Q

What is the most important mechanism of pathogenesis for Gonorrhea? Name some of sx of gonorrhea

A

Pilli! allows for adherence to mucosa so it can evade phagocytosis
When you stick your pilli in bad places, you’re going to need a pil(i) to make you feel better
Sx: Abdominal pain and discharge

Q

Describe the evolution of the vaginal epithelium? i.e. how it begins, how it ends, where it comes from etc…

A

The lower 1/3 of the vaginal epithelium, which is squamous epithelium, is derived from the urogenital sinus. The upper 2/3 of the vaginal epithelium is derived from the Mullerian ducts. The squamous cells grow upward and take over the upper 2/3 of the vaginal epithelium
