interfaces with the challenges of killing gram-negative pathogens in a host setting, and variant gene expression and anti-gene variation by malaria parasites.
Bdellovibrio Bacteriovorus is a gram negative, obligate aerobic bacteria which preys on pathologic gram negative bacteria, thus acting as a predator in preying the periodontal pathogens like Aggregatibacter actinomycetemcomitans.
Bdellovibrio bacteriovorus is a small, curved Gram negative predatory bacteria discovered by chance in 1962 by Stolp and Petzold while they were trying to isolate bacteriophages for plant pathogenic bacteria from soil.
Bdellovibrio bacteriovorus are unable to infect mammalian cells (Simpson, 1972).
