Which describes the benefit of using Bdellovibrio bacteria to control microbes? Multiple Choice Bdellovibrio bacteria harbor a bacteriophage that can lysis (kill) pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria stimulate the immune system to more accurately detect and destroy pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria are predators of Gram-negative pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria release toxins (i. e., antibiotics) to kill off or inhibit pathogens such as Salmonella spp., Shigella spp., and E. coli.
