Candidatus Uabimicrobium is a genus of free-living aquatic Gram-negative bacteria that are known to display cell eating (phagocytosis).[1] As of 2026, there are only two species. The first species, Ca. Uabimicrobium amorphum was discovered from the Republic of Palau. Collected in 2015 and described in 2019,[2] it became the first known bacteria that can eat other microbes through phagocytosis.[3]
The second species, Ca Uabimicrobium helgolandensis was discovered from Helgoland Island, North Sea, in 2024.[4] These two bacteria with their ability to engulf and ingest (endocytosis) whole bacteria are taken as evidence of primary symbiogenesis that led to the formation of eukaryotic cells.[5][6]
