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 pathogen within the genus Bacillus. Its infection is a type of zoonosis, as it is transmitted from animals to humans. [1]
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]

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.
Anthrax vaccines are used for both livestock and human immunization. One of the most used anthrax vaccines today is based on the Sterne strain, in the form of a live-spore vaccine for animals. A vaccine with live spores is dangerous for humans, so vaccines based on the secreted toxin protein, protective antigen (PA), have been explored.
The virus causes a lethal haemorraghic disease in domestic pigs. Some strains can cause death of animals within as little as a week after infection. In other species, the virus causes no obvious disease. ASFV is endemic to sub-Saharan Africa and exists in the wild through a cycle of infection between ticks and wild pigs, bushpigs and warthogs.

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.
