“Background Burkholderia (B.) pseudomallei and B. mallei are genetically closely related bacterial species that can cause fatal disease in humans and animals. B. pseudomallei is a facultative intracellular soil bacterium and the cause of melioidosis, which has the highest prevalence in the hot and humid regions of Southeast Asia, and Northern Australia. The infection can be acquired by contact with contaminated soil or water by inhalation or percutaneously.
