"Deciphering the Hunt: The Mechanism Behind Predatory Bacteria's Prey Detection"

Scientists have unraveled the mechanism by which the predatory bacteria Bdellovibrio bacteriovorus identifies and invades its prey, a question that has puzzled researchers since the 1960s. The team from the University of Birmingham and the University of Nottingham found that the bacteria use fiber-like proteins to detect and ensnare a variety of prey bacteria. This breakthrough, detailed in Nature Microbiology, could lead to the development of new antibacterial strategies, leveraging these predators to combat harmful bacteria in healthcare, food preservation, and environmental contexts.

"Deciphering the Hunt: How Predatory Bacteria Identify and Invade Their Prey"

Researchers have discovered how the predatory bacterium Bdellovibrio bacteriovorus recognizes and invades a wide range of Gram-negative bacterial hosts. It uses a family of chimeric fibre proteins, similar to phage tail fibres, with diverse adhesin domains that allow it to interact with various bacterial surfaces. These proteins are part of a large mosaic adhesive trimer (MAT) protein repertoire, which enables the predator to traverse the prey's cell envelope without causing lysis. The study also revealed that B. bacteriovorus deposits a vesicle containing these proteins into the prey's periplasm, which persists even after the predator exits, suggesting a complex mechanism of bacterial predation and potential implications for antibacterial strategies.
