Welcome to Emory Microbiome Group page. This site aims to provide some basic information about resources available for microbiome projects at Emory, as well as information about seminars, courses and faculty interested in this area. The microbiome group also runs an informal research in progress seminar. 

What is the Microbiome?

The microbiome is the community of bacteria, viruses, fungi and protests associated with a particular ecological niche, such as soil or the human gut.  The microbiome is generally studied using high-throughput sequencing technologies, either through PCR amplification of conserved regions (commonly the bacterial 16S gene)  or random shotgun approaches.  

There is enormous interest in associating the composition of the microbiome with many aspects of human health (including diabetes, obesity, infectious disease, antibiotic overuse, cancer, to name a few).

Checklist for a New Microbiome Sequencing Project

Projects usually fall into three phases: 1. Planning, 2. Sampling & Sequencing and 3. Data analysis.  

Each phase may include the following steps:

1. Planning

• Decide whether the project theme is discovery based or hypothesis driven
• Decide what sample metadata to collect (e.g clinical information ,location) and how it will be stored.
• Begin to obtain research compliances and approvals for human and animal use, biosafety, etc. (Visit this handy Hitchhiker's Guide.)
• Decide whether to use an amplicon based sequencing (e.g. 16S) or shotgun metagenomics approach
• How much sequence data per sample (this will depend on the sample type, sequence technology, aims of experiment, budget)
• Consider which sequencing technology is most appropriate and which software will likely be used for analysis
• Plan logistics of sample extraction and storage.
• Perform power calculations to estimate the number of samples necessary to achieve stated objectives
• Develop budget. Costs can  include  sampling & DNA extraction supplies, sequencing, sample and DNA storage, data storage and processing, labor for taking samples, DNA extraction and sequencing, data analysis

2. Sampling & Sequencing

• Collect samples
• Store before DNA extraction, if necessary
• DNA extraction
• Sequencing
• Long term storage of DNA and/or samples post-sequencing

3. Data analysis

• Sequence quality assessment
• Human sequence removal (if necessary)
• Data analysis pipeline (operational taxonomic unit assignment, metabolic reconstruction etc) OTU definition
• Exploratory data analysis
• Inferential analysis
• Hypothesis testing
• Public database submission
• Long term data storage
• Manuscript writing
