The strains were Gram-stain-positive, non-motile cocci, catalase-positive and coagulase-negative. Sequence analysis of the 16S rRNA gene, sodA, rpoB, dnaJ and hsp60 and phylogenetic characteristics revealed that the strains showed the closest relatedness to Staphylococcus microti CCM 4903T and Staphylococcus muscae DSM 7068T. The strains can be differentiated from S. microti by the absence of mannose fermentation and arginine arylamidase and from S. muscae by the absence of β-glucuronidase activity and production of alkaline phosphatase. The chosen type strain ARI 262T shared 20.1 and 31.9 % DNA relatedness with S. microti DSM 22147T and S. muscae CCM 4903T, respectively, by DNA–DNA hybridization. iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 0 were the most common fatty acids. Cell-wall structure analysis revealed the peptidoglycan type A3α l-Lys–Gly2–l-Ser–Gly (type A11.3). The presence of teichoic acid was determined by sequencing the N-acetyl-β-d-mannosaminyltransferase gene tarA, which is involved in biosynthesis of ribitol teichoic acid. Menaquinone 7 (MK-7) was the predominant respiratory quinone. The G+C content of ARI 262T was 38.8 mol%. The isolated strains represent a novel species of the genus Staphylococcus, for which we propose the name Staphylococcus rostri sp. nov. The type strain is ARI 262T (=DSM 21968T =CCUG 57266T) and strain ARI 602 (=DSM 21969 =CCUG 57267) is a reference strain.", }
