The arms race of adaptation and counter adaptation in predator-prey interactions is a fascinating evolutionary dynamic with many consequences, including local adaptation and the promotion or maintenance of diversity. Although such antagonistic coevolution is suspected to be widespread in nature, experimental documentation of the process remains scant, and we have little understanding of the imp...

Bdellovibrio and like organisms are obligate predators of bacteria that are ubiquitously found in the environment. Most exhibit a peculiar dimorphic life cycle during which free-swimming attack-phase (AP) cells search for and invade bacterial prey cells. The invader develops in the prey as a filamentous polynucleoid-containing cell that finally splits into progeny cells. Therapeutic and biocont...

The objective of the present work was to evaluate novel active films made with biopolymeric matrices as carriers a living Bdellovibrio bacteriovorus HD100 strain, predatory bacterium antimicrobial potentials against pathogens. Biopolymer were prepared by casting method using following mixtures: collagen/sodium alginate/sorbitol (CA-S), alginate/glycerol (CA-G), and tapioca starch/sodium (StA-G)...
