This is all I could find:
Vaginal discharge is abnormal when it is excessive in amount, yellow or green in colour or foul smelling.
It may be due to infections:
- Fungus eg. thrush
- Bacteria eg. gonorrhoea, chlamydia
- Protozoa eg. Trichomonas
- Viral eg. Genital herpes, warts.

Vaginitis
Vaginitis is an inflammation of the vagina. The most common symptoms are itching burning and abnormal vaginal discharge.
Most women will experience some form of vaginitis during their life times. The most effective way to prevent vaginitis is to understand its causes and follow advice to reduce your risk.
Normal vs. Abnormal
Every woman has some vaginal discharge, and every woman's vagina contains organisms necessary to keep bacteria in normal balance. When the normal balance is upset, the vagina may be susceptible to organisms which ordinarily would be killed or controlled. The result may be an abnormal discharge which may irritate tissues, causing swelling, itching and burning of the vulva, and/or unpleasant odor.
Pelvic examinations are usually required to determine the kind of infection you may have and the proper treatment for it. There are three major types of vaginal infections, including monilia, trichomonas, and bacteria.
Monilia
Monilia, sometimes called "candida" or "yeast" is probably the most common form of vaginitis. It is caused by a fungus which does not pose any serious health hazard, but can be very annoying.
The main symptom is itching of the vagina and surrounding area, accompanied by a thick white, discharge usually having a strong odor. Although monilia is not considered to be a sexually transmitted disease, it is possible to catch monilia from your sexual partner. Uncircumcised males may harbor the fungus under the foreskin, which would look red and scaly.
Treatment
If you are experiencing symptoms of monilia, see a clinician or doctor as soon as possible.
Monilia is treated with an anti-fungal medication. This may be in the form of vaginal suppositories, creams or tablets and should always be used as prescribed.
Trichomonas Vaginalis
Often simply called "trich" (trick), this form of vaginitis is caused by single-celled organisms (protozoa), which may be found in both men and women. Trich is considered a sexually transmitted disease, but it may also be passed from person to person on washcloths, towels or bathing suits.
Trich is not as common as monilia, but the symptoms are just as annoying. Symptoms include a greenish-yellow discharge accompanied by an unpleasant odor and sometimes itching. Men usually have no symptoms.
Treatment
Treatment for trich is usually a tablet called Metronidazole or Flagyl taken orally. Both sexual partners should be treated simultaneously. To prevent re-infection, a condom should be used during sexual intercourse until treatment is complete. Re-examination after treatment is essential.
Bacterial Vaginosis
Bacterial vaginosis is caused by bacteria which normally inhabit the vagina, but under certain conditions, begin to overgrow.
Symptoms of bacterial vaginosis include a heavy, vaginal discharge having an unpleasant odor. The discharge is usually very liquid and can be irritating.
Treatment
Bacterial vaginosis is treated with antibiotic vaginal creams or suppositories and oral antibiotics.
Males may harbor these bacteria with no obvious symptoms. Check with your clinician to find out if your partner should also be treated. Condoms are recommended during intercourse to prevent reinfection and both partners should be reexamined after treatment.
Using Medication
Use all the medication as prescribed. Disappearance of the symptoms may not mean disappearance of the infection.
Check with your clinician about any other medication you may be taking. Some kinds may make your vagina more susceptible to infection. Infection spreads in moisture and heat. Keep the vulva as dry as possible.
Prevention
Poor diet, lack of sleep or the presence of other disease or infection can lower your body's resistance to vaginitis. Medications such as antibiotics, hormones and excessive douching also can increase susceptibility. Other contributing factors may include psychological factors, childbirth, cuts or abrasions, intercourse without enough lubrication and even tight-fitting clothing
If you are unsure of your sexual partner's contacts outside your relationship, insist that a condom be used during sex.
Using a condom will help prevent sexually transmitted diseases (STDS) and vaginitis. There is evidence that lamb skin condoms do not protect against STDs because the membrane is too porous; use latex condoms instead.
If you notice any genital sores or penile discharge, do not have intercourse until you and your partner have been treated.
Do not use bubble baths, feminine hygiene preparations, deodorant tampons or colored and scented bathroom tissue.
Wear white cotton underwear and change at least every 24 hours.
Always wipe from front to back after a bowel movement. Bacteria from the anal area can cause vaginitis.
Douching is usually not necessary for feminine hygiene. If you feel the need to douche, use a solution of water and vinegar.
what type of infection do i have?
