Notes on Bacterial Diseases

Bacterial Diseases

• Syphilis

  • Type: Sexually transmitted disease (STD)
  • Causative Agent: Caused by the spirochete Treponema pallidum
  • Transmission:
  • Acquired through sexual contact with a partner with active lesions
  • Transfusion of infected blood
  • Transplacental inoculation of fetus by infected mother
  • Figures:
  • Figure 2-12: Secondary syphilis; features cutaneous macular lesions

• Pathogenesis of Syphilis

  • Initial contact with the spirochete leads to the formation of a hard ulcer, known as a chancre, at the infection site
  • Progression involves painless, non-suppurative regional lymphadenopathy following initial ulceration

• Other Bacterial Diseases:

  • Tuberculosis
  • Leprosy
  • Actinomycosis
  • Cancrum Oris (NOMA)
  • Gonorrhea
