Bdellovibrio bacteriovorus is a bacterium which preys upon and kills Gram- negative bacteria, including the zoonotic pathogens Escherichia coli and Salmonella. Bdellovibrio bacteriovorus is a small, curved, and highly motile Gram-negative bacteria approximately to μm wide and to μm long. Bdellovibrio bacteriovorus is a predator bacterial species found in the environment and within the human gut, able to attack Gram-negative prey. Cystic fibrosis.

Bdellovibrio is a genus of Gram-negativeobligate aerobic bacteria. Calculation of the viability of Bdellovibrio and prey cells Figure 1C Make serial dilutions of the co-cultures from 10 -1 to 10 -7 see Note 5 in DNB medium.

Bdellovibrio attacks other Gram-negative bacteria by attaching itself to the prey cell’s outer membrane and peptidoglycan layer, after bdellovibrrio it creates a small hole in the outer membrane.

These cells were Bdellovibrios. It is a known pathogen to Gram-negative bacteria, making it a possible biocontrol agent to many human pathogens.
