Researchers have identified a section of the anthrax toxin Lethal Factor that could help produce a more effective vaccine. Anthrax is a potentially lethal disease caused by a bacterium called Bacillus anthracis. The bacteria produce spores that when inhaled, ingested or absorbed into the skin release toxins. When anthrax affects the lungs or intestines it can cause death within a few days whilst infection of the skin (cutaneous anthrax) is less dangerous.
