Biological Efficacy of the Joint Biological Agent Decontamination System, Interior-Decontamination Capability (JBADS Lite)
Abstract
This study evaluated microorganisms with varying levels of resistance to disinfection and provides data to expand the utility of the JBADS process. Protocols were established for preparing biological indicators (BIs) containing various microorganisms to compliment JBADS field testing efforts. The BIs were qualified in terms of concentration, stability, and resistance to a range of Biothermal Decontamination (BTD) treatments under controlled laboratory conditions. Estimated the kill rates of the BIs at various BTD conditions ranging in dew points from 50 to 139 F were determined. Laboratory efficacy results provided a basis for estimating minimum target dew points or equivalent temperature and humidity conditions needed to achieve a 4-log reduction (LR) within 8 hours for each type of pathogen. Thereafter, BIs were incorporated in two JBADS Lite field demonstrations to assess the effectiveness of the BTD treatment. The kill rates generated for the diverse types of BIs in this study can be used as an aid in selecting the decontamination cycle (time, temperature, and relative humidity) to achieve a desired LR for a given type of pathogen using the JBADS Lite.
