Kwang Jeon's experiment: [I] Amoebae infected by x-bacteria [II] Many amoebae become sick and die [III] Survivors have x-bacteria living in their cytoplasm [IV] Antibiotics kill x-bacteria: host amoebae die as now dependent on x-bacteria.

Candidatus Legionella jeonii is a candidatus bacterium from the genus Legionella.[3][2] Previously known as X-bacterium,[4] Candidatus Legionella jeonii grows symbiotically in Amoeba proteus.[5] This endosymbiotic relationship was first noticed by Kuang Jeon in 1966.[6][4]

A more recent reference[7] dropped "Candidatus" from its name.
