Question Vaginal tissues resist candidiasis by which mechanism?

A 29-year-old woman complains of vaginal burning, erythema, and a white, curdlike discharge consistent with a Candida infection. Vaginal tissues resist mucocutaneous candidiasis by which primary mechanism?

a) Cilia on epithelial cells move in the direction of the vaginal orifice
b) Glands in the submucosa of the vagina secrete lysozyme onto the vaginal surface
c) Vaginal epithelium has an acidic surface
d) Vaginal epithelium has a well-developed basement membrane
e) Vaginal epithelium is stratified and keratinized

Correct Answer correct answer :)

The answer is c) Vaginal epithelium has an acidic surface

Vaginal epithelial cells have abundant glycogen. Glycogen is converted easily to glucose and glucose to lactic acid, which maintains an acidic environment that is protective against Candida. Lactobacilli are important in the production of lactic acid.

As for E) - The vaginal epithelium is stratified, but it is not keratinized.
