Association of gut microbiota and gut metabolites and adverse outcomes in biliary atresia: A longitudinal prospective study.

Background: The Kasai portoenterostomy (KPE) aims to re-establish bile flow in biliary atresia (BA); however, BA remains the commonest indication for liver transplantation in pediatrics. Gut microbiota-host interplay is increasingly associated with outcomes in chronic liver disease. This study characterized fecal microbiota and fatty acid metabolites in BA.

Faecal microbiota and cytokine profiles of rural Cambodian infants linked to diet and diarrhoeal episodes.

The gut microbiota of infants in low- to middle-income countries is underrepresented in microbiome research. This study explored the faecal microbiota composition and faecal cytokine profiles in a cohort of infants in a rural province of Cambodia and investigated the impact of sample storage conditions and infant environment on microbiota composition. Faecal samples collected at three time points from 32 infants were analysed for microbiota composition using 16S rRNA amplicon sequencing and concentrations of faecal cytokines.

An update on the current understanding of the infant skin microbiome and research challenges.

Multiple factors contribute to establishment of skin microbial communities in early life, with perturbations in these ecosystems impacting health. This review provides an update on methods used to profile the skin microbiome and how this is helping enhance our understanding of infant skin microbial communities, including factors that influence composition and disease risk. We also provide insights into new interventional studies and treatments in this area.

An efficient method for high molecular weight bacterial DNA extraction suitable for shotgun metagenomics from skin swabs.

The human skin microbiome represents a variety of complex microbial ecosystems that play a key role in host health. Molecular methods to study these communities have been developed but have been largely limited to low-throughput quantification and short amplicon-based sequencing, providing limited functional information about the communities present. Shotgun metagenomic sequencing has emerged as a preferred method for microbiome studies as it provides more comprehensive information about the species/strains present in a niche and the genes they encode.
