Check List for 16S-based Microbiome Analysis
A reliable database is frequently updated, and most importantly, it is systematically organized by best practices with regards to taxonomic classification of prokaryotic organisms. This

Many genome sequences in public databases are used in metagenomic studies to understand the human microbiome. Unfortunately, many of the taxonomic identities of these genomes
Genes within a genome are never fixed, even for a very short period of time. That’s why we encounter new bacterial variants with novel antibiotic
QIIME is the most widely used open-source bioinformatics pipeline for microbiome analysis (http://qiime.org/). In this document, we provide a guide for using EzBioCloud’s 16S database
Human Microbiome Project funded by US National Institutes of Health (NIH) resulted in the taxonomic profiling data of microbiomes on 19 body sites of 242

Definition of Homology, Orthology and Paralogy Homology is a term used when two genes share a common ancestor. The two genes are considered “homologous” or “not homologous” depending
MOTHUR is a widely used, open-source bioinformatics pipeline for microbiome analysis (https://www.mothur.org/). In this document, we provide a guide for using EzBioCloud’s 16S database with
Nucleotide sequence similarity values are widely used for identification and description of novel species among bacterial taxonomists. There are many different algorithms available for calculating
This document describes the gene set included the current version of UBCG phylogenomics pipeline [Learn more]. Gene COG category COG ID HMM profile Function alaS
Welcome! This tutorial was prepared using a well-known pathogenic species, Vibrio cholerae, (the causal agent of cholera). It is a step-by-step example showing how to
Below you will find the reference to the underline algorithms used through the EzBioCloud and TrueBac ID family of tools and applications. If you cannot
For the purposes of all necessary bioinformatics calculations, a complete 16S rRNA gene sequence is defined as the DNA sequence region between universal PCR primers 27F and
What is the UBCG? UBCG stands for the up-to-date bacterial core gene. It is a method and software tool for inferring phylogenetic relationships using a
In this analysis, the following genomic properties are compared to elucidate possible correlation between them. Genome size in Mbp (million base pairs) DNA GC content in
We will work through with an example file. Please download “Leuconostoc_16s.ezb” here and open it with EzEditor2. This file contains 16S sequences of the type
Bacterial infection may be caused by either new species or novel genetic variants in known bacteria that cannot be identified by conventional methods. 16S rRNA (16S)
A tetra-nucleotide is a fragment of DNA sequence with 4 bases (e.g. AGTC or TTGG). Pride et al. (2003) showed that the frequency of tetra-nucleotides
This article will explain how to carry out phylogenetic analysis using EzEditor2 and other programs. We assume that you already aligned all sequences (either 16S
Alignment of two whole genome sequences can be very useful in comparative genomics and it is particularly helpful when alignments are visualized. By this type
Overall genome relatedness index (OGRI) is a term first coined by Chun & Rainey (2014) and represents any measurements indicating how similar two genome sequences
This document explains how to use EzBioCloud’s “Identity” service using single Sanger sequencing data. Preparations Use ab1 file but not a text file. An ab1
