Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purposes of this study is to identify types of bacteria that reside in the intestine of healthy individuals and compare them to individuals with Multiple Sclerosis (MS). There has been a lot of research in other autoimmune diseases which has demonstrated the importance of stomach "gut" bacteria because it has an important relationship with the immune system, but this has never been studied in MS patients. In this study investigators aim to show differences in the gut bacteria between healthy individuals and those with MS, to provide a basis for future research studying how diet can affect MS through its effects on the "gut" bacteria.

Additionally, this study will be looking at the effects of dimethyl fumarate on cerebrospinal fluid, plasma and MRI in MS patients taking dimethyl fumarate as compared to those with MS not on dimethyl fumarate or other disease modifying therapy and those who do not have MS (normal controls).

3. Expanded Disability Status Scale (EDSS) score between 0 and 7, inclusive, at screen.

Exclusion (MS Population Only)

General and Medical History Exclusions

2. Current smoker
3. Any contraindication to having a brain MRI (e.g. pacemaker, MRI-incompatible aneurysm clips, artificial heart valves, or other metal foreign body; claustrophobia that cannot be medically managed) or contraindication for administration of gadolinium-contrast agents.
4. Clinically significant brain MRI findings other than those related to MS, as judged by the investigator, at screen.
5. Any contraindications to having a Lumbar puncture (LP) (i.e. Aspirin (ASA) greater than 325mg/day, Coumadin, Plavix, decreased platelet count) as determined by the investigator.
6. History of Chronic Urinary Tract Infections, Irritable Bowel Syndrome, Inflammatory Bowel Disease, Diabetes Mellitus or vascular disease as determined by history and investigator decision
7. Evidence or history of autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus, ulcerative colitis, diabetes mellitus or others) with the exception of MS.
8. History of or current clinically relevant gastrointestinal bleeding or other gastrointestinal diseases or processes that may interfere with the analysis of stool samples per protocol.
9. Any sign of chronic active infection (e.g. urinary tract infection (UTI), bronchitis, hepatitis and tuberculosis) except for those requiring topical medication for treatment (e.g., athletes foot), or screening laboratory evidence consistent with a significant chronic active acute infection requiring systemic treatment.
