Staphylococcus (from the Greek: ÏÏÎ±ÏÏÎ»Î®, staphylÄ, grape and ÎºÏÎºÎºÎ¿Ï, kÃ³kkos, granule) is a genus of Gram-positive bacteria. Under the microscope, they appear round (cocci), and form in grape-like clusters. The Staphylococcus genus includes at least 40 species. Of these, nine have two subspecies, one has three subspecies, and one has four subspecies. Most are harmless and reside normally on the skin and mucous membranes of humans and other organisms. Found worldwide, they are a small component of soil microbial flora.
