Compositions for fecal floral transplantation and methods for making and using them and devices for delivering them
In alternative embodiments, the invention 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. In alternative embodiments, compositions and 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 travelers diarrhea, or C. difficile or the pseudo-membranous colitis associated with this infection. In alternative embodiments, the invention provides pharmaceuticals and products (articles) of manufacture for delivering these compositions and formulations to an individual, e.g., a human or an animal. The invention also provides devices for delivering a fecal material to a patient.
1. A method comprising:
receiving at a central location a non-frozen stool sample from a donor, wherein the stool sample is within a stool collection device;
testing the stool sample for pathogens;
mixing the stool sample with a cryoprotectant to form a mixture; and
homogenizing the mixture to produce a composition comprising viable bacteria from the stool sample.
2. The method of claim 1 , wherein the method further comprises filtering the composition to produce a filtrate.
3. The method of claim 2 , wherein the method further comprises selectively removing bacteria from the filtrate to produce a composition comprising bacterial species of the phylum Firmicutes.
4. The method of claim 3 , wherein the selectively removed bacteria comprise Bacteroides.
5. The method of claim 3 , wherein the composition comprises a bacterial population consisting essentially of bacterial species of the phylum Firmicutes.
6. The method of claim 2 , wherein the method further comprises lyophilizing the filtrate.
7. The method of claim 6 , wherein the method further comprises encapsulating the lyophilized filtrate into a carrier.
8. The method of claim 7 , wherein the encapsulated filtrate is in a graded release capsule.
9. The method of claim 6 , wherein the method further comprises sending the lyophilized filtrate to a remote location.
10. The method of claim 2 , wherein the stool sample is maintained below room temperature.
11. The method of claim 2 , wherein the filtering separates bacteria from microscopic fiber.
12. The method of claim 2 , wherein the filtering separates bacteria from rough particulate matter.
13. The method of claim 1 , wherein the cryoprotectant comprises trehalose.
14. The method of claim 1 , wherein said mixing further comprises mixing the stool sample with an antioxidant.
15. The method of claim 1 , wherein said mixing further comprises mixing the stool sample with cysteine.
16. The method of claim 1 , wherein an interior of the stool collection device is anaerobic.
17. A method comprising:
receiving at a central location a non-frozen stool sample from a donor, wherein the stool sample is within a stool collection device, and wherein the donor has been prescreened for infectious agents;
mixing the stool sample with a liquid to form mixture, wherein the liquid comprises a cryoprotectant; and
homogenizing the mixture to produce a composition comprising viable bacteria from the stool sample.
18. The method of claim 17 , wherein the method further comprises filtering the composition to produce a filtrate.
19. The method of claim 18 , wherein the method further comprises selectively removing bacteria from the filtrate to produce a composition comprising bacterial species of the phylum Firmicutes.
20. The method of claim 18 , wherein the method further comprises lyophilizing the filtrate.
21. The method of claim 20 , wherein the method further comprises encapsulating the lyophilized filtrate into a carrier.
22. The method of claim 20 , wherein the method further comprises sending the lyophilized filtrate to a remote location.
23. The method of claim 18 , wherein the stool sample is maintained below room temperature.
24. The method of claim 18 , wherein the filtering separates bacteria from microscopic fiber.
25. The method of claim 18 , wherein the filtering separates bacteria from rough particulate matter.
26. The method of claim 17 , wherein an interior of the stool collection device is anaerobic.
