A 40-year-old woman with gray, runny vaginal discharge that has a foul, fishy odor has been told that she most likely has vaginosis. Which of the following phenomena most likely contributed to her present condition?
A)
Unprotected sex with a new partner who is a carrier of the relevant bacteria.
B)
Autoinoculation from a cold sore, wart, or oral fungal infection.
C)
A sharp reduction in the number of lactobacilli in the client's vaginal flora.
D)
Proliferation of sexually transmitted protozoa.
Ans:
C
Feedback:
Vaginosis is a disorder characterized by a shift in the vaginal flora from one dominated by hydrogen peroxide-producing Lactobacillus to one with greatly reduced numbers of Lactobacillus species and an overgrowth of other organisms. Autoinoculation or sexual transmission of bacteria or protozoa is unlikely to contribute.
