  1. Bio II Do Now Please copy the following information into your notes: Anthrax Causative organism: Bacillus anthracis, gram + aerobe Infection method: Spores (not person-person) Natural hosts: herbivores (cattle, sheep, etc.) Disease: lungs, skin, or digestive tract, depending on exposure. Biological Warfare: Dangerous bio-weapon responsible for 2001 anthrax attacks in US

  2. Not these guys…

  3. SPORES! • Spores are like bacteria seeds. They are tough, inactive cells that can survive for decades or centuries. Many Bacillus species form spores

  4. Disease Method: exotoxins • Bacillus anthracis produces toxic chemicals that kill nearby cells Cutaneous (skin) anthrax

  5. Inhalation anthrax

  6. Biological Warfare • Studied and used by US, UK, USSR, and German armies in the past. • Weaponized versions are antibiotic resistant, highly deadly, and have fine spores that stay airborne for long periods of time.

  7. Terrorist Threat • The US anthrax attacks of 2001 used a military weapon strain from an Army research lab. 5 people were killed in what was the most extreme example of domestic bio-terrorism to date.
