The present study compares the efficacy of various disinfectants against Bacillus
anthracis spores. While Bleach Rite® and 10% bleach reduce spore numbers by 90% within 10
minutes, a long contact time is required for complete disinfection. By contrast, although
SporGon® did not initially reduce the number of spores as quickly as Bleach Rite or 10%
bleach, shorter contact times were required for complete eradication of viable spores.
