Category A agents are listed below: • Anthrax (Bacillus anthracis) • Botulism (Clostridium botulinum toxin) • Plague (Yersinia pestis) • Smallpox (variola major) • Tularemia (Francisella tularensis) • Viral hemorrhagic fevers (filoviruses [e.g., Ebola, Marburg] and arenaviruses [e.g., Lassa, Machupo]) Category B Agents dangerous. The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. How to use this tool How to use this tool. Biological agents are relevant to many trades and occupations, and a sizeable portion of the working population faces the risk of exposure. Biological agents are stored and transported in robust leak-proof containers with uncontaminated external surfaces. Address the moral and ethical implications arising from the use of biological agents in combat or acts of terrorism. What are Category C biological agents? Sulfur mustard (H) (mustard gas) Lewisites/chloroarsine agents. Refrigerators and freezers containing hazardous biological agents should be locked. Provide one biological agent example from each category, and explain personal safety defenses that may be deployed against this agent. Mustards. Categories B and C Agents •Cat B Agents –Moderately easy to disseminate –Moderate morbidity, low mortality –Require enhancement of current diagnostic/laboratory capabilities and enhanced surveillance •Cat C Agents –Emerging pathogens thought to have potential. fungi. The Three Categories of Biological Weapons The CDC separates potential bioterrorism agents that cause infections in humans into three categories, designated as A, B, and C [source: http://www.bt.cdc.gov/Agent/agentlist.asp, accessed 4/7/03].
