Compositions for fecal floral transplantation and methods for making and using them and devices for delivering them
The present disclosure provides compositions, e.g., formulations, used for gastric, gastrointestinal and/or colonic treatments or lavage, e.g., orthostatic lavage, e.g., for inducing the purgation (e.g., cleansing) of a gastrointestinal (GI) tract, including a colon; and methods for making and using them. Methods of the invention are used for the stabilization, amelioration, treatment and/or prevention of constipation, for the treatment of abdominal pain, particularly non-specific abdominal pain, and diarrhea, including diarrhea caused by a drug side effect, a psychological condition, a disease or a condition such as Crohn's Disease, a poison, a toxin or an infection, e.g., a toxin-mediated traveler's diarrhea, or C. difficile or the pseudo-membranous colitis associated with this infection.
1. A method, comprising:
obtaining a stool from a human donor, wherein the stool comprises a collection of fecal bacteria;
expanding the collection of fecal bacteria in a first culture medium without any pre-segregating out of any particular bacterial species;
expanding the collection of fecal bacteria in a second culture medium without any pre-segregating out of any particular bacterial species; and
combining the expanded fecal bacteria from the first and second culture media to produce a microbial composition.
2. The method of claim 1 , wherein the first and second culture media have different media compositions.
3. The method of claim 1 , wherein at least one of expanding the collection of fecal bacteria in a first culture medium and expanding the collection of fecal bacteria in a second culture medium occurs under anaerobic conditions.
4. The method of claim 1 , further comprising supplementing the first culture medium, the second culture medium or the microbial composition with a bacterial isolate.
5. The method of claim 1 , wherein the microbial composition comprises bacteria selected from the group consisting of Firmicutes, Bacteroides , and a combination thereof.
6. The method of claim 1 , wherein the collection of fecal bacteria is separated from rough particulate matter of the stool prior to expanding.
7. The method of claim 1 , further comprising formulating the microbial composition as a pharmaceutical composition.
8. The method of claim 7 , wherein the formulating comprises lyophilizing the microbial composition.
9. The method of claim 7 , wherein the formulating comprises encapsulating the microbial composition.
10. The method of claim 7 , wherein the pharmaceutical composition comprises a cryoprotectant.
11. A method of manufacturing a pharmaceutical composition, comprising:
culturing a fecal flora from a stool of a healthy human donor without any pre-segregating out of any particular bacterial species; and
formulating the pharmaceutical composition to include multiple bacterial species from the cultured fecal flora.
12. The method of claim 11 , wherein the culturing occurs under anaerobic conditions.
13. The method of claim 11 , further comprising mixing the bacteria from the cultured fecal flora with a bacterial isolate.
14. The method of claim 11 , wherein the cultured fecal flora comprises bacteria selected from the group consisting of Firmicutes, Bacteroides , and a combination thereof.
15. The method of claim 11 , wherein the formulating comprises lyophilizing the bacteria from the cultured fecal flora.
16. The method of claim 11 , wherein the formulating comprises encapsulating the bacteria from the cultured fecal flora.
17. The method of claim 11 , wherein the fecal flora is separated from rough particulate matter of the stool prior to culturing.
18. The method of claim 11 , wherein the pharmaceutical composition comprises a cryoprotectant.
19. The method of claim 11 , wherein the pharmaceutical composition comprises an antioxidant.
20. The method of claim 11 , wherein the method comprises culturing multiple fecal flora from stool of multiple healthy human donors, and formulating the pharmaceutical composition to include multiple bacterial species from the multiple cultured fecal flora.
