Bdellovibrio bacteriovorus is a Gram-negative, predatory bacterium that has become one of the most significant species of the genus, so it has been taken as a reference, for a group of microorganisms like this, BALOs by its acronym in english "Bdellovibrio and like organisms". There are reports of the ability of this bacteria to prey on other Gram-negative bacteria. There is evidence within the life cycle that Bdellovibrio bacteriovorus requires the periplasmic space of Gram- negative bacteria for its survival and reproduction. However, in recent years it has been shown that they also have activity against some bacteria of the Gram-positive group, and/or in the reduction of their colonies. In different reports there is an interest to look for the range of prey, that is, the specificity or preference of the strains of Bdellovibrio spp. by one or several prisoners. McNeely et al. (2017), shows that Bdellovibrio bacteriovorus DM11 can prey on Agrobacterium tumefaciens, but Bdellovibrio bacteriovorus DM8 does not. There are some strains that can attack different prey and can have a wide range of prey, and some others seem to be very specific. The process of depredation has not been fully understood, so more in-depth studies are needed to understand these interactions.
