Aerobic vaginitis is a type of vaginitis characterized by an imbalance in the vaginal flora, where there is a decrease in the normal lactobacilli population and an overgrowth of aerobic bacteria. This condition is distinct from bacterial vaginosis, which is typically associated with anaerobic bacteria.

Pathophysiology

Aerobic vaginitis occurs when the normal vaginal microbiota is disrupted, leading to a reduction in protective lactobacilli and an increase in aerobic bacteria such as Escherichia coli, Staphylococcus aureus, and Streptococcus agalactiae. This imbalance can result in inflammation of the vaginal epithelium and symptoms such as irritation, burning, and discharge.

Clinical Presentation

Patients with aerobic vaginitis may present with symptoms including:

• Vaginal irritation and burning
• Yellowish discharge
• Vaginal dryness
• Dyspareunia (pain during intercourse)

The discharge associated with aerobic vaginitis is typically yellow and may have a foul odor, distinguishing it from the grayish discharge of bacterial vaginosis.

Diagnosis

Aerobic vaginitis Gram stain

Diagnosis of aerobic vaginitis is primarily clinical, supported by microscopic examination of vaginal secretions. A Gram stain can reveal the presence of aerobic bacteria and a reduction in lactobacilli. The presence of inflammatory cells and parabasal epithelial cells can also be indicative of the condition.

Treatment

Treatment of aerobic vaginitis involves the use of topical or systemic antibiotics to target the overgrown aerobic bacteria. Commonly used antibiotics include clindamycin and metronidazole. In addition, restoring the normal vaginal flora with probiotics or lactobacilli supplements may be beneficial.

Prevention

Preventive measures for aerobic vaginitis include maintaining good vaginal hygiene, avoiding douching, and using protection during sexual intercourse to prevent infections. Probiotic supplements may also help maintain a healthy balance of vaginal flora.
