The population structure of Korean (150 strains) and Japanese (92 strains) Legionella pneumophila isolates along with 18 reference strains were investigated using hsp60 sequence (1647 bp) analysis. Twelve clonal subgroups (hsP‐I to hsP‐X and hsF‐I and hsF‐II) were designated on the hsp60 tree, inferred from representative sequences using the neighbor‐joining method. Some of the isolates showed unique subgroups depending on the source of isolates, including hsP‐I, hsF‐I, and hsF‐II from cooling tower water, and subgroups hsP‐VIII and hsP‐X from circulating hot water bath. These subgroups may be useful for epidemiological studies to chase or specify sources of infection in Korea and Japan.
