Quick Answer

The pathogen of syphilis is the bacterium Treponema pallidum. It is a sexually transmitted infection that can also pass from mother to baby during pregnancy. Syphilis is not classified as a bloodborne pathogen, though it can rarely be transmitted through blood transfusion.

  • Treponema pallidum is a spiral-shaped bacterium, also called a spirochete.
  • Syphilis is primarily spread through direct contact with a syphilis sore during sex.
  • It is not considered a bloodborne pathogen by major health agencies.
  • Untreated syphilis progresses through primary, secondary, latent, and tertiary stages.

Understanding the pathogen behind syphilis helps clarify how the infection spreads, how it is diagnosed, and why it is treated with antibiotics. Treponema pallidum is a fragile bacterium that cannot survive long outside the human body, which is why syphilis is almost always transmitted through close physical contact. Knowing that it is a bacterium, not a virus, also explains why it is curable with penicillin. This guide covers the basics of the pathogen, how syphilis is classified, and common questions about whether it counts as a bloodborne pathogen.
