Abstract: Staphylococci constitute an important component of the human microbiome. Most of them are coagulase-negative species, whose importance in the pathogenesis of human infections has been widely recognized and is being documented on a regular basis. Until recently, the only well-known coagulase-positive staphylococcus species recognized as human pathogen was Staphylococcus aureus. Previously, the ability to produce coagulase was used as its basic diagnostic feature, because other coagulase-positive species were associated with animal hosts. Progress in the laboratory medicine, in which automatic or semi-automatic systems identify the staphylococci species, revealed a phenomenon of spreading of the coagulase positive staphylococci to new niches and hosts, as they are being isolated from human clinical materials with increasing frequency. As a result, many reaserchers and laboratories have turned their attention to the phenomenon, which caused an inflow of new data on these species. An increasingly expansive pathogenic potential of coagulase-positive staphylococci against humans has been documented. In the presented study, recent data on both S. aureus and species previously considered to be animal, i.e. S. intermedius, S. pseudintermedius, S. delphini, S. lutrae, S. schleiferi subsp. coagulans, S. hyicus as well as newly described species S. agnetis, were shown.
