Figure 9: Transmission electron micrographs showing prey ghost structures from different bacteria after 24 h predation by mutant Bdellovibrio.

Samples of ghosts were treated with final concentrations of 0.1% SDS or 100 μgml−1 lysozyme/10 mM EDTA. Double = ∆bd0468∆bd3279 mutant strain, Quadruple = ∆bd0468∆bd3279∆bd0816∆bd3459 mutant strain. E = Escherichia, A = Acinetobacter, P = Pseudomonas. Scale bars are 500 nm.
