Description and significance
Vampriococcus is one of few known predatory prokaryotes. It is a 0.6 micrometer, ovidal bacteria of which no modal forms have been found. It is a gram-negative bacteria that is found in freshwater sulfurous lakes in northern Spain. As an anaerobic epibiont, it attaches itself to the surface of Chromatium a phototropic bacteria, by specific structures, and as it grows and devides by fission, it destroys its prey [2]. The structures used by Vampirococcus to attach itself to its prey could best be described as cytoplasmic "bridges." From these bridges, a connection is established to the prey which allows the Vampirococcus bacterium to degrade the preys cytoplasm [4]
