Project description:G. lamblia is a fecal-oral transmitted human enteropathogenic protozoan with extremely high incidence in endemic areas in Africa and Asia particularly in the infant population. It homes to the proximal small intestine and induced diarrhea and malabsoption. Here we established a novel murine G. lamblia infection model and analyzed the tissue response and downstream microbial and metabolic effects in the host.

Project description:Diarrhea remains a major cause of death in children. Current diagnostic methods largely rely on stool culture and suffer from low sensitivity and inadequate specificity, often leading to inappropriate treatment. The objective of the present study was to use RNA sequencing (RNAseq) analysis to determine blood transcriptional profiles specific for several common pathogenic bacteria and viruses that cause diarrhea in children. We collected whole blood samples from children in Mexico having diarrhea associated with a single pathogen and without systemic complications. Our RNAseq data suggested that the blood signatures can differentiate children with diarrhea from healthy children either with or without bacterial colonization. Moreover, we detected different expression profiles from bacterial and viral infection, demonstrating for the first time the use of RNAseq to identify the etiology of infectious diarrhea. Whole blood from 207 children including children with diarrhea caused by rotavirus (n=55), E.coli (n=55), Salmonella (n=36), Shigella (n=37) and control children (n=24).

Project description:<p><strong>BACKGROUND:</strong> Diarrhea is common in infants, particularly, children less than 2 years old. Intractable or protracted infancy diarrhea is typically associated with feeding intolerance and malabsorption that is lethal for newborns. This study aimed to evaluate the effectiveness of baizhu shaoyao decoction in reducing functional diarrhea induced by weaning stress, while also delving into its potential mechanisms of action.</p><p><strong>RESULTS:</strong> Piglets were allocated into 5 groups, with each group receiving designated medication for a continuous 14-day period: control, zaohu powder, as well as low-, medium- and high-dose baizhu shaoyao decoction groups (n = 6 piglets per group). To identify diarrhea-related biomarkers, microbial communities, functions and metabolites were compared between the early-weaned piglets (control group) and those treated with 1.28 g/kg baizhu shaoyao decoction (medium-dose baizhu shaoyao decoction group). Our findings revealed significant shifts in microbial composition, function and metabolic profiles in piglets from the medium-dose baizhu shaoyao decoction group, intricately associated with the host's diarrhea status. Furthermore, carbohydrate metabolism and biosynthesis, lipid and amino acid metabolism, glycan activity and carbohydrate digestive enzymes exhibited downregulation in piglets of the medium-dose baizhu shaoyao decoction group compared to those in the control group. Transcriptome analysis highlighted the pivotal role of the FoxO1/3 transcription factor in mitigating weaning stress, particularly through the augmentation of CD4+/CD8+ T cell proportions. Our findings underscored that baizhu shaoyao decoction's therapeutic effects on weaning stress involve intestinal barrier restoration, modulation of brain-gut peptide expression and a reduction in mast-cell activity in the ileum.</p><p><strong>CONCLUSIONS:</strong> The key metabolites (chenodeoxycholyglycine, chenodeoxycholyltaurine, dinoprost, chenodeoxyglycocholic acid, glycochenodeoxycholic acid, glycocholic acid, N-choloylglycine, 5-trans-PGE2, Pregnanediol 3-O-glucuronide, spermidine and spermine) exhibited strong correlations with the abundance of <em>Clostridia_bacterium</em> and <em>Lachnospiraceae_bacterium</em>, emphasizing the significance of <em>Clostridia_bacterium</em> and <em>Lachnospiraceae_bacterium</em> in gut metabolism and function. Besides, this study suggests the potential efficacy of baizhu shaoyao decoction in addressing early post-weaning stress-induced diarrhea in infants, showcasing promising prospects for translational and clinical applications.</p>

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..
