Anthrax is an infection caused by the bacterium "Bacillus anthracis". Also interesting is the effect of alpha-defensins on the exotoxin produced by anthrax ("Bacillus anthracis"). This enzyme is a component of the lethal factor produced by the bacterium "Bacillus anthracis". Anthrax is an acute disease caused by the bacterium "Bacillus anthracis". Experimental studies also established that the species is capable of mechanical transmission of "Bacillus anthracis". Endospores of the bacterium "Bacillus anthracis" were used in the 2001 anthrax attacks. He demonstrated that the novel compound was effective against the deadly anthrax bacterium, "Bacillus anthracis". NLRP1 recognizes lethal toxin from "Bacillus anthracis" and muramyl dipeptide. One of their current subjects is reportedly "Bacillus anthracis" strain H-4. In 1876, Robert Koch had shown that "Bacillus anthracis" caused anthrax. The lethal factor protease is produced and secreted by "Bacillus anthracis", the agent of anthrax. VCC has also been applied to "Bacillus anthracis", the causative agent of anthrax. Some specific species include "Klebsiella oxytoca", "Citrobacter freundii", and "Bacillus anthracis". For example, "Bacillus anthracis" is considered an effective agent for several reasons. Other important Gram-positive causes of pneumonia are "Staphylococcus aureus" () and "Bacillus anthracis".
