Use of partial 16S rRNA gene sequencing for identification of Legionella pneumophila and non-pneumophila Legionella spp

We examined 49 Legionella species, 26 L. pneumophila and 23 non-pneumophila Legionella spp., using partial 16S rRNA gene sequencing. This approach accurately identified all the L. pneumophila isolates, characterized all non-pneumophila Legionella isolates as such within this genus, and classified most (20/23; 87%) of the non-pneumophila Legionella isolates to the species level.
