Figure 2From: Chitobiose utilization in Borrelia burgdorferi is dually regulated by RpoD and RpoSMorphology of B. burgdorferi during GlcNAc starvation. Phase contrast microscopy of B. burgdorferi strain B31-A at 400× (A and B) and 1000× (C and D). Spirochetes were cultured for 72 h in BSK-II with GlcNAc (A and C) and without GlcNAc (B and D).Back to article page
