Normal Vaginal flora

Vaginal wall is lined by stratified squamous epithelium that is several layers thick. These layers contain glycogen, this glycogen is converted into lactic acid which keeps the pH level low and thus protect against the infections.
Lactobacilli accounts for  90% of the total organisms. They are actually useful as the check the growth of other organisms by maintaining the low pH by producing hydrogen peroxide, which inhibits bacteria. Other organisms are Staphylococcus epidermidis, hemolytic streptococci and coliforms.
