Staphylococcus argenteus are gram-positive cocci from the genus Staphylococcus which have been isolated from blood culture of a 55-year-old Indigenous Australian female in 2006 in Darwin, Northern Territory, Australia. The species is close related to S. aureus and the differentiation is challenging. While it is hard to differentiate between S. aureus and S. argenteus, it can be done via multilocus sequence typing (MSLT). S. argenteus can cause infections in the blood stream, skin/soft tissue, bones and joints. The species has also been identified in cases of food poisoning. Staphylococcus argenteus is cytotoxic to human cells due to high expression of alpha-hemolysin.
