Method and composition for prevention and treatment of female lower genital tract microbial infections
First Claim
1. A method for treating or reducing susceptibility to a microbial infection in the lower genital tract of a female mammal comprising infusing into the lower genital tract of the mammal an effective amount of an aqueous composition comprising greater than about 125 ppm to about 1000 ppm chlorine dioxide and a pharmaceutically acceptable carrier, wherein the molar ratio of chlorine dioxide to chlorite in the composition is at least 5:
- 1 and the pH is compatible with the tract.

Abstract
Methods for preventing and treating microbial infections in the mammalian female lower genital tract such as vulvitis, vaginitis, cervicitis, and endometritis involve the intra-vaginal and/or intra-uterine infusion of a solution containing a pharmacologically acceptable carrier and chlorine dioxide in an amount ranging from about 5 ppm to 1000 ppm, and having a chlorine dioxide to chlorite ratio of at least 5:1. Typical solutions exhibit a pH compatible with the lower genital tract, e.g., a pH from about 5 to about 7.5. In many embodiments, chlorine dioxide in the solution is produced by reacting a chlorite with a mineral acid and adjusting the pH, by reacting a chlorite with an organic acid having a pK of about 2.8 to 4.2, or by reacting a chlorite at a pH below about 5.5 with a heat-activated saccharide in the presence of an organic acid having a pK of about 2.8 to about 4.2. Sodium chlorite is employed in preferred embodiments.

19. A method for treating or reducing susceptibility to post-parturient microbial infections in the lower genital tract of mares or cows comprising infusing into the tract of the cow or mare after birth 1 to 5 liters of a solution that contains a chlorite selected from the group consisting of an alkali metal chlorite, an alkaline earth metal chlorite, and mixtures thereof, reacted with an acid in amounts sufficient to yield greater than about 125 ppm to about 1000 ppm chlorine dioxide, provided that the ratio of chlorine dioxide to chlorite in the solution is at least 5:
- 1, and the pH of the composition is compatible with the tract.
