The type and clinical strains of two recently described coagulase-negative species of the genus Staphylococcus, Staphylococcus petrasii and Staphylococcus jettensis, were compared using dnaJ, tuf, gap, hsp60 and rpoB gene sequences, DNA-DNA hybridization, ribotyping, repetitive sequence-based PCR fingerprinting and extensive biochemical characterization. Based on the results, the species description of S. petrasii has been emended and S. jettensis should be reclassified as a novel subspecies within S. petrasii for which the name Staphylococcus petrasii subsp. jettensis subsp. nov. is proposed. The type strain is SEQ110(T) ( = LMG 26879(T) = CCUG 62657(T) = DSM 26618(T) = CCM 8494(T)).
