Chancroid is a sexually transmitted disease caused by infection with the bacterium Haemophilus ducreyi. This organism causes one or more ulcers on the genitalia and are associated with inguinal lymphadenitis. The affected lymph nodes may progress towards abscess formation. Co-existent infection with other organisms e.g. Herpes simplex, Treponema pallidum and Chlamydia trachomatis is common. The chancroid appears within few hours as a pustule with rapidly ulcerate. The ulcer is yellow, irregular and the discharge is free and purulent.

Gonorrhoea is a venereal disease caused by the bacteria Neisseria gonorrhoeae. There is white, yellow or green discharge from the orifice of the penis and a feeling of pain during the act of urination along with inflamation of the penis. The disease most frequently affects 15 to 25-year-olds, although the number of cases has fallen in recent years.

Syphilis is a sexually transmitted infection (STD) caused by a spirochaete bacterium, Treponema pallidum. Syphilis has many alternate names, including “syph”, “the Pox” (or “great pox”, to distinguish it from smallpox), “lues” (hence luiphobia, or fear of syphilis), and the “freedom disease.”

The route of transmission of syphilis is almost invariably by sexual contact; however, there are examples of direct contact infections (see yaws) and of congenital syphilis (transmission from mother to child in utero).
