ABSTRACT
Bacillus anthracis, a spore-forming bacterium, is the etiologic agent of anthrax. B. anthracis spores can be aerosolized, are relatively easy to produce, and are capable of producing high mortality when inhaled. The prompt use of postexposure antibiotics combined with vaccination greatly increases the survival rate. Rapid detection of exposure is critical to effective case management. Using common collection swabs, culture medium, and culturing equipment, we compared six different noninvasive sampling sites to determine which might best be used to rapidly detect the presence of B. anthracis spores on rhesus monkeys after aerosolization. The results indicate that the greatest number of spores were deposited in the nares, on the face, and on the haired portions of the head, suggesting that these locations are the most effective sampling sites when attempting to detect B. anthracis aerosol exposure.
