It is one of the most frequent “hospital-borne” microbes that causes infections that are often antibiotic resistant.
As the name indicates, Staphylococcus remain in a “bunch of grapes” like morphology with individual coccus shaped bacteria clumped together (Sthaphylo-). It forms golden or yellow colonies on nutrient agar medium hence, the epithet “aureus’, (derived from Aurum= gold).
Since Staphylococcus are Gram-positive, they stain purple with Gram staining procedure. That indicates that they have a thick cell wall with abundant peptidoglycan and the outer membrane is absent. All other structural features of Staphylococcus are that of a typical prokaryotic cell. They don’t have a defined nucleus, they don’t possess membrane-bound organelles, the ribosomes are 70s abundant with 16SrRNA and they lack histones.
