Staphylococci spp. are a genus of gram positive cocci of 0.5 - 1 μm diameter. [citation needed] Staphylococcus pseudintermedius is a non-motile and non-spore forming, facultatively anaerobic bacterium. [citation needed] It appears primarily as grape-like clusters morphologically, but can also be seen as individual or paired cocci.
Staphylococcus epidermidis is a very hardy microorganism, consisting of nonmotile, Gram-positive cocci, arranged in grape-like clusters. It forms white, raised, cohesive colonies about 1–2 mm in diameter after overnight incubation, and is not hemolytic on blood agar. [5]
Staphylococcus species can be differentiated from other aerobic and facultative anaerobic, Gram-positive cocci by several simple tests. [15] Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts.
But, each type of skin infection caused by staph bacteria is different. A few common skin infections caused by staph bacteria are: Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin.
In either scenario, a high probability exists that the microbe will form a biofilm. These infections can remain localized or become systemic (i.e. bacteremia). The severity of infection varies depending on the type of catheter, frequency of manipulation, and virulence factors of the S. haemolyticus strain. Removal of the catheter is usually ...
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 harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour.
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 cornubiensis is a species of Gram-positive cocci in the Staphylococcus intermedius Group (SIG): [1] a group of genetically and phenotypically similar bacterial species that were previously identified as S. intermedius. [2] [3] The bacterium was first isolated from a human skin infection in Cornwall, United Kingdom. [1]
