Bioterrorism Agent

Bioterrorism Agent


DEFINIITION:

  • Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. 
  • These agents are bacteria, viruses, fungi, or toxins, and may be in a naturally occurring or a human-modified form, in much the same way in biological warfare.
  • Sentinel laboratories are mainly involved in Control of Bioterrorism

Category A

Definition

The U.S. public health system and primary healthcare providers must be prepared to address various biological agents, including pathogens that are rarely seen in the United States. High-priority agents include organisms that pose a risk to national security because they

  • Can be easily disseminated or transmitted from person to person;
  • Result in high mortality rates and have the potential for major public health impact;
  • Might cause public panic and social disruption; and
  • Require special action for public health preparedness.

Agents/Diseases

  • Anthrax (Bacillus anthracis)
  • Botulism (Clostridium botulinum toxin)
  • Plague (Yersinia pestis)(highest potential)
  • pox (variola major)
  • Tularemia (Francisella tularensis)
  • Viral hemorrhagic fevers, including
    • Filoviruses (Ebola, Marburg)
    • Arenaviruses (Lassa, Machupo)

Category B

Definition

Second highest priority agents include those that

  • Are moderately easy to disseminate;
  • Result in moderate morbidity rates and low mortality rates; and
  • Require specific enhancements of CDC’s diagnostic capacity and enhanced disease surveillance.

Agents/Diseases

  • Brucellosis (Brucella species)
  • Epsilon toxin of Clostridium perfringens
  • Food safety threats (Salmonella species, Escherichia coli O157:H7, Shigella)
  • Glanders (Burkholderia mallei)
  • Melioidosis (Burkholderia pseudomallei)
  • Psittacosis (Chlamydia psittaci)
  • Q fever (Coxiella burnetii)
  • Ricin toxin from Ricinus communis (castor beans)
  • Staphylococcal enterotoxin B
  • Typhus fever (Rickettsia prowazekii)
  • Viral encephalitis (alphaviruses, such as eastern equine encephalitis, Venezuelan equine encephalitis, and western equine encephalitis])
  • Water safety threats (Vibrio choleraeCryptosporidium parvum)

Category C

Definition

Third highest priority agents include emerging pathogens that could be engineered for mass dissemination in the future because of

  • Availability;
  • Ease of production and dissemination; and
  • Potential for high morbidity and mortality rates and major health impact.

Agents

  • Emerging infectious diseases such as Nipah virus and hantavirus

Exam Important

Sentinel laboratories are mainly involved in Control of Bioterrorism

Category A bioterrorism agents are Ebola, Small pox, Botulism, Hemorrhagic fever, Yersinia & Clostridium botulinum

Cholera belongs to category-B of bioterrorism 

Plague carries the highest potential for use as biological weapons for microbial bioterrorism

B. anthracis is an Agent for bioterrorism
