1

Candida albicans, C. flabrata, and Gardnerella vaginalis, Mobiluncus spp and other anaerobes are all what?

Opportunistic microorganisms and agents of bacterial vaginosis (BV)

2

Are the BV organisms sexually transmitted?

For the most part they are not

3

Where are the BV organisms found?

In the normal flora of the vagina at any given time, but are normally present in low and harmless numbers

4

What is the key factor allowing overgrowth of Candida and the agents of BV?

Disturbance of normal flora, especially the gram positive lactobacilli but also normal flora that help maintain a low Ph and produce hydrogen peroxide

5

What is T. vaginalis?

A single cell protozoan, not a bacterium, it is considered a frank pathogen rather than a part of normal flora (it is sexually transmitted)

6

Does a single agent cause BV?

No

7

What are the agents of BV we should know?

Gardnerella vaginalis, Mobiluncus, anaerobes

8

What causes Candidiasis?

Candida albicans, C. glabrata: fungi not bacteria

9

What causes Trichomoniasis?

Trichomonas Vaginalis, a protozoan

10

What main symptoms are seen with Candidiasis, Trichomonal, and BV?

Discharge (all 3), Dysuria and itching (for C and T)

11

What is the discharge seen in Candidiasis?

Scant, white, clumped adherent plaques

12

What is the discharge seen in Trichomoniasis?

Profuse, yellow, homogenous or frothy

13

What is the discharge seen in BV?

Moderate, white or grey, adherent, homogeneous discharge that uniformly coats vagina

14

Does BV have inflammation?

No, Candidiasis and Trichomoniasis do

15

Do Candidiasis and Trichomoniasis have Leukocytes?

Yes, BV does not

16

What is cystitis characterized by?

Dysuria, suprapubic pain, polys in urine, significant numbers of bacteria in the urine

17

What is pyelonephritis characterized by?

Signs and symptoms of cystitis, significant fever, flank/back pain

18

What is Cervicitis characterized by?

Dysuria, mucopurulent discharge

19

Are BV, candidiasis, and trichomoniasis common?

Yes, very

20

How is BV diagnosed?

Foul odor (add KOH = whiff test), discharge typical a dirty white/gray, pH > 4.5 of discharge, presence of clue cells

21

How is Candidiasis diagnosed?

Vaginal itching, discharge: patchy white adherent clumps, discharge may have pungent but not foul smelling odor, pH 4.5 or below, yeasts and branching hyphae seen on wet mount w/ KOH

22

How is Trichomonas diagnoses?

Discharge: yellow-green/yellow, homogeneous and may be copious and frothy, pH > 4.5; Wet mount microscopic exam of discharge: trichomonads (size of PMNs) with twitching motility, presence of PMNs

23

How do you treat Trichomonas?

Oral metronidazole

24

How do you treat Candidiasis?

Topical and oral azoles

25

How do you treat BV?

Oral metronidazole

26

Do you treat sexual partners of Trich?

Yes, Metronidazole (not in BV or Candidiasis)
