Candidatus Legionella jeonii is a candidatus species of bacteria from the genus Legionella.[2][1] Previously known as X-bacterium,[3] Candidatus Legionella jeonii grows symbiotically in Amoeba proteus.[4] This endosymbiotic relationship was first noticed by Kwang Jeon and Joan Lorch in 1966.[5][3]
A more recent reference[6] dropped "Candidatus" from its name.
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.
