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 lethality of the anthrax disease is due to the bacterium's two principal virulence factors: the poly-D-glutamic acid capsule, which protects the bacterium from phagocytosis by host neutrophils; and the tripartite protein toxin, called anthrax toxin, consisting of protective antigen (PA), edema factor (EF), and lethal factor (LF). [44]
The pXO1 plasmid (182 kb) contains the genes that encode for the anthrax toxin components: pag (protective antigen, PA), lef (lethal factor, LF), and cya (edema factor, EF). These factors are contained within a 44.8-kb pathogenicity island (PAI). The lethal toxin is a combination of PA with LF and the edema toxin is a combination of PA with EF.
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.
Anthracimycin was first noted for its potent activity against Bacillus anthracis (strain UM23C1-1), which is known to cause the human infectious disease anthrax, with a minimum inhibitory concentration (MIC) of 0.031 ug/mL.
In 1964, research programs studied Enterotoxin type B, which can cause food poisoning. New research initiatives also included prophylaxis , the preventive treatment of diseases. [ 11 ] Pathogens studied included the biological agents causing a myriad of diseases such as anthrax , glanders , brucellosis , melioidosis , Venezuelan equine ...

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.
