Latest Anthrax Stories
A new hypothesis concerning a crucial step in the anthrax infection process has been advanced by scientists at the National Institute of Standards and Technology (NIST) and the U.S. Army Medical Research Institute for Infectious Diseases (USAMRIID) at Fort Detrick, Md.
Scientists writing in the journal Angewandte Chemie say they have discovered a new chemical compound from an ocean microbe that could open up new treatments for anthrax and other ailments.
Bacillus anthracis is a Gram-positive spore-forming, rod-shaped bacterium, with a width of 1-1.2Âµm and a length of 3-5Âµm. It can grow in aerobic or anaerobic conditions. It is the only known bacterium to synthesize a protein capsule and the only pathogenic bacterium to carry its own adenylyl cyclase virulence factor. They form oval spores located centrally in a non-swollen sporangium. These spores are highly resilient and can survive extreme temperatures, low-nutrient environments, and...
