Movies
Filamentous growth and division of Bdellovibrio bacteriovorus bacteria inside an Escherichia coli prey cell. Here B. bacteriovorus produces a cytoplasmic fluorescent protein that can be detected by microscopy. The cytoplasm of the prey bacterium shrinks and fades over time as it is being digested by the predator B. bacteriovorus. The predator progeny is eventually liberated in the environment.

Escherichia coli cells grown on an agarose pad containing an antibiotic that blocks cell division, leading to a dramatic cell elongation and eventually the lysis and death of the cells
