Abstract

The subject invention provides materials methods for reducing infections in subjects. The materials methods utilize chlorhexidine, which has been found to be surprisingly non-toxic. The lack of toxicity facilitates the use of chlorhexidine in contexts that were not previously thought to be possible.

Claims (21)

1. A method for reducing infection at a site in a subject, wherein said method comprises administering to the site an aqueous solution that comprises chlorhexidine at a concentration of about 0.05% or less, wherein the site is in a urogenital tract.

2. The method of claim 1 , wherein the chlorhexidine is chlorhexidine gluconate.

3. The method of claim 1 , further comprising applying suction to the site.

4. The method of claim 1 , wherein the infection comprises biofilm.

5. A method for reducing infection at a site in a subject, wherein said method comprises administering to the site an aqueous solution that comprises chlorhexidine at a concentration of 1% or less, wherein the site is a urogenital tract, and wherein the method further comprises applying suction to the site.

6. The method of claim 5 , wherein the chlorhexidine is chlorhexidine gluconate.

7. The method of claim 5 , wherein the infection comprises biofilm.

8. The method of claim 5 , wherein the aqueous solution consists of an aqueous solution of chlorhexidine and, optionally, a buffer.

9. The method of claim 5 , wherein the concentration of chlorhexidine is about 0.05% or less.

10. The method of claim 9 , wherein the concentration of chlorhexidine is about 0.05%.

11. A method for reducing infection at a site in a subject, wherein said method comprises administering to the site an aqueous solution that comprises chlorhexidine at a concentration of 1% or less, wherein the site is a urogenital tract, and wherein the infection comprises biofilm.

12. The method of claim 11 , wherein the chlorhexidine is chlorhexidine gluconate.

13. The method of claim 11 , further comprising applying suction to the site.

14. The method of claim 11 , wherein the aqueous solution consists of an aqueous solution of chlorhexidine and, optionally, a buffer.

15. The method of claim 11 , wherein the concentration of chlorhexidine is about 0.05% or less.

16. The method of claim 15 , wherein the concentration of chlorhexidine is about 0.05%.

17. A method for reducing infection at a site in a subject, wherein said method comprises administering to the site an aqueous solution that comprises chlorhexidine at a concentration of 0.05% or less, wherein the site is a urogenital tract, and wherein the aqueous solution consists of an aqueous solution of chlorhexidine and, optionally, a buffer.

18. The method of claim 17 , wherein the chlorhexidine is chlorhexidine gluconate.

19. The method of claim 17 , further comprising applying suction to the site.

20. The method of claim 17 , wherein the infection comprises biofilm.

21. The method of claim 17 , wherein the concentration of chlorhexidine is about 0.05%.
