Mycobactericidal efficacy of sporicidal wipes

The chlorine dioxide-based disinfectant wipes were effective against the microorganism in just 30 seconds. Tristel sporicidal wipes were assessed using a modified version of the European Standard prEN 14563 carrier test against M. avium, which provided close simulation of actual usage conditions. The wipes kill all organisms on precleaned surfaces from which soil and organic matter have been removed.

The new research is unique in that it is the only study in which chlorine dioxide mycobactericidal activity has been assessed in vitro on a carrier test, and it is the first to use the new European Standard prEN 14536 to do so. The use of the standardised procedure is significant as it minimises mycobacterial aggregation during the suspension procedure, which can lead to spurious disinfection resistance and variable colony counts.
