Clostridium tetani 🧫🔬
A Gram-positive, obligately anaerobic, spore-forming bacillus and the causative agent of tetanus. Its characteristic terminal spores give the bacillus a “drumstick” or “tennis-racket” appearance.
🔬 Key laboratory features:
• Gram-positive, slender bacillus
• Obligate anaerobe
• Motile and spore-forming
• Terminal spherical spores → drumstick appearance
• Produces tetanospasmin (tetanus neurotoxin)
• Toxin interferes with inhibitory neurotransmission, producing muscle rigidity and spasms
• Spores are commonly found in soil and animal f***s
đź’‰ Prevention: Tetanus is preventable through vaccination and appropriate wound management.
