Efficacy of liquid spray decontaminants for inactivation of Bacillus anthracis spores on building and outdoor materials.

摘要: Aims:  To obtain data on the efficacy of various liquid and foam decontamination technologies to inactivate Bacillus anthracis Ames subtilis spores building outdoor materials. Methods Results:  Spores were inoculated onto test coupons positive control nine different materials. Six sporicidal liquids spray-applied remained in contact for exposure times ranging from 10 70 min. Following decontamination, recovered was quantified terms log reduction. Conclusions:  The hydrogen peroxide/peracetic acid products most effective, followed by decontaminants utilizing hypochlorous chemistry. Decontamination varied material type. Significance Impact Study:  study results may be useful selection decontaminate buildings areas event contamination with B. anthracis spores. These also facilitate decontaminant inactivation other spore-forming infectious disease agents.
