The human microbiome is the community of microbes associated with the human body. Disruption and imbalances in these microbiomes can cause diverse symptoms from depression to eczema. Celiac Disease (CD) is characterized by an immune response in the small intestine that is triggered by the protein gluten, found in wheat. Previous studies have identified microbial dysbiosis in patients with CD. To better understand how these dysbiosis can affect the disease itself we will exam the microbiome diversity and composition in CD patients and healthy individuals on gluten-free diets. This will help identify what microbiome changes are associated with CD compared to those that are caused by the CD patients lack of gluten in their diet. The microbial populations of three different groups will be analyzed: 1. those diagnosed with CD and on a gluten-free diet, 2. those who do not have CD and are on a gluten-free diet, and 3. those who do not have CD and are not on a specific diet. The dietary and disease influences on the microbiome of the gastrointestinal tract will be analyzed via a single stool sample collected from each study subject. Microbial DNA was extracted using the QIAamp PowerFecal DNA kit following manufacturer's specifications (Qiagen) V3/V4 region of 16s rRNA will be sequenced using the 600 cycle v3 MiSeq kit (Illumina) The results of the analysis will be compared to existing microbial genome databases to determine the composition of microbes present in the study groups.
