Unsupported Conclusions on the Bacillus anthracis Spores

Unsupported conclusions on the Bacillus anthracis spores.

Douglas J. Beecher reported on the methodology that a U.S. Federal Bureau of Investigation laboratory used to identify an intentionally anthrax-contaminated letter(s) among mail collected from a Congressional building or postal facility that serves the U.S. Congress after the incident of contamination that occurred on 15 October 2001 (1). The described sampling strategy and initial screening an...

Inactivation of Bacillus anthracis Spores

After the intentional release of Bacillus anthracis through the U.S. Postal Service in the fall of 2001, many environments were contaminated with B. anthracis spores, and frequent inquiries were made regarding the science of destroying these spores. We conducted a survey of the literature that had potential application to the inactivation of B. anthracis spores. This article provides a tabular ...

Environmental Sampling for Spores of Bacillus anthracis

On November 11, 2001, following the bioterrorism-related anthrax attacks, the U.S. Postal Service collected samples at the Southern Connecticut Processing and Distribution Center; all samples were negative for Bacillus anthracis. After a patient in Connecticut died from inhalational anthrax on November 19, the center was sampled again on November 21 and 25 by using dry and wet swabs. All sample...

Environmental Persistence of Bacillus anthracis and Bacillus subtilis Spores

There is a lack of data for how the viability of biological agents may degrade over time in different environments. In this study, experiments were conducted to determine the persistence of Bacillus anthracis and Bacillus subtilis spores on outdoor materials with and without exposure to simulated sunlight, using ultraviolet (UV)-A/B radiation. Spores were inoculated onto glass, wood, concrete, ...
