BACTERIAL VAGINOSIS
Bacterial vaginosis
• Non- sexually transmitted infection

• Normal vaginal flora of lactobacilli are replaced
by overgrowth of
• Gardenerella vaginalis
• Prevotella spp

• Mobiluncus spp
• Vaginal PH > 4.5
CLINICAL FEATURES
• Greyish white homogenous vaginal discharge
• Offensive fishy odor
• No vaginal inflammation
PREDISPOSING FACTORS
• Vaginal douching
• Oral sex
• Smoking
• Antibiotic use
• Recent change in sex partner
• IUCD
INVESTIGATIONS
• Microscopy
• Gram stained smear of vaginal discharge
• (presence of clue cells)
DIAGNOSTIC CRITERIA
• Presence of clue cells on microscopic examination
• clue cells are epithelial cells covered with bacteria giving
a characteristic stipped appearance on examination
• Yellowish grey discharge seen on naked eye
examination
• Vaginal pH more than 4.5
• Release of characteristic fishy odor on addition of
alkali
• 10% KOH
For diagnosis of bacterial vaginosis at least three criteria
should be present.
TREATMENTS
•Metronidazole
•400mg – 500 mg / bd for 7 days
•Or 2g stat
Non-infective causes of vaginal
discharge
• Retained foreign bodies
• Foul-smelling discharge
• Cervical polyps
• Intermenstrual bleeding
Case scenario 1
• 27 year old female, presenting with a
mucopurulent vaginal discharge for 1 day, also
complains of dysuria,lower abdominal pain and
post coital bleeding. She has a recent history of
having unprotected sex.
Case scenario 2
• 27 year old female, presenting with a profuse
frothy yellow/gray discharge with foul odor for 1
day also complains of dysuria, vulval itching and
dyspareunia. She has a recent history of having
unprotected sex.
Case scenario 3
• 25 year old female, presenting with a thick curdy
vaginal discharge for 1 day, also complains of
external dysuria, vulval itching & soreness.
Case scenario 5
• 33 year old female, presenting with a creamy
vaginal discharge with a fishy odor for 2 days, no
vulval itching or soreness.
