Survival of Burkholderia pseudomallei on Environmental Surfaces

摘要

The survival of the biothreat agent Burkholderia pseudomallei on the surfaces of four materials was measured by culture and esterase activity analyses. The culture results demonstrated that this organism persisted for <24 h to <7 days depending on the material, bacterial isolate, and suspension medium. The persistence determined by analysis of esterase activity, as measured with a ScanRDI solid-phase cytometer, was always longer than the persistence determined by culture analysis.
