To investigate the dynamic relationship between the intestinal microbiota and Inflammation in
 subjects with Parkinson's disease. The current study examines the differential microbiome of
 the gut in subjects with parkinsonism. The current study determines whether certain
 Parkinson's subtypes are prone to pro-inflammatory microbiomes. This study also explores
 whether the intestinal microbiome in post-appendectomy Parkinson's subjects is modified as
 appendix has a role in regulating intestinal microbiome. The current study will examine
 whether microbiome changes influence inflammatory markers in the blood.
Inclusion Criteria:

 -  Individuals with Parkinson's disease (including multiple system atrophy). Males and
 females are eligible for the study. Appendectomized cohort must have had their
 appendectomy at least 20 years before Parkinson's disease onset

 Exclusion Criteria:

 -  1. Body Mass Index greater than or equal to 35 or less than or equal to 18. 2. Vital
 signs outside of acceptable range at Screening Visit, i.e., blood pressure >160/100,
 oral temperature >100°F, pulse >100.

 3. Use of any of the following drugs within the last 6 months:

 -  systemic antibiotics, antifungals, antivirals or antiparasitics (intravenous,
 intramuscular, or oral);

 -  cytokines;

 -  methotrexate or immunosuppressive cytotoxic agents;

 -  large doses of commercial probiotics consumed (greater than or equal to 108 cfu
 or organisms per day) - includes tablets, capsules, lozenges, chewing gum or
 powders in which probiotic is a primary component. Ordinary dietary components
 such as fermented beverages/milks, yogurts, foods do not apply.

 4. Acute viral/bacterial infection disease at the time of sampling (defer
 sampling until subject recovers). Acute disease is defined as the presence of a
 moderate or severe illness with or without fever.

 5. Unstable dietary history as defined by major changes in diet during the
 previous month, where the subject has eliminated or significantly increased a
 major food group in the diet.

 6. Recent history of chronic alcohol consumption defined as more than five 1.5-
 ounce servings of 80 proof distilled spirits, five 12-ounce servings of beer or
 five 5-ounce servings of wine per day.

 7. Positive test for HIV, HBV or HCV. 8. Any confirmed or suspected
 condition/state of immunosuppression or immunodeficiency (primary or acquired)
 including HIV infection.

 9. Major surgery of the GI tract, with the exception of cholecystectomy and
 appendectomy, in the past five years. Any major bowel resection at any time.

 10. History of active uncontrolled gastrointestinal disorders or diseases
 including:

 -  inflammatory bowel disease (IBD) including ulcerative colitis
 (mild-moderate-severe), Crohn's disease (mild-moderate-severe), or indeterminate
 colitis;

 -  irritable bowel syndrome (IBS) (moderate-severe);

 -  persistent, infectious gastroenteritis, colitis or gastritis, persistent or
 chronic diarrhea of unknown etiology, Clostridium difficile infection (recurrent)
 or Helicobacter pylori infection (untreated); 11. Female who is pregnant or
 lactating. 12. Atypical or secondary Parkinson's disease 13. Adults that are
 unable to consent, individuals that are not yet adults and prisoners are not
 eligible for this study
