infection, we first compared the survival of B. pseudomallei with its closely related non-pathogenic bacteria B. thailandensis in activated (50 U/mL IFN-γ) RAW264.7 macrophages stably transfected with wild-type (Nramp1+) or mutant (Nramp1−) Nramp1 (White et al., 2004). Here, IFNG is linked to infection.
