Two Gram-negative, rod-shaped bacteria were isolated from agricultural soils inCórdoba province in central Argentina. Their 16S rRNA gene sequences demonstratedthat they belong to the genus Burkholderia, with Burkholderia zhejiangensis asmost closely related formally named species; this relationship was confirmedthrough comparative gyrB sequence analysis. Whole-cell fatty acid analysissupported their assignment to the genus Burkholderia. Burkholderia sp. strainYI23, for which a whole-genome sequence is available, represents the same taxon, as demonstrated by its highly similar 16S rRNA (100% similarity) and gyrB(99.1-99.7%) gene sequences. The results of DNA-DNA hybridization experiments andphysiological and biochemical characterization further substantiated thegenotypic and phenotypic distinctiveness of the Argentinian soil isolates, forwhich the name Burkholderia cordobensis sp. nov. is proposed, with strainMMP81(T) ( = LMG 27620(T) = CCUG 64368(T)) as the type strain.
