Fig. 4: Different cell morphologies of D. mccartyi strain BTF08 cells.

Electron micrograph of D. mccartyi BTF08 in pure culture (A) and in co-culture with S. multivorans (B, C), where D. mccartyi BTF08 exhibits the hitherto unknown barrel-like morphology. White arrows indicate flagella and yellow arrows indicate ring-shaped septum of D. mccartyi cells.
