Anthrax toxin is a mixture of three protein components: (i) protective antigen (PA), (ii) edema factor (EF), and (iii) lethal factor (LF). Mechanism of action. Anthrax toxin is an A-B toxin. Each individual anthrax toxin protein is nontoxic. Toxic symptoms are not observed when these proteins are injected individually into laboratory ...
Cutaneous anthrax is rarely fatal if treated, because the infection area is limited to the skin, preventing the lethal factor, edema factor, and protective antigen from entering and destroying a vital organ.
Bacillus anthracis is a Gram-positive, rod-shaped, spore-forming bacterium, and is the causative agent of anthrax, an acute, rapidly progressing infectious disease that affects both animals and humans. B. anthracis forms spores after the death of infected hosts.

Milzbrand, Bacillus anthracis, ist ein grampositives, aerobes, stäbchenförmiges Bakterium aus der Familie der Bacillaceae, das in der Lage ist, Endosporen auszubilden. Die Bakterien formen Ketten (bis zu 6 – 8 Zellen im Blut infizierter Organismen, aber sehr lange Ketten in Labormedien) und haben eine ...
Potent toxins, including edema toxin and lethal toxin, are responsible for the most severe manifestations. The main clinical forms of anthrax are cutaneous (most common), oropharyngeal, gastrointestinal, meningeal, and inhalation (most lethal). Gastrointestinal and inhalation anthrax are not transmitted from person to person.
13. Mai 2019 · In nature, the enzootic cycle of anthrax is characterized by a combination of long-term spore persistence in soil, and an obligate-lethal transmission route, primary in herbivorous mammals...
9. Mai 2024 · anthrax, acute, infectious, febrile disease of animals and humans caused by Bacillus anthracis, a bacterium that under certain conditions forms highly resistant spores capable of persisting and retaining their virulence for many years.
