Description

Members of the bacterial genus Bdellovibrio are obligately predacious upon other Gram-negative bacteria. Bdellovibrio are ubiquitous in nature and their prey includes plant, animal, and human pathogens. Despite the small dimensions of Bdellovibrio cells, its genome consists of 3,782,950 base pairs on a single circular chromosome. B. bacteriovorus (Bdellovibrio bacteriovorus) is a highly motile, vibrio-shaped, Gram-negative Delta-Proteobacterium and in its attack phase, it swims at high speed using a single sheathed polar flagellum with a characteristic dampened filament waveform (Ref.1). Once B. bacteriovorus has collided with a prey cell, it remains reversibly attached to it for a short “recognition” period, after which it becomes irreversibly anchored via the pole opposite the flagellum. Before invasion of the prey cell is achieved, [...]
