Ralstonia respiraculi sp nov., isolated from the respiratory tract of cystic fibrosis patients

Five isolates recovered from the respiratory tract of cystic fibrosis patients were included in a polyphasic taxonomic study that employed 16S rDNA sequence analysis, cellular protein and fatty acid analysis and biochemical characterization. Four isolates were classified as a novel Ralstonia species, for which the name Ralstonia respiraculi sp. nov. is proposed; the other isolate was phylogenetically closely related to R. respiraculi, but is likely to represent another novel Ralstonia species. The type strain of R. respiraculi is AU3313(T) ( LMG 21510(T)= CCUG 46809(T)).
