Figure 2. Comparison of morphology of B. burgdorferi clones detected by dark-field microscopy.
Wild-type B. burgdorferi cells display a flat-wave morphology, whereas the Δbb0236 mutant exhibited a rod-shaped morphology with slight wave-like shape in the cell tips. Complemented bb0236com cells restored the morphology phenotype. Similar rod-shaped morphology of ΔflbB mutant cells was reported previously (Moon et al., 2016b).
