Analyzed gut microbiota using QIIME, Phyloseq, metagenomSeq, randomForest, and LEfSe. a) LDA scores of the most discriminant fungal taxa identified by LEfSe. We found that the cancerous pancreas harbors a markedly more abundant microbiome compared with normal pancreas in both mice and humans, and select bacteria are differentially increased in the tumorous pancreas compared with gut. Microbiome data analysis seems daunting, but it is not. QIIME is an open-source bioinformatics pipeline for performing microbiome analysis from raw DNA sequencing data. In addition to neurological symptoms, ASD subjects frequently suffer from gastrointestinal abnormalities, thus implying a role of the gut microbiota in ASD gastrointestinal pathophysiology. This is useful for several reasons: converting biom format tables to tab-delimited tables for easy viewing in programs such as Excel. LEfSe is a biomarker discovery tool used to identify features (taxa, in this case) from high-dimensional genomic data that characterize differences between two or more biological conditions. While many studies have focused on areas like Bangladesh and West Bengal, India, disadvantaged regions within Nepal have also suffered from arsenic contamination levels, with wells and other water sources possessing arsenic contamination over the recommended WHO and EPA limit of 10 μg/L, some wells.
