Bacterial cellular morphologies - Wikipedia
网页Structure b represents diplococcus bacteria. 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]

Diplococcus | bacteria | Britannica
网页Pairs of cocci are called diplococci; rows or chains of such cells are called streptococci; grapelike clusters of cells, staphylococci; packets of eight or more cells, sarcinae; and groups of four cells in a square arrangement, tetrads. These characteristic groupings occur as a result of variations in the reproduction process….
2.1: Sizes, Shapes, and Arrangements of Bacteria
网页2023年8月31日 — There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.
Meningococcal Disease (Neisseria meningitidis Infection)
网页2024年2月27日 — N meningitidis is an aerobic or facultative anaerobic, gram-negative diplococcus that exclusively infects humans (see Image. Diplococci). There are at least 12 serotypes based on unique capsular polysaccharides of N meningitidis, with serotypes A, B, C, W, X, and Y responsible for the majority of meningococcal infections. Serotypes A and C …
