| Escherichia coli | <bacteria> The archetypal bacterium for biochemists, used very extensively in experimental work. A rod shaped gram-negative bacillus (0.5 x 3-5 m) abundant in the large intestine (colon) of mammals. Abbreviation: E. Coli (18 Nov 1997) |

| escherichia coli o157 | A verocytotoxin-producing serogroup belonging to the o subfamily of escherichia coli which has been shown to cause severe food-borne disease. Recently, a strain from this serogroup, serotype h7 which produces shiga-like toxins, has been linked to human disease outbreaks resulting from contamination of foods from bovine origin. This serogroup causes haemorrhagic and haemolytic uraemic syndrome and predominantly haemorrhagic diarrhoea and gastroenteritis in children. (12 Dec 1998) |

| Escherichia coli RNase I | <enzyme> An enzyme endonucleolytically cleaving RNA to 3'-nucleotides with 2',3'-cyclic nucleotides as intermediates. Synonym: Escherichia coli RNase I, microbial RNase II, plant RNase, RNase N2. (05 Mar 2000) |
| Escherichia freundii | Former name for Citrobacter freundii. (05 Mar 2000) |
| eschscholtzia | <botany> A genus of papaveraceous plants, found in California and upon the west coast of North America, some species of which produce beautiful yellow, orange, rose-coloured, or white flowers; the California poppy. Origin: NL. Named after Dr. Eschscholtz, a German botanist. Source: Websters Dictionary (01 Mar 1998) |
| eschynite | <chemical> A rare mineral, containing chiefly niobium, titanium, thorium, and cerium. It was so called by Berzelius on account of the inability of chemical science, at the time of its discovery, to separate some of its constituents. Origin: Gr. Shame.

| escin | <chemical> Aescigenin-(2-methyl-3-acetoxybutyrate)-(2-xylosido 4-glucosidoglucuronoside). Saponin occurring in the seed of the horse chestnut tree. Inhibits oedema formation and decreases vascular fragility. Synonym: feparil; reparil; aescusan. Chemical name: Escin (12 Dec 1998) |
| escorcin | A brown powder derived from esculetin, a substance derived from esculin; used for the detection of defects in the cornea and conjunctiva, which it marks by a red colouration. (05 Mar 2000) |
