Study Notes
Cutaneous Anthrax
- Bacillus anthracis is associated with cutaneous anthrax.
- Cutaneous anthrax is a common type of anthrax.
- It develops after the bacteria enters through a cut or abrasion.
Bacillus Species
- Bacillus species are non-branching, catalase-positive, gram-positive bacilli.
- The characteristic enzyme of Bacillus species is catalase.
- The enzyme catalase breaks down hydrogen peroxide into water and oxygen.
- The group containing Bacillus species currently comprises 32 genera.
- Bacillus is the most medically relevant organism in the group.
Anthrax Transmission
- Bacillus anthracis produces endospores.
- These endospores are highly resistant to environmental conditions and can be transmitted through contact with infected animals or contaminated materials.
- The endospores enter the body through cuts or abrasions in the skin.
