Diplococci are pairs of cocci. Examples of gram-negative diplococci are Neisseria spp. and Moraxella catarrhalis. Examples of gram-positive diplococci are Streptococcus pneumoniae and Enterococcus spp. [10] [11] Presumably, diplococcus has been implicated in encephalitis lethargica. [12] The genus Neisseria belongs to the family Neisseriaceae.
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.
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 . [ 1 ]
The bacteria are nonmotile, oxidase-negative, catalase-positive, Gram-positive cocci, 1.1 to 1.6 μm in diameter, that occur singly, in pairs, and in irregular clusters.. The G+C content of the type strain is 33 mo
Staphylococcus schleiferi is a facultatively anaerobic, coagulase-variable, Gram-positive cocci organism. [1] It is nonmotile and nonspore-forming. [21] When cultured on 5% sheep blood agar, isolates of S. schleiferi form circular, opaque, non-pigmented colonies of approximately 0.8 to 1.0μm in diameter.
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.
Violet-stained gram-positive cocci and pink-stained gram-negative bacilli. In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.
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.
