Would Bdellovibrio bacteriovorus attack staphylococcus aureus?

Answer 1

Unfortunately not! Bdellovibrio are only able to prey upon Gram-negative bacteria, ie cells with both a cell wall and an outer membrane layer, as they grow in the area between the two. Gram-positive bacteria such as Staphlococcus aureusonly have a cell wall, (which is different to those in Gram-negative bacteria), and no outer membrane, so Bdellovibrio cannot eat them.

Bdellovibrio can prey on many Gram-negative pathogenic bacteria, including E. coli, Salmonella and Pseudomonas.

Answer 2

Yes, Bdellovibrio bacteriovorus is a predatory bacterium that attacks and feeds on other bacteria, including Staphylococcus aureus. This predatory behavior makes Bdellovibrio a potential candidate for controlling bacterial infections.
