Treponema pallidum

Treponema pallidum is a bacterium responsible for syphilis, a sexually transmitted infection. It is a spiral-shaped organism that can only survive inside the human body. The infection progresses through stages, starting with painless sores and possibly leading to more severe health issues if untreated, affecting the heart, brain, and other organs. Syphilis is typically diagnosed through blood tests and can be effectively treated with antibiotics, particularly penicillin. Early detection and treatment are crucial to preventing complications and transmission to others. It highlights the importance of regular health check-ups and safe practices in sexual health.
