In September 2001, letters containing anthrax spores were mailed to several news media offices and two U.S. Senators, killing five people and infecting 17 others. Of those infected, 11 developed cutaneous anthrax, while 11 developed inhalation anthrax. 20 of the 22 infected worked at a site where contaminated mail was handled or received. [7]
The fine powder anthrax sent to Daschle and Leahy mostly caused the more dangerous form of infection known as inhalational anthrax (8 out of 10 cases). Postal worker Patrick O'Donnell and accountant Linda Burch contracted cutaneous anthrax from the Senate letters.
Anthrax meningoencephalitis is also nearly always fatal. [72] Gastrointestinal anthrax infections can be treated, but usually result in fatality rates of 25% to 60%, depending upon how soon treatment commences. Injection anthrax is the rarest form of anthrax, and has only been seen to have occurred in a group of heroin injecting drug users. [70]
Anthrax is a disease caused by Bacillus anthracis, a spore-forming, Gram positive, rod-shaped bacterium (Fig. 1).The lethality of the disease is caused by the bacterium's two principal virulence factors: (i) the polyglutamic acid capsule, which is anti-phagocytic, and (ii) the tripartite protein toxin, called anthrax toxin.
The Anthrax Attacks is about the 2001 anthrax attacks and the ensuing FBI investigations into it. In a biological attack that started one week after the September 11 attacks, five people were killed and at least 17 people were injured. [1]
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 ]
The leakage of anthrax hit the ceramics factory, south of Compound 19, the hardest. The factory, which employed 2,180 personnel, was in possession of a ventilation system which sucked air from the outside, directing some to the furnaces with the remainder being directed to the workforce. In the coming weeks at least 18 workers at the factory died.
Biological sabotage in the form of anthrax and glanders was undertaken on behalf of the Imperial German government during World War I (1914–1918), with indifferent results. [36] The Geneva Protocol of 1925 prohibited the first use of chemical and biological weapons against enemy nationals in international armed conflicts.
