  4. Aug 2, 2022 · However, given the vast diversity among bacteria and even among E. coli strains, it was by many fortuitous events that E. coli rose to the top as an experimental model. Here, we share how serendipity and its own biology selected E. coli as the flagship bacterium of molecular biology.

  5. Dec 21, 2020 · Escherichia coli (or E. coli) is a Gram-negative versatile bacterium, easily found and amenable to natural and random genetic alteration. There is a vast collection of sequenced E. coli genomes which exhibit different sizes and genomic diversity among commensal and pathogens, indicating a great assortment within the same bacterial species. They ...

  6. 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.

  7. Aug 21, 2020 · The genome of E. coli strains (excluding Shigella) varies from 4.2 to 6.0 Mbp, which corresponds to 3,900–5,800 genes, respectively 32, 33, 34. This variability is the result of frequent ...
