Δndh and ΔndhΔnuoAN have a late growth defect in macrophages. J774 macrophages were infected at an MOI (multiplicity of infection) of 1 with CDC1551 or the NADH dehydrogenase mutants. At 1, 2, and 4 d postinfection, macrophages were lysed and plated to determine bacterial cfu. The complemented strains Δndh pMV361::ndh and ΔndhA pMV361::ndhA are shown as Δndhc and ΔndhAc, respectively. The average of two independent experiments done in duplicate is shown with SD.
