• Bacillus anthracis
• Comes in Two forms
– Vegetative, spore
• Reproduce by asexual fission and

– Poor nutrient conditions
– Presence of oxygen
– Very resistant
– Survive for decades

4. News Reports

5. Primary Hosts

6. Ways Humans can Get it
• Cutaneous (Skin)
– Contact with infected

human infection, of which all can fit in the
area of a single pinhead.
