Bacterial and Animal STD Infections
Gonorrhoea
In men this infection can cause burning when passing urine and a yellow discharge from the penis. Some men may have the disease without any symptoms.

In women there is often no sign of infection, but some women may have a yellow vaginal discharge, low abdominal pain, or irregular menstrual bleeding.

In both sexes infection of the rectum may follow anal sex and infection of the throat may follow oral sex. Gonorrhoea usually causes no symptoms in either of these sites.

Gonorrhoea is cured by antibiotics. If untreated, this infection can cause infertility in women and (less commonly) in men. The infection can spread to the reproductive organs in women and cause pelvic inflammatory disease (PID).

Chlamydia

This is a common infection, particularly among young sexually active people. Most people do not have any symptoms. If there are symptoms, they are similar to those for gonorrhoea.

Chlamydia is cured by antibiotics. If untreated, this infection can cause infertility in women and (less commonly) in men.

Untreated chlamydia is the most common cause of infection spreading to the reproductive organs in women (pelvic inflammatory disease).

Trichomoniasis

In women, this infection can cause an unpleasant discharge and irritation of the vagina. Antibiotics cure the infection.

Men usually do not get symptoms but may need to be treated to prevent re-infection of their partners.

Non Specific Urethritis

This occurs in men and may produce discharge from the penis or burning when passing urine.

It is an inflammation of the urethra which is not caused by gonorrhoea or chlamydia.

Although it does not cause symptoms in women, female partners of men with NSU may need to be examined if re-infection occurs.

Pubic Lice: Pediculosis Pubis

These are lice that attach to coarse body hair and cause irritation.

They are usually spread by close body contact and rarely by contact with unwashed bed linen, towels etc.
