Melioidosis is a fatal infectious disease caused by the Tier 1 Select Agent Burkholderia pseudomallei. Hallmarks of melioidosis include pneumonic disease and prominent septicaemic spread. Both forms of disease are contingent upon the bacterium’s intracellular life cycle and particularly on its ability to escape from host cell phagosomes. Upon encountering a host cell, B. pseudomallei is internalized into membrane-bound vacuoles from which the bacterium must rapidly escape to the cytoplasm in order to replicate and promote its survival. In the host cytoplasm, B. pseudomallei is capable of polymerizing actin for intracellular and intercellular motility and spread, lysing the host …
