Anthrax weaponization is the development and deployment of the bacterium Bacillus anthracis or, more commonly, its spore (referred to as anthrax), as a biological weapon.As a biological weapon, anthrax has been used in biowarfare and bioterrorism since 1914. [1]
Bacillus anthracis is a gram-positive and rod-shaped bacterium that causes anthrax, a deadly disease to livestock and, occasionally, to humans. It is the only permanent ( obligate ) pathogen within the genus Bacillus .
Anthrax is an infection caused by the bacterium Bacillus anthracis or Bacillus cereus biovar anthracis. [2] Infection typically occurs by contact with the skin, inhalation, or intestinal absorption. [9] Symptom onset occurs between one day and more than two months after the infection is contracted. [1]
The study showed that spores from some species can contain as much as 6.3% dry weight of silicates. [71] "For more than 20 years, significant levels of silicon had been reported in spores of at least some Bacillus species, including those of Bacillus cereus, a close relative of B. anthracis." According to spore expert Peter Setlow, "Since ...
Anthrax: Anthrax is a non-contagious disease caused by the spore-forming bacterium Bacillus anthracis. The ability of Anthrax to produce within small spores, or bacilli bacterium, makes it readily permeable to porous skin and can cause abrupt symptoms within 24 hours of exposure.
The Sterne strain, like all Bacillus anthracis strains, has two functional 𝛃-lactamases, but gene expression is usually not sufficient to allow drug resistance. The Sterne strain acts as a good comparison to other anthrax strains, as it is a prototypical and easy to work with strain, with sensitivity to penicillin.
Anthrax vaccines are vaccines to prevent the livestock and human disease anthrax, caused by the bacterium Bacillus anthracis. [1]They have had a prominent place in the history of medicine, from Pasteur's pioneering 19th-century work with cattle (the first effective bacterial vaccine and the second effective vaccine ever) to the controversial late 20th century use of a modern product to protect ...
On October 1, 2008, Michael O. Leavitt, Secretary of Health and Human Services, declared a need "to provide targeted liability protections for anthrax countermeasures" because "I have determined there is a credible risk that the threat of exposure of B. anthracis and the resulting disease constitutes a public health emergency" until the year ...
