Q

Bacillus anthracis Characteristics
Spore-Forming Bacilli

A
  • Rod Shaped
  • Endospore
  • Gram-Positive: cell wall is thick; purple when stained; killed by penicillin
  • Obligate Aerobic: microorganisms that can only live in the presence of oxygen, because they need oxygen to metabolize sugars
  • Single or in chains
  • Non-motile

Q

Clostridium perfringens Diseases
Spore-Forming Bacilli

A
  • Gas Gangrene/Myonecrosis: Bacteria gather in an injury or surgical wound that has no blood supply.
    The bacterial infection produces toxins that release gas and cause tissue death (antemortem)
  • Tissue Gas: Postmortem form of tissue gas; can spread through instruments
  • Food Poisoning
