What is the morphology of Escherichia coli?
Traditionally, the colony morphology of Escherichia coli is identified as either a rough or a smooth form. The two forms are readily distinguished, as the colonies of the former are rough, flat, and irregular and colonies of the latter are smooth, high, and circular.
What is Escherichia coli define its type and morphology?
Type and morphology E. coli is a Gram-negative, facultative anaerobe, nonsporulating coliform bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm3.
What is the arrangement and cell morphology of E. coli?
coli is gram-negative (-ve) rod-shaped bacteria. It is 1-3 x 0.4-0.7 µm in size and 0.6 to 0.7 µm in volume. It is arranged singly or in pairs. It is motile due to peritrichous flagella.
What is Escherichia coli characteristics?
CHARACTERISTICS: Enteropathogenic Escherichia coli (EPEC) are in the family Enterobacteriaceae 2. The bacteria are gram negative, rod shaped, non-spore forming, motile with peritrichous flagella or nonmotile, and grow on MacConkey agar (colonies are 2 to 3 mm in diameter and red or colorless) 5.
What is the size of Escherichia coli?

What is the size of E. coli?
The Size and Contents of an Average Gram-Negative Organism Escherichia coli is a typical gram-negative rod bacterium. Its dimensions are those of a cylinder 1.0-2.0 micrometers long, with radius about 0.5 micrometers.
What is the size of bacteriophage?
24-200 nm
Most phages range in size from 24-200 nm in length. All phages contain a head structure which can vary in size and shape. Some are icosahedral (20 sides) others are filamentous.
What is the length of E. coli DNA?
coli DNA is 1.36 mm, can you calculate the number of base pairs in E.
