Bdellovibrio life cycle is described as:
- Due to its high speed of movement, the Bdellovibriorams the target cell
- It quickly attaches to the host cell envelope by its non-flagellated end, presumably drilling into the host cell wall.
- A hole appears in the host’s cell wall at the site of attachment and the parasite invades the host periplasm. The flagellum is lost during penetration and remains outside the host.
- The Bdellovibriogrows with multiple copies of the genome.
- As the food supply becomes exhausted, the filament divides by multiple fission, splitting into several new Bdellovibrio bacteria.
- The host cell swells, ruptures and the Bdellovibrio new cells are liberated.
