Species of Staphylococcus have no regular plane of division. They form grape-like structures. [9] The various gram-positive cocci differ physiologically and by habitat. Micrococcus spp. are obligate aerobes that inhabit human skin. Staphylococcus spp. also inhabit human skin, but they are facultative anaerobes. They ferment sugars, producing ...

Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope , they appear spherical ( cocci ), and form in grape -like clusters.
In other Gram-positive bacteria, such as Staphylococcus aureus, the walls are resistant to the action of lysozymes. [4] They have O-acetyl groups on carbon-6 of some muramic acid residues. The matrix substances in the walls of Gram-positive bacteria may be polysaccharides or teichoic acids. The latter are very widespread, but have been found ...
Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters. It occurs very commonly as a generally harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour .
Staphylococcus on a catheter. S. haemolyticus can colonize central venous catheters and cause serious medical complications. Colonization occurs when S. haemolyticus migrates from the skin, along the external surface of the device, or from the hub, due to manipulation by health care workers. In either scenario, a high probability exists that ...
Staphylococcus schleiferi is a Gram-positive, cocci-shaped bacterium of the family Staphylococcaceae. [1] It is facultatively anaerobic, coagulase-variable, and can be readily cultured on blood agar where the bacterium tends to form opaque, non-pigmented colonies and beta (β) hemolysis. [2]
Staphylococcus xylosus is a species of bacteria belonging to the genus Staphylococcus. It is a Gram-positive bacterium that forms clusters of cells. Like most staphylococcal species, it is coagulase -negative and exists as a commensal on the skin of humans and animals and in the environment.
