When the normal balance of vaginal flora is disturbed, an overgrowth of organisms can occur, leading to common endogenous infections like candidiasis and bacterial vaginosis. Candidiasis is caused by an overgrowth of the fungus Candida, while bacterial vaginosis results from an imbalance of normal vaginal flora. Both infections can cause symptoms like abnormal discharge and irritation. Prompt treatment with antimicrobials can resolve the infections.
