The bacterium Treponema pallidum is responsible for which sexually transmitted disease?

Explanation

Treponema pallidum is the spiral bacterium, or spirochaete, that causes syphilis, a disease progressing through primary, secondary, latent and tertiary stages over many years if untreated. Gonorrhoea is caused by the diplococcus Neisseria gonorrhoeae and chlamydia by Chlamydia trachomatis. Genital herpes is viral and therefore not treatable with antibiotics at all.
