Anthrax toxin is a three-protein exotoxin secreted by virulent strains of the bacterium, Bacillus anthracis—the causative agent of anthrax. The toxin was first discovered by Harry Smith in 1954. [ 1 ]
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]
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 was an infection that involved several very important medical developments.
Robert Koch is widely known for his work with anthrax, discovering the causative agent of the fatal disease to be Bacillus anthracis. [20] After officially becoming a district physician in Wollstein (today's Wolsztyn), Poland, in 1872, Robert began to delve into the disease called Anthrax.
This protein has been shown to also be a docking protein or receptor for Bacillus anthracis toxin, the causative agent of the disease, anthrax. The binding of the protective antigen (PA) component, of the tripartite anthrax toxin, to this receptor protein mediates delivery of toxin components to the cytosol of cells.
A culture of Bacillus anthracis, the causative agent of anthrax. Biological agents, also known as biological weapons or bioweapons, are pathogens used as weapons. In addition to these living or replicating pathogens, toxins and biotoxins are also included among the bio-agents. More than 1,200 different kinds of potentially weaponizable bio ...
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.
A potent three-protein virulence factor produced by Bacillus anthracis, called anthrax toxin, plays a key role in anthrax pathogenesis. Exotoxins are extremely immunogenic and trigger the humoral response (antibodies target the toxin). Exotoxins are also produced by some fungi as a competitive resource.
