LEGIONELLA bozemanii was first isolated from lung tissue by Bozeman in 1959. The isolate came from a healthy scuba diver in Florida with fatal bronchopneumonia and was termed WIGA.1 A second isolate, MI-15, was recovered in 1979 from lung tissue from a patient with lymphatic leukemia in whom a fulminant pneumonia developed after submersion in brackish swamp water.2 In both cases, the organism was recovered on charcoal yeast extract (CYE) by guinea pig inoculation. Testing of the patient's serum sample with indirect fluorescent antibody (FA) showed an increase in antibody titer against both the MI-15 and WIGA isolates. Genetic and antigenic studies subsequently showed that the two isolated belonged to the same species. The proposed species name was L bozemanii.3

In addition, the Centers for Disease Control (CDC), Atlanta, found serologic evidence of the association of L bozemanii in ten other cases of community-acquired pneumonia.4 Immunofluorescent
