Abstract

A method for treating a skin disorder, e.g., acne, e.g. acne vulgaris, in a subject is provided. The method comprises administering, e.g., applying, e.g., topically administering, ammonia oxidizing bacteria, e.g., a preparation comprising ammonia oxidizing bacteria, to a surface of the subject. Preparations comprising ammonia oxidizing bacteria for treating such skin disorder, e.g., acne, e.g. acne vulgaris in a subject are also provided.

Claims

1. A method of treating an inflammatory lesion or a non-inflammatory lesion of acne in a subject, comprising:

administering, as a spray, aerosol or mist, a preparation comprising live ammonia oxidizing bacteria, to the skin of the subject, in an amount effective to treat an inflammatory lesion or a non-inflammatory lesion of acne.

2. The method of claim 1, wherein the inflammatory lesion comprises a papule, pustule, or cyst/nodule.

3. The method of claim 1, wherein the non-inflammatory lesion comprises an open comedone or closed comedone.

4. The method of claim 1, wherein administering provides for treatment or improvement of one or more of erythema, edema, scaling, stinging, burning, and itching.

5. The method of claim 1, wherein administering provides for treatment or improvement of one or more of oily appearance, pore appearance, radiance, blotchiness, skin tone evenness, visual smoothness, and tactile smoothness.

6. The method of claim 1, further comprising determining whether the subject is in need of treating acne.

7. The method of claim 1, wherein the preparation of ammonia oxidizing bacteria comprises a buffer solution.

8. The method of claim 7, wherein the buffer solution is an aqueous buffer solution consisting essentially of disodium phosphate and magnesium chloride.

9. The method of claim 1, wherein the ammonia oxidizing bacteria is applied to any one or more of the face, neck, scalp, head, shoulder, arm, leg, underarm, torso, feet, knee, ankle, or buttocks of the subject.

10. The method of claim 1, wherein the preparation of ammonia oxidizing bacteria, further comprises an excipient.

11. The method of claim 1, wherein the ammonia oxidizing bacteria is selected from the group consisting of Nitrosomonas, Nitrosococcus, Nitrosospira, Nitrosocystis, Nitrosolobus, Nitrosovibrio, and combinations thereof.

12. The method of claim 11, wherein the ammonia oxidizing bacteria is Nitrosomonas eutropha (N. eutropha).

13. The method of claim 12, wherein the ammonia oxidizing bacteria is N. eutropha D23, having ATCC accession number PTA-121157.

14. The method of claim 1, wherein the preparation is applied for about 7 to about 28 days.

15. The method of claim 1, wherein an acne treatment selected from the group consisting of:

a topical retinoid, azaelaic acid, salicylic acid, a topical antimicrobial, an oral antibiotic, benzoyl peroxide, an oral anti-androgen, an oral isotretinoin, and combinations thereof is additionally administered to the subject.

16. The method of claim 1, wherein the preparation comprises viable ammonia oxidizing bacteria capable of converting ammonia or ammonium to nitrite at a rate of at least about 50 micromoles nitrite per minute.
