• Popis: A series of seven gram-positive, catalase positive cocci isolated from human clinical material and presumptively identified as Macrococcus sp. was investigated in the present study by a polyphasic approach. Phylogenetic position of the isolates was determined by 16S rDNA sequence analysis and hsp60 gene sequencing and harboured analysed strains as two separated clusters within the genus Macrococcus. Further phenotypic and genotypic analyses using extended biotyping, whole-cell protein profiling, automated ribotyping, pulsed field gel electrophoresis and rep-PCR fingerprinting confirmed separation of the investigated strains into two groups which were clearly separated from the validly recognised species of the genus Macrococcus. Based on these results two novel macrococci, Macrococcus petrasi sp. nov. (type strain CCM 7927T) originating from human clinical material and Macrococcus epidermidis sp. nov. (type strain CCM 7099T) inhabiting human skin are proposed.
