Persistence and Inactivation ofBurkholderia malleiChina 7 Deposited on Nonporous Laboratory Materials

This study evaluated the persistence of Burkholderia mallei China 7 deposited on glass, Hypalon rubber glove, and stainless steel, as well as inactivation with vaporous hydrogen peroxide fumigation of a ∼15-m3 chamber. A suspension of B mallei China 7 at ∼1 × 108 colony-forming units was dried on coupons of each test surface. One set of coupons was held at ∼20°C to 22°C and 40% to 55% relative humidity and sampled for viable B mallei at 1 hour,...
