Definition and classification of abnormal vaginal flora

Area of Science:

• Gynecology
• Microbiology
• Clinical Diagnostics

Background:

• Vaginal microflora plays a crucial role in women's health, with infections posing significant health concerns.
• Accurate diagnosis of vaginal flora constituents is essential for effective treatment of infections.

Purpose of the Study:

• To review diagnostic tools for studying vaginal flora, including their advantages and disadvantages.
• To discuss different types of bacterial flora and diagnostic challenges in pathological conditions.
• To introduce 'aerobic vaginitis' as a distinct clinical entity.

Main Methods:

• Comparison of diagnostic techniques: Gram-stained vaginal preparations, Pap smears, cultures, nucleic acid detection, and office-based microscopy.
• Focus on the utility of phase-contrast microscopy (x400 magnification) for fresh vaginal smears.
• Analysis of diagnostic accuracy and limitations of each method.

Main Results:

• Office-based microscopy of fresh vaginal smears is highly effective for diagnosing a wide range of vaginal flora conditions.
• Specific challenges exist in diagnosing pathological conditions and differentiating flora types.
• The 'intermediate flora' and 'aerobic vaginitis' are highlighted as important considerations.

Conclusions:

• Microscopy of fresh vaginal smears is a powerful, practical tool for diagnosing vaginal flora and associated infections.
• Further research is needed on host-pathogen interactions to understand pathogenicity.
• Accurate diagnosis is key to managing bothersome and dangerous vaginal infections.
