An absence of what may facilitate the occurrence of bacterial vaginosis?
Correct Answer: B
Rationale: Correct Answer: B - Lactobacillus acidophilus
Rationale: Lactobacillus acidophilus is a beneficial bacteria that helps maintain the acidic pH of the vagina, inhibiting the growth of harmful bacteria like Gardnerella vaginalis. An absence of Lactobacillus acidophilus can disrupt the vaginal microbiota balance, allowing for the overgrowth of harmful bacteria and leading to bacterial vaginosis.
Summary of Incorrect Choices:
A: Antibodies - Antibodies play a role in the immune response but are not directly related to the occurrence of bacterial vaginosis.
C: Gardnerella vaginalis - Gardnerella vaginalis is a bacteria associated with bacterial vaginosis, not its absence.
D: Vaginal mucosa - The integrity of the vaginal mucosa is important for protection, but its absence would not directly facilitate bacterial vaginosis.
