Inactivation of vegetative bacterial threat agents on environmental surfaces

Inactivation of Burkholderia pseudomallei on environmental surfaces using spray-applied, common liquid disinfectants

“…However, consistent with previous studies, carpet, concrete and wood were more difficult to decontaminate than the hard, nonporous materials such as glass and aluminium (Calfee et al . ; Calfee and Wendling ). Oxidizing decontaminants, such as bleach, often demonstrate reduced effectiveness on organic‐rich materials such as wood (Wood et al .…”

Do we know how best to disinfect child care sites in the United States? A review of available disinfectant efficacy data and health risks of the major disinfectant classes

“…Other complicating factors regarding the effectiveness of a disinfectant include not only the chemical used but also the concentration, 97 technique (ie, contact time), 98 surface type, 15,99 presence of organic soiling, 100,101 and pathogen. 102,103 Porous materials, in particular, are more difficult to disinfect than nonporous surfaces, 15,46,104 and EPA certification does not certify efficacy on porous surfaces. Many of these factors would be difficult for child care providers to control; however, using products that can achieve disinfection in a shorter contact time is a practical change that could reduce exposure and increase correct use.…”

Putting the Jigsaw Together - A Brief Insight Into the Tularemia

“…Generally, it can be said that chlorine dioxide in all chemical states is the disinfecting agent of first choice. Among other disinfectants, chlorine dioxide was tested using a spray-based application method on several environmental surfaces (aluminum, carpet, concrete, glass, and wood coupons) [260], its gaseous form was tested for the decontamination of hospital rooms [261], and a chlorine dioxide solution in potable water was tested for the efficacy to inactivate bacterial threat agents [262].…”

“…Experimental results have documented that decontamination efficacy is dependent upon the ambient temperature and porosity of the surfaces to be decontaminated. Woody surfaces and carpets are particularly difficult to decontaminate [260]. Moreover, the number of bacteria in the area to be decontaminated, the solution from which the agent was dispersed (proteinaceous coating can stabilize bacteria against the effect of external influences including chemical treatment), and the possible unexpected expansion of the agent can complicate decontamination.…”
