title: The use of 16S ribosomal RNA analyses to investigate the phylogeny of the family Legionellaceae.
abstract: The 16S ribosomal RNA sequences of Legionella pneumophila, L. erythra, L. hackeliae, L. spiritensis, L. longbeachae, L. bozemanii (Fluoribacter bozemanae) and L. micdadei (Tatlockia micdadei) were determined using reverse transcriptase. The sequences were compared with published sequences for Gram-negative bacteria and phylogenetic trees were constructed. The data confirm previous work which showed that the family Legionellaceae forms a monophyletic subgroup within the gamma subdivision of the Proteobacteria. The data show that all of the legionellae studied are highly related (greater than 95%) on the basis of 16S rRNA sequences and do not support the division of the family Legionellaceae into three genera.
