transportation ameliorates post-weaning diarrhea through modulating the gut microbiota in piglets

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.

The difference between diarrhea piglets and normal piglets

Project description:Sixty crossbred piglets (Duroc*Landrace*Yorkshire) weaned at the age of 21 days were maintained for one week and had free access to feed and water. During this week, all the piglets were scored for the severity of diarrhea. Diarrhea index was scored as follows: 1= hard feces; 2= no scours, feces of normal consistency; 3= mild scours, soft, partially formed feces; 4= moderate scours, loose, semi-liquid feces; 5= watery feces; as previously did Those piglets with a score of 4 or 5 for three continuous days were designated as diarrhea piglets, while those piglets with a score of 1 or 2 for three continuous days were designated as normal piglets..

Intestinal accumulation of microbiota-produced succinate caused by loss of microRNAs leads to diarrhea in weanling piglets

Project description:Diarrheal disease is a common health problem with complex causality. Although diarrhea is accompanied by disturbances in microbial diversity, how gut microbes are involved in the occurrence of diarrhea remains largely unknown. Here, using a pig model of post-weaning stress-induced diarrhea, we aim to elucidate and enrich the mechanistic basis of diarrhea. We found significant alterations in fecal microbiome, their metabolites, and microRNAs levels in piglets with diarrhea. Specifically, loss of ssc-miRNA-425-5p and ssc-miRNA-423-3p, which inhibit the gene expression of fumarate reductase (<i>frd</i>) in <i>Prevotella</i> genus, caused succinate accumulation in piglets, which resulted in diarrhea. Single-cell RNA sequencing indicated impaired epithelial function and increased immune response in the colon of piglet with diarrhea. Notably, the accumulated succinate increased colonic fluid secretion by regulating transepithelial Cl-secretion in the epithelial cells. Meanwhile, succinate promoted colonic inflammatory responses by activating MyD88-dependent TLR4 signaling in the macrophages. Overall, our findings expand the mechanistic basis of diarrhea and suggest that colonic accumulation of microbiota-produced succinate caused by loss of miRNAs leads to diarrhea in weanling piglets.

Serum miRNA expression profiles in suckling piglets and weaning piglets

Project description:MicroRNAs (miRNAs) in serum are very stable and specific. Moreover, serum miRNAs are non-destructive and convenient. Studies have shown that the changes of serum miRNAs are closely relative to the pathological stresses and diseases. Our previous studies suggested that weaning stress induced the abnormal miRNA transcriptome in the intestine of piglets. In this project, we will further screen serum miRNA expression in piglets induced by weaning stress using miRNA microarray. Microarrays containing 422 porcine unique miRNA probes were employed to identify differences in the expression patterns of the miRNA between weaning piglets at 4 d after weaning and suckling piglets at the same days old. A total of 115 differentally expressed miRNAs were found,therein 63 miRNAs upregulated and 52 miRNA downregulated; 64 miRNAs are statistically significant but have low signals (signal < 500);122 miRNAs are not statistically significant (p > 0.01); the remaining 132 miRNAs have not detected signals.

The Effects of Bacillus licheniformis-fermented Products on Chronic Feline Diarrhea and Intestinal Microbiota

Project description:Bacillus licheniformis-fermented products (BLFP) are probiotics with antibacterial, antiviral, and anti-inflammatory properties that can improve growth performance. This study aimed to, firstly, compare the fecal microbiota of cats with chronic diarrhea (n = 8) with that of healthy cats (n = 4) from the same household using next-generation sequencing and, secondly, evaluate the effectiveness of oral administration of BLFP in relieving clinical signs and altering the intestinal microbiota in diarrheal cats. Six out of eight cats with diarrhea showed clinical improvement after BLFP administration for 7 days, and in two cats the stool condition was normal. A higher Firmicutes/Bacteroidetes ratio was noted in the feces of diarrheal cats without clinical improvement as compared with those in the healthy control group and in the diarrheal cats with clinical improvement after receiving BLFP. The phylum Bacteroidetes and class Bacteroidia decreased significantly in diarrheal cats regardless of BLFP administration. Blautia spp., Ruminococcus torques, and Ruminococcus gnavus, which belong to the Clostridium cluster XIVa and have been reported as beneficial to intestinal health, increased significantly in feces after BLFP treatment. Furthermore, a significant decrease in Clostridium perfringens was noted in diarrheal cats after BLFP administration. Overall, BLFP could be a potential probiotic to relieve gastrointestinal symptoms and improve fecal microbiota in cats with chronic diarrhea.

16S rRNA sequencing of cecal microbiota from neonatal mice pre- and post-weaning

Project description:Neonatal mice were susceptible to cryptosporidium infection at 1- and 2-weeks of age, but were resistant to infection at 3- and 6-weeks of age. Diet and microbial changes are known to occur during the weaning transition in mice and we hypothesized that these changes in the intestinal luminal environment might influence resistance and susceptibility to cryptosporidium infection. As one part of testing this hypothesis, cecal microbiota composition was determined by 16S ribosomal RNA sequencing of DNA isolated from the cecal contents of mice at 1 week, 2 weeks, 3 weeks, and 6 weeks of age.
