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.
B. anthracis was the first bacterium conclusively demonstrated to cause disease, by Robert Koch in 1876. [34] The species name anthracis is from the Greek anthrax (ἄνθραξ), meaning "coal" and referring to the most common form of the disease, cutaneous anthrax, in which large, black skin lesions are formed. Throughout the 19th century ...
Anthrax is a bacterial disease that is caused by Bacillus anthracis bacteria. It can infect animals when they breathe in or ingest spores in contaminated soil, plants, or water.
Cutaneous anthrax, also known as hide-porter's disease, is when anthrax occurs on the skin. It is the most common (>90% of cases) and least dangerous form (low mortality with treatment, 23.7% mortality without). [20] [5] Cutaneous anthrax presents as a boil-like skin lesion that eventually forms an ulcer with a black center .

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]
These are animals that eat or destroy durian fruit or trees. Many of these are shot or poisoned by farmers. [6] Some of these species naturally act as seed dispersers, [7] which benefits the plant but does not benefit farmers. black hornbill (Anthracoceros malayanus) [7] squirrel [6] grey-bellied squirrel (Callosciurus caniceps) [1]
On 2 April 1979, spores of Bacillus anthracis (the causative agent of anthrax) were accidentally released from a Soviet military research facility in the city of Sverdlovsk, Soviet Union (now Yekaterinburg, Russia). The ensuing outbreak of the disease resulted in the deaths of at least 68 people, although the exact number of victims remains ...
