A section of the anthrax toxin Lethal Factor that could help produce a more effective vaccine, researchers report. Anthrax is a potentially lethal disease caused by a bacterium. 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. Infection can occur from contact with infected livestock, meat or hides, but most people know about anthrax from its use as a biological weapon, notably in the 2001 attacks through the US postal system.
