Analysis of partial gyrB gene sequences revealed six taxa in a group of 17 Burkholderia glathei-like isolates which were further examined by (GTG)(5)-PCR fingerprinting, 16S rRNA gene sequence analysis, DNA-DNA hybridizations, determination of the DNA G+C content, whole-cell fatty acid analysis and an analysis of cell and colony morphology and more than 180 biochemical characteristics. The results demonstrated that one taxon consisting of three human clinical isolates represented Burkholderia zhejiangensis, a recently described methyl-parathion-degrading bacterium isolated from a wastewater-treatment system in China. The remaining taxa represented five novel species isolated from soil or rhizosphere soil samples, and could be distinguished by both genotypic and phenotypic characteristics. We therefore propose to formally classify these bacteria as Burkholderia humi sp. nov. (type strain, LMG 22934(T)=CCUG 63059(T)), Burkholderia choica sp. nov. (type strain, LMG 22940(T)=CCUG 63063(T)), Burkholderia telluris sp. nov. (type strain, LMG 22936(T)=CCUG 63060(T)), Burkholderia udeis sp. nov. (type strain, LMG 27134(T)=CCUG 63061(T)) and Burkholderia terrestris sp. nov. (type strain, LMG 22937(T)=CCUG 63062(T)).
