Scientists uncover 'secret to success' of bacterium that preys on salmonella

Employees of the universities of Nottingham, Birmingham and Newcastle proved that the curved shape of a bacterium in the form

boomerang Bdellovibrio bacteriovorus affects herthe ability to prey on, effectively invade, grow, and live inside other bacteria. A special protein Bd1075 is responsible for its creation. Its bacterium uses itself (and does not secrete into prey). Without it, the curved form of Bdellovibrio bacteriovorus disappears.

In a new study, researchers also foundthat the gene that modifies the bacterial cell wall has unique properties. They allow bacteria to form their distinctive shape.

Previously, researchers found that the bacteriumcan invade the victim's cells without harming itself. All due to the fact that she gives the victim the shape of a sphere using special proteins. Bdellovibrio secrete them to change the cell walls of the attacked organism.

Bdellovibrio bacteriovorus - speciesGram-negative predatory bacteria. These organisms are of particular interest to scientists due to their ability to control the growth of bacterial populations without the use of antibiotics. For example, she preys on E. coli and salmonella.
