Abstract

An anaerobic chamber system to evaluate human enteric disease is described herein that can be used to test therapeutic components. In specific embodiments, the anaerobic chamber is used to determine the effect of one or more bacterial communities on ex vivo enteroid cultures. In one application, the anaerobic chamber system is used to determine the efficacy of therapeutic components in ameliorating human enteric disease using personalized medicine.

First claim

What is claimed is:

1. A co-culture system for co-culturing anaerobic microbes and gut tissue, comprising two or more anaerobic chambers and two or more aerobic chambers, and a gas adjustable chamber comprising a gas;
wherein each anerobic chamber is removably insertable into a single aerobic chamber;
wherein each anaerobic chamber comprises a gas permeable base, wherein when a single anaerobic chamber is inserted into the single aerobic chamber, the single anaerobic chamber is gaseously communicable with the single aerobic chamber;
wherein the gas permeable base comprises gut tissue of a subject in the anaerobic chamber;
wherein the gut tissues comprises an apical side and a basolateral side; wherein the apical side faces the anaerobic chamber; wherein the apical side is anaerobic and the basolateral side is oxygenated;
and wherein there is a gas permeable side common to the two or more aerobic chambers and the gas adjustable chamber.

2. The system of claim 1 , wherein the system is housed in an anaerobic atmosphere.

3. The system of claim 1 , wherein the gas adjustable chamber comprises a mechanism for circulation.

4. The system of claim 1 , wherein the gas adjustable chamber is configured to receive the gas via a conduit.

5. The system of claim 4 , wherein a source of the gas is a tank.

6. The system of claim 1 , wherein the gas is blood gas.

7. The system of claim 6 , wherein the blood gas is comprised of oxygen, carbon dioxide, and nitrogen.

8. The system of claim 1 , wherein the anaerobic chamber is adapted to be mounted on one or more gaskets.

9. The system of claim 1 , wherein the aerobic chamber comprises one or more multi-well plates.

10. The system of claim 1 , wherein at least part of the aerobic chamber comprises glass.

11. The system of claim 2 , the gas permeable side comprises one or more openings.

12. The system of claim 1 , wherein a two-sided adhesive is mounted onto the gas permeable side in the anaerobic chamber.

13. The system of claim 1 , wherein the anaerobic chamber is adapted to be mounted onto the aerobic chamber.

14. The system of claim 1 , wherein an adapter is mounted onto the aerobic chamber.

15. The system of claim 1 , wherein the system comprises a lid.

16. The system of claim 14 , wherein the adapter is secured onto the aerobic chamber and the gas adjustable chamber.

17. The system of claim 1 , wherein the gut tissue comprises one or more enteroids.

18. The system of claim 1 , wherein the gut tissue is plated as a monolayer and differentiated within the anaerobic chamber.

19. The system of claim 1 , wherein the anaerobic chamber comprises one or more microbes.

20. The system of claim 19 , wherein the one or more microbes are bacteria.

21. The system of claim 20 , wherein the one or more bacteria are bacteriodetes, firmicutes, actinobacteria, proteobacteria, verrucomicrobia, or a combination thereof.

22. The system of claim 19 , wherein the one or more microbes are viruses.

23. The system of claim 22 , wherein the one or more viruses are Rotaviruse, “Norwalk-like” viruse, Adenoviruse, Astroviruse, “Sappro-like” viruse, Toroviruse, Coronaviruse, Picornavirue, and Herpesvirus, or a combination thereof.

24. The system of any one of claim 19 , wherein the one or more microbes are fungi.

25. The system of claim 24 , wherein the one or more fungi are Ascomycota, Basidiomycota, Mucoromycota, Saccharomyces, Malassezia, Candida, Cyberlindnera, Penicillium, Cladosporium, Aspergillus, Agaricus, Fusarium, Pichia, Debaryomyces, Galactomyces, Altemaria , and Clavispora , or a combination thereof.

26. The system of claim 1 , wherein the anaerobic chamber comprises media for the enteroid cultures.

27. The system of claim 26 , wherein the media for the enteroid cultures comprises one or more growth factors in the anaerobic chamber.
