Anthrax. Anthrax is the disease caused by the bacterium Bacillus anthracis, which lives in soil. The bacterial cell lives as a hardy spore to survive harsh conditions. The spores germinate into thriving colonies of bacteria once inside an animal or person.hen a person inhales the spores of Bacillus anthracis, they germinate and the bacteria infect the lungs, spreading to the lymph nodes in the chest. As the bacteria grow, they produce two kinds of deadly toxins.
Figure 1. Electron micrograph of the anthrax causing bacteria, Bacillus anthracis. Anthrax toxin is a three-protein exotoxin secreted by virulent strains of the bacterium, Bacillus anthracis âthe causative agent of anthrax.The toxin was first discovered by Harry Smith in 1954.Anthrax toxin is composed of a cell-binding protein, known as protective antigen (PA), and two enzyme components, called edema factor (EF) and lethal factor (LF). These three protein components act together to impart their physiological effects.nterestingly, each individual anthrax toxin protein is, in fact, nontoxic. Toxic symptoms are not observed when these proteins are injected individually into laboratory animals. However, the co-injection of PA and EF causes edema, and the co-injection of PA and LF is lethal.
