    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 μm 3.

    Dec 31, 2022 · Escherichia coli have served as important model organisms for over a century—used to elucidate key aspects of genetics, evolution, molecular biology, and pathogenesis. However, defining which strains actually belong to this species is erratic and unstable due to shifts in the characters and criteria used to distinguish bacterial species.

    Jan 1, 2008 · E. coli is Gram-negative and its envelope has three layers: cytoplasmic membrane, peptidoglycan, and outer membrane. The peptidoglycan is rigid determining the rod shape. To a good approximation, the E. coli cell has hemispherical caps and a cylindrical section in between.

    The discussion of bacterial morphology has been dominated by questions about how a cell manages to create a rod shape, which, of course, is but one example of the more general question of how a cell constructs any shape. The expectation is that by answering this (deceptively) simple question we may acquire knowledge that will point us to a ...

    Historically, bacteriologists have relied heavily on biochemical and structural phenotypes for bacterial taxonomic classification. However, advances in comparative genomics have led to greater insights into the remarkable genetic diversity within the microbial world, and even within well-accepted species such as Escherichia coli. The extraordinary genetic diversity in E. coli recapitulates the ...
