E. coli is the most widely studied prokaryotic model organism, and an important species in the fields of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA. Under favourable conditions, it takes as little as 20 minutes to reproduce.

The average diameter of spherical bacteria is 0.5-2.0 µm. For rod-shaped or filamentous bacteria, length is 1-10 µm and diameter is 0.25-1 .0 µm. 1. E. coli , a bacillus of about average size is 1.1 to 1.5 µm wide by 2.0 to 6.0 µm long. 2. Spirochaetes occasionally reach 500 µm in length and the cyanobacterium 3. Oscillatoria is about 7 µm in diame...
The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. 1. Cocci(or coccus for a single cell) are round cells, sometimes slightly flattened when they are adjacent to one another. 2. Bacilli(or bacillus for a single cell) are rod-shaped bacteria. 3....
Cocci bacteria can exist singly, in pairs (as diplococci ), in groups of four (as tetrads ), in chains (as streptococci ), in clusters (as stapylococci ), or in cubes consisting of eight cells (as sarcinae). Cocci may be oval, elongated, or flattened on one side. Cocci may remain attached after cell division. These group characteristics are often u...
The cocci are arranged in pairs. Examples: Streptococcus pneumoniae, Moraxella catarrhalis, Neisseria gonorrhoeae, etc.
The cocci are arranged in chains, as the cells divide in one plane. Examples: Streptococcus pyogenes, Streptococcus agalactiae
The cocci are arranged in packets of four cells, as the cells divide in two plains. Examples: Aerococcus, Pediococcus and Tetragenococcus
The cocci are arranged in a cuboidal manner, as the cells are formed by regular cell divisions in three planes. Cocci that divide in three planes and remain in groups cube like groups of eight. Examples: Sarcina ventriculi, Sarcina ureae, etc.
The cocci are arranged in grape-like clusters formed by irregular cell divisions in three plains. Examples: Staphylococcus aureus
Spirilla (or spirillum for a single cell) are curved bacteria which can range from a gently curved shape to a corkscrew-like spiral. Many spirilla are rigid and capable of movement. A special group of spirilla known as spirochetes are long, slender, and flexible.
They are comma-shaped bacteria with less than one complete turn or twist in the cell. Example: Vibrio cholerae
Morphology: Rod. Arrangement: Strep aka chain. Negative Staining: Transparent but violet in the environment (bacteria only use in negative staining) Simple Staining: N/A. Study with Quizlet and memorize flashcards containing terms like Arrangement - you are correct.
Morphology and Staining of Escherichia Coli: E. coli is Gram-negative straight rod, 1-3 µ x 0.4-0.7 µ, arranged singly or in pairs (Fig. 28.1). It is motile by peritrichous flagellae, though some strains are non-motile.
