a. Off-white (milky or gray), thin, homogeneous discharge with minimal or absent pruritus and inflammation of the vulva and vagina
b. Vaginal secretion pH of greater than 4.5
c. A fishy odor (i.e., a positive whiff test) of the vaginal discharge with the addition of a drop of KOH
d. The presence of clue cells greater than 20 percent of the total epithelial cells on microscopic examination of the saline wet mount
2. Nugent score of 4 to 10 prior to antibiotic treatment
3. Willing to complete a course of metronidazole (vaginal for 5 days)
4. Must have given written informed consent before any study-related activities are carried out and must be able to understand the full nature and purpose of the trial, including possible risks, and adverse effects
5. Regular predictable menstrual cycles or amenorrheic for at least 3 months due to use of a long-acting progestin or continuous use of oral contraceptives

10. Any condition requiring regular periodic use of systemic antibiotics during participation in the study
11. Under treatment for cervical intra-epithelial neoplasia or cervical carcinoma
12. Patients with another vaginal or vulvar condition, which would confound the interpretation of clinical response
13. Taking concomitant diuretics or probiotics or use of vaginal acidifying agents
14. Failure to complete prescribed days of metronidazole with the last dose taken no later than 48 hours prior to allocation to treatment
15. History of allergy to bovine milk, bovine milk products, lactoferrin, or components of the low iron MTbLF Drug Product. Patients with oral lactose intolerance are eligible for the study
