Efficacy of sporicidal wipes for inactivation of a Bacillus anthracis surrogate

摘要: Aims To evaluate five commercially available sporicidal wipes and two disinfecting for their ability to inactivate Bacillus atrophaeus spores deposited onto various material surfaces. Methods Results Decontamination efficacy of the was initially tested on glass Petri dishes (150 mm diameter). Following exposure a specified time contact, survival assessed by quantification remaining viable spores, both coupon surface towelette itself, with quantified in terms mean log reduction. Based these data, were down-selected evaluation larger scale, using 36 × 36 cm coupons different types. Conclusions Results suggest that sodium hypochlorite-based most effective, having completely inactivated dish several materials. Additionally, results demonstrate manufacturer-prescribed contact times Clostridium difficile achieved 6 log10 reduction B. atrophaeus spores. Moreover, not able kill as evaluated. Significance Impact Study These data show potential decontamination small, contained areas biological contamination may help on-scene coordinators develop remediation plans following terrorism event.
