Staphylococcus auricularis

Staphylococcus auricularis is a Gram-positive member of the bacterial genus Staphylococcus consisting of pairs or tetrads of cocci. This species was originally isolated from the exterior of a human ear and is weakly hemolytic. Because it commonly exists on human skin, it may be able to cause opportunistic infections or sepsis, although this is very rare.
