Kerstersia similis sp. nov., isolated from human clinical samples.

Analysis of gyrB gene sequences, (GTG)(5)-primed PCR fingerprinting and biochemical characteristics determined in the Biolog GEN III microtest system were used to differentiate an unnamed Kerstersia species from Kerstersia gyiorum, the type and only named species in this genus. The inability to oxidize D-galacturonic and D-glucuronic acids and the ability to oxidize D-serine, along with gyrB gene sequence analysis and (GTG)(5)-PCR fingerprints, readily differentiated the unnamed taxon from the type species. Therefore, we propose to formally classify this unnamed taxon as Kerstersia similis sp. nov. with strain LMG 5890(T) (= CCUG 46999(T)), isolated from a leg wound in the USA in 1983, as the type strain.
