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.
Veillonella are Gram-negative bacteria (Gram stain pink) anaerobic cocci, unlike most Bacillota, which are Gram-positive bacteria. [1] This bacterium is well known for its lactate fermenting abilities. It is a normal bacterium in the intestines and oral mucosa of mammals.
Cocci are usually round or spherical in shape. They can form clusters and are non-motile. [7] Examples include Staphylococcus aureus, Streptococcus pyogenes, and Neisseria gonorrhea. Staphylococcus aureus
Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae. Neisseria species are Gram-negative bacteria included among the Pseudomonadota, a large group of Gram-negative forms. Neisseria diplococci resemble coffee beans when viewed microscopically. [1]
A Gram stain of a urethral exudate showing typical intracellular Gram-negative diplococci, which is diagnostic for gonococcal urethritis [17]. Neisseria species are fastidious, Gram-negative cocci (though some species are rod-shaped and occur in pairs or short chains) that require nutrient supplementation to grow in laboratory cultures. [18]
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1] Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic ) membrane and an outer ...
Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae.It is named after the Swiss ophthalmologist Victor Morax.The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase-positive, and catalase-positive properties. [2]
Gram-negative cocci (mainly Veillonella spp.). The frequency of isolation of anaerobic bacterial strains varies in different infectious sites. [ 3 ] Mixed infections caused by numerous aerobic and anaerobic bacteria are often observed in clinical situations.
