Probiotic and prebiotic compositions, and methods of use thereof for modulation of the microbiome
Probiotic compositions containing non-pathogenic microbial entities, e.g., bacterial entities, are described herein. The probiotic compositions may optionally contain or be used in conjunction with one or more prebiotics. Uses of the probiotic compositions to treat or prevent disorders of the local or systemic microbiome in a subject are also provided.
1. A method of treating irritable bowel syndrome (IBS) in a human subject in need thereof, comprising administering to the subject a pharmaceutical composition comprising Blautia hydrogenotrophica.
2. The method of claim 1 , wherein the pharmaceutical composition further comprises a pharmaceutically acceptable excipient.
3. The method of claim 1 , wherein the irritable bowel syndrome (IBS) is characterized by one or more of abdominal discomfort or pain, abnormal stool passage, passage of mucus, bloating, or feeling of abdominal distension.
4. The method of claim 1 , wherein the irritable bowel syndrome (IBS) is diarrhea-predominant IBS.
5. The method of claim 1 , wherein the irritable bowel syndrome (IBS) is constipation-predominant IBS.
6. The method of claim 1 , wherein the irritable bowel syndrome (IBS) is constipation alternating with diarrhea (alternating IBS).
7. The method of claim 1 , wherein the subject has a dysbiosis.
8. The method of claim 7 , wherein the dysbiosis is a gastrointestinal dysbiosis.
9. The method of claim 1 , wherein the level of Blautia hydrogenotrophica is augmented in the gastrointestinal tract of the subject.
10. The method of claim 9 , wherein the Blautia hydrogenotrophica engraft in the gastrointestinal tract of the subject.
11. The method of claim 1 , wherein the level of a bacterial species not present in the pharmaceutical composition is augmented in the gastrointestinal tract of the subject.
12. The method of claim 1 , further comprising administering a prebiotic to the subject.
13. The method of claim 12 , wherein the prebiotic augments the growth of the bacterial population present in the pharmaceutical composition.
14. The method of claim 12 , wherein the prebiotic comprises a monomer or polymer selected from the group consisting of arabinoxylan, xylose, soluble fiber dextran, soluble corn fiber, polydextrose, lactose, N-acetyl-lactosamine, glucose, and combinations thereof.
15. The method of claim 12 , wherein the prebiotic comprises a monomer or polymer selected from the group consisting of galactose, fructose, rhamnose, mannose, uronic acids, 3′-fucosyllactose, 3′sialylactose, 6′-sialyllactose, lacto-N-neotetraose, 2′-2′-fucosyllactose, and combinations thereof.
16. The method of claim 12 , wherein the prebiotic comprises a monosaccharide selected from the group consisting of arabinose, fructose, fucose, lactose, galactose, glucose, mannose, D-xylose, xylitol, ribose, and combinations thereof.
17. The method of claim 12 , wherein the prebiotic comprises a disaccharide selected from the group consisting of xylobiose, sucrose, maltose, lactose, lactulose, trehalose, cellobiose, and combinations thereof.
18. The method of claim 12 , wherein the prebiotic comprises a polysaccharide, wherein the polysaccharide is xylooligosaccharide.
19. The method of claim 1 , wherein the pharmaceutical composition comprises only one bacterial species.
20. The method of claim 1 , wherein the method reduces inflammation in the subject.
