Which biological agent is a virus?
Biological agents are widely found in the natural environment and as a result found in many work sectors. They include bacteria, viruses, fungi (including yeasts and moulds) and internal human parasites (endoparasites). The majority of these agents are harmless however some may have potential to cause ill health.
Which are the potential agents in biological warfare?
- Anthrax (Bacillus anthracis)
- Botulism (Clostridium botulinum toxin)
- Plague (Yersinia pestis)
- Smallpox (variola major)
- Tularemia (Francisella tularensis)
- Viral hemorrhagic fevers, including. Filoviruses (Ebola, Marburg) Arenaviruses (Lassa, Machupo)
What is the most dangerous biological agent?
Bacillus anthracis bacteria, which causes anthrax, is one of the most deadly agents to be used as a biological weapon. It is classified by the US Centres for Disease Control and Prevention (CDC) as a Category A agent, posing a significant risk to national security.
What are virus agents?
A virus is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria.
Is a virus a biological agent?
Biological agents include bacteria, viruses, fungi, other microorganisms and their associated toxins. They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious medical conditions—even death.
Are all viruses harmful?
When you think of viruses, the yearly flu or even the Ebola or Swine flu outbreaks may come to mind. However, not all viruses cause disease – some even provide cures! Adeno-associated virus (AAV) can infect humans, but is not known to cause disease.
What’s the difference between disease and virus?
Viruses are smaller than bacteria. Bacteria can survive without a host, although a virus can’t because it attaches itself to cells. Viruses almost always lead to diseases (at a much higher rate than bacteria).
What are the six biological agents?
Along with smallpox, anthrax, plague, botulism, and tularemia, hemorrhagic fever viruses are among six agents identified by the Centers for Disease Control and Prevention (CDC) as the most likely to be used as biological weapons.
Where can biological warfare agents be found in the world?
Seed stocks for biological agents are readily available in the natural environment and from culture collections in the industrialized and in some devel-oping nations. The recent outbreaks of Ebola in Africa and Hanta virus infections in Asia and North and South America are evidence of this.
What are the stages of biological warfare production?
The stages involved in the production of biological agents include selection of the organisms, large-scale production of organisms from small starter cultures, and stabilization of the organisms.
How are gene probes used in biological warfare?
Gene Probes – These are polynucleotides that are 20-30 units bend, under stringent conditions, complementory nucleic acid fragments characteristic of biological agents. These units provide the basis of rapid detection and identification.
How many people are involved in Russian biological warfare?
Tens of thousands of scientists, researchers, doctors, engineers, technicians, and military personnel were involved in this effort, and currently in Russia there are hundreds of covert laboratories, testing facilities and production centers that complement the capabilities it uses to bring back to life the Soviet concept of biological warfare.
