aBacterial strains were identified in free-living amoebae, isolated by culture on nonnutrient agar.
bEstimated with Clustal W 63 available on the website of Pôle Bio-Informatique Lyonnais, Lyon, France (http://pbil.ibcp.fr/).
c16S rRNA of Chlamydophila pneumoniae strain N16 (GenBank accession number U68426).
dBerg17 endosymbiont was shown to have a similar rRNA signature from Bn9 endosymbiont (binding of the Bn9658 hybridization probe designed for in situ identification of Parachlamydia acanthamoebae); however, the 16S rRNA sequence of that strain is not available.
eDirect polymerase chain reaction amplification and sequencing from DNA extracted from the respiratory sample; no strain was isolated.
