Abstract |
We define two new species in the genus Staphylococcus that are phenotypically similar to and have near identical 16S rRNA sequences to S. aureus. However, compared to S. aureus and each other, S. argenteus sp. nov. (type strain MSHR1132T =DSM 28299T, =SSI 89.005T) and S. schweitzeri sp. nov. (type strain FSA084T =DSM 28300T, =SSI 89.004T) demonstrate: 1) at a whole genome level considerable phylogenetic distance, lack of admixture, average nucleotide identity < 95%, and inferred DNA-DNA hybridization <70%; 2) different profiles as determined by MALDI-TOF MS; 3) a non-pigmented phenotype for S. argenteus sp. nov.; 4) S. schweitzeri sp. nov. is not detected by standard nucA PCR; 5) distinct peptidoglycan types compared to S. aureus; 6) a separate ecological niche for S. schweitzeri sp. nov.; and 7) a distinct clinical disease profile for S. argenteus sp. nov. compared to S. aureus. |
