Figure 2
Cell morphology of L. monocytogenes strains.
Scanning electron micrographs (A) and transmission electron micrographs (B) of wild-type (Lm EGD) and Δfri mutant (Lm Δfri) cells grown in the absence or presence of penicillin G (+penG). Bars indicate 2 µm in the scanning electron micrographs and 200 nm in the transmission electron micrographs. The presented micrographs are representative of two independent sample preparations.
