Multiple Choice

What changes might occur in the vagina if lactobacilli were eliminated?

• C) There would be no change in the health of the woman-other members of the normal flora would 'fill in the gap' in the population, resulting in no overall change.
• D) The acidic pH might change to a more neutral (and pathogen-fostering) level AND lactobacilli often produce the anti-anaerobic bacteria compound hydrogen peroxide. Without it, anaerobic pathogens might cause disease states (e.g. gas gangrene).
