Name some natural defences of the female genital tract
• 1) Anatomical Features– Simple squamous epithelium in vagina– Associated skin folds (labia major + minor)– Cervix is a physical barrier to most infections from ascending to uterus +
oviducts• 2) Normal microbial flora• 3) Acid environment (pH 5)
– Maintained by lactobacilli (major defence)– Vaginal epithelium produces glycogen in response to circulating E– Lactobacilli metabolise glycogen to lactic acid ¯pH
• 4) Cervical mucus– Antibacterial activity + contains lysozyme
• 5) Ciliated cells of uterus– Constantly drive mucous towards natural orifices carrying with it any bacteria
• 6) Regular menstruation

What are 4 ways to detect pathogens?
• 1. Selective media (organisms that grow)• 2. NAAT for organisms that do not grow well or
are non-cultivable & have conserved DNA/RNA• 3. Serology (for organisms that produce an
antibody response)• 4. Microscopy (IF, special stains, wet mounts as
indication and for visible but noncultivable organisms)

True or false?
• Ectopic pregnancy - Produces pain only with acute dilatation of the tube, if the tube ruptures pain is relieved a little and is replaced by generalized pelvic and abdominal pain as the haemoperitoneum develops
• Functional cysts (follicle, corpus luteum) rupture less readily than do benign or malignant neoplasms

What can cause this sort of pain?
• Acute onset of bilateral lower abdominal pain that increases with movement, fever, purulent vaginal discharge
• Pain often associated with menses• Direct and rebound tenderness, cervical
motion tenderness and bilateral adnexal tenderness
PID

Give a brief summary of the immunology of HIV
• HIV binds to gp120 glycoprotein, to CD4 receptors on helper T lymphocytes, monocytes, macrophages, and neural cells
• CD4+ cells migrate to lymphoid tissue where the virus replicates release and in turn infect new CD4+ cells
• As infection progress depletion or impaired function of CD4+ cells decrease immune function
