  1. Escherichia coli ( / ˌɛʃəˈrɪkiə ˈkoʊlaɪ / ESH-ə-RIK-ee-ə KOH-ly) [1] [2] is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. [3] [4] Most E. coli strains are harmless, but some serotypes such as EPEC, and ETEC are ...

  4. Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef. [1] [2] Infection with this type of pathogenic ...

  5. Dec 31, 2022 · Abstract. 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 ...

  6. Aug 6, 2013 · Escherichia coli can grow and divide in a wide range of pressure (1–400 atm) and temperature (23–40°C). For T > 30°C, the doubling time of E. coli increases exponentially with pressure and exhibits a departure from exponential behavior at pressures between 250 and 400 atm for all the temperatures studied in our experiments.

  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 ...
