Novel sample preparation method for safe and rapid detection of Bacillus anthracis spores in environmental powders and nasal swabs.

Bacillus anthracis spores have been used as a biological weapon in the United States. We wanted to develop a safe, rapid method of sample preparation that provided safe DNA for the detection of spores in environmental and clinical specimens. Our method reproducibly detects B. anthracis in samples containing <10 spores.
