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.
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 ( obligate ) pathogen within the genus Bacillus .
He identified the disease, which was then called "Loodiana disease" (after the city Ludhiana) or "malignant fever," as anthrax. He reported his findings in The Veterinary Journal in 1878. [8] While identifying the anthrax bacteria from the horse blood under microscope, Griffith observed two other important pathological conditions.
Anthrax does not usually spread from an infected human to an uninfected human. [13] If the disease is fatal to the person's body, its mass of anthrax bacilli becomes a potential source of infection to others and special precautions should be used to prevent further contamination. [13] Pulmonary anthrax, if left untreated, is almost always fatal ...
Dogs are ten times more likely to be infected than humans. The disease in dogs can affect the eyes, brain, lungs, skin, or bones. [15] Histoplasmosis* is a fungal disease caused by Histoplasma capsulatum that affects both dogs and humans. The disease in dogs usually affects the lungs and small intestine. [16]
Scientists examining the anthrax from the New York Post letter said it was a clumped coarse brown granular material which looked similar to dog food. [18] Two more anthrax letters, bearing the same Trenton postmark, were dated October 9, three weeks after the first mailing.
The Sterne strain, like all Bacillus anthracis strains, has two functional 𝛃-lactamases, but gene expression is usually not sufficient to allow drug resistance. The Sterne strain acts as a good comparison to other anthrax strains, as it is a prototypical and easy to work with strain, with sensitivity to penicillin. [11]
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.
