COVER

Predatory Bdellovibrio bacteriovorus bacteria invade the periplasm of other Gram-negative "prey" bacteria.

Issue Image

The action of predatorily specialized, PBP4-like peptidoglycan-endopeptidase enzymes of Bdellovibrio modifies and rounds the prey cell wall. This prevents wasteful double invasion of already occupied prey bacteria by subsequent Bdellovibrio. Electron microscopy shows two predatory Bdellovibrio bacteria outside of two rounded E. coli prey "bdelloplasts" previously invaded by the crescent-shaped Bdellovibrio seen within. Cells were negatively strained with phosphotungstic acid (see Lerner et al., doi:10.1371/journal.ppat.1002524).
