Which one of the following correctly matches a sexually transmitted disease with its pathogen?
Syphilis - Treponema pallidum
Syphilis, a treatable bacterial disease, is caused by the bacterium Treponema pallidum. The sexually transmitted disease is often transmitted by direct contact with an open sore.
Chlamydia infection is caused by Chlamydia trachomatis. Symptoms in women may include vaginal discharge or burning with urination. Symptoms in men may include discharge from the penis, burning with urination, or pain and swelling in one or both testicles.
Gonorrhea is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. Entamoeba histolytica causes amoebic dysentery, which is not an STD, but spreads through contaminated food and water.
Urethritis is inflammation of the urethra. The most common symptom is painful or difficult urination. It is usually caused by infection with bacteria. Bacillus anthracis causes the anthrax disease, which again is not a sexually transmitted disease.
