Thin-section EM of Francisella strain W12-1067. (A) Bacteria cultivated in medium T at 37°C possess a rod-shaped, slightly pleomorphic morphology. (B-D) Incubation of J774A.1 cells with bacteria (MOI 10). (B) Overview of host cells with two compartments containing bacteria (96 h post infection). Rectangles mark regions shown at higher magnification in C and D, respectively. (C) Two bacteria in a membrane-bound compartment. (D) Several bacteria in a compartment which shows a clearly discernible membrane at least in some regions.
