Impact of Fusobacterium nucleatum in the gastrointestinal tract on natural killer cells

Figure 1 Effects of Fusobacteriumnucleatum, Peptostreptococcusanaerobius, and Parvimonasmicra on natural killer cells in vitro. Natural killer 92 cells were cultured for 24 or 48 h with each organism at a multiplicity of infection of 100:1, 250:1 or 500:1. Post-incubation, viability in the cultures was assessed using trypan blue staining. A: Fusobacterium nucleatum; B: Peptostreptococcus anaerobius; C: Parvimonas micra. F. nucleatum: Fusobacterium nucleatum; P. anaerobius: Peptostreptococcus anaerobius; P. micra: Parvimonas micra.
