Staphylococcus succinus is a Gram-positive coccoid bacterium belonging to the genus Staphylococcus.

This species was first described in 1998 and was isolated from 25- to 35-million-year-old Dominican amber.

Cells are Gram-positive, spherical (diameter 0.6–1.9 μm) and form characteristic rosettes with one central cell surrounded by two to five peripheral cells. Colonies after 2 days in tryptose soy agar at 25 °C are raised with an elevated centre (umbonate), glossy, opaque white, rough, and crenated, and measure 4–6 mm. Growth occurs between 25 and 40 °C, but not at 42 °C. Optimal growth occurs at 28 °C. The species grows more slowly at 40 °C. It does not grow in the anaerobic portion of thioglycollate shake medium.

The G+C content is 35 mol%. The species is PGR-positive, indoxyl-phosphate positive, Voges-Proskauer negative, phosphatase positive but is unable to reduce nitrate to nitrite. It is resistant to novobiocin. Acid and gas are produced from lactose, mannose and trehalose.

Principal membrane fatty acids are the saturated, odd-numbered, branched-chain fatty acids C13 iso, C13 anteiso, C15 iso, C15 anteiso, C17 iso, and C17 anteiso. In addition, the cell membranes contain lOMeC 18 (tuberculostearic acid).

Two subspecies are recognised:

This species has been isolated from cheese, sausages and the skin of healthy wild animals.

This species has been isolated from human clinical material, but its role in pathogenesis has yet to be clarified.
