Clostridium
Spores Ø Clostridium form endospores under adverse environmental conditions Ø Spores are a survival mechanism Ø Spores are characterized on the basis of position, size and shape Ø Most Clostridium spp. , including C. perfringens and C. botulinum, have ovoid subterminal (OST) spores Ø C. tetani have round terminal (RT) spores
Clostridium Associated Human Disease
Clostridium perfringens
Summary of C. perfringens Infections
Micro & Macroscopic C. perfringens NOTE: Large rectangular gram-positive bacilli NOTE: Double zone of hemolysis Inner beta-hemolysis = θ toxin Outer alpha-hemolysis = α toxin
Summary of C. perfringens Infections (cont. )
Clostridial Cellulitis
Minor Major C. perfringens Virulence Factors
Exotoxins Associated with C. perfringens Types A-E Major
C. perfringens Nagler Reaction NOTE: Lecithinase (α-toxin; phospholipase) hydrolyzes phospholipids in egg-yolk agar around streak on right. Antibody against α-toxin inhibits activity around left streak.
Clostridium tetani
Summary of C. tetani Infections
