	Bdellovibrio - Wikipedia, the free encyclopedia
		Bdellovibrio is a genus of Gram-negative, obligate aerobic bacteria.
		Under the microscope, a Bdellovibrio appears as a comma-shaped motile rod that is about 0.3-0.5 by 0.5-1.4 µm in size with a barely discernible flagellum.
		Bdellovibrio attacks other gram-negative bacteria by colliding with them at a relatively blazing speed of 100 µm per second, which is about 100 times its size.

	A killer microbe as a living antibiotic
		Bdellovibrio bacteriovorus is a fascinating predatory bacterium that attaches specifically to certain other bacteria in order to invade them.
		Bdellovibrio can remain encysted at this stage, while the entry pore has been sealed and the prey cell remains viable.
		These attributes, together with the facts that certain Bdellovibrio strains show a very narrow prey spectrum and are capable of penetrating the same tissues as may human-pathogens, gives promise to the development of novel anti-microbial strategies.
