| coliform bacilli | A common name for Escherichia coli that is used as an indicator of faecal contamination of water, measured in terms of coliform count. Occasionally used to refer to all lactose-fermenting enteric bacteria. (05 Mar 2000) |
|---|---|
| coliform bacteria | Bacteria whose presence in waste water is an indicator of pollution and of potentially dangerous contamination. (05 Dec 1998) |
| colimycin | <chemical> Cyclic polypeptide antibiotic from bacillus colistinus. It is composed of polymyxins e1 and e2 (or colistins a, b, and c) which act as detergents on cell membranes. Colistin is less toxic than polymyxin b, but otherwise similar; the methanesulfonate is used orally. Pharmacological action: antibiotics, peptide. Chemical name: Colistin (12 Dec 1998) |
| colinear | <molecular biology> A linear molecule having a sequence of units which corresponds to the sequence of units in another linear molecule. For example: the sequence of amino acids in a polypeptide corresponds to the sequence of nucleotide bases of the mRNA which was translated to make it. In bacteria the sequence of nucleotide bases in an mRNA molecule is colinear with the sequence of nucleotide bases in a DNA segment which was transcribed to make it (though this is not the case for eukaryotes, which have introns). (09 Oct 1997) |
| colinus | A genus of birds (family phasianidae) consisting of the bobwhites. (12 Dec 1998) |
| colipase | <protein> Protein cofactor for lipase. (18 Nov 1997) |
| colipases | Colipase I and II, consisting of 94-95 and 84-85 amino acid residues, respectively, have been isolated from porcine pancreas. Their role is to prevent the inhibitory effect of bile salts on the lipase-catalyzed intraduodenal hydrolysis of dietary long-chain triglycerides. (12 Dec 1998) |
| coliphage | <virology> A bacteriophage (a virus which infects bacteria) that specialises in colliforms (a type of bacteria which inhabits the bowels of larger organisms). (09 Oct 1997) |
| coliphages | Viruses whose host is escherichia coli. (12 Dec 1998) |
| coliplication | Reduction of the lumen of a dilated colon by making folds or tucks in its walls. Synonym: coliplication. Origin: colo-+ Mod. L. Plica, fold (05 Mar 2000) |
| colipuncture | Puncture of the colon with a trochar or scalpel to relieve distention. Synonym: colipuncture, colopuncture. Origin: colo-+ G. Kentesis, a puncture (05 Mar 2000) |
| colistimethate sodium | Pentasodium colistinmethanesulfonate;contains the pentasodium salt of the penta(methanesulfonic acid) derivative of colistin A as the major component, with a small proportion of the pentasodium salt of the same derivative of colistin B; an effective antibiotic against most Gram-negative bacilli (except Proteus), given intramuscularly. See: colistin sulfate, polymyxin. Synonym: cholistine sulphomethate sodium, colistin sulfomethate sodium. (05 Mar 2000) |

| colistinase | <enzyme> Serine alkaline protease from bacillus polymyxa var. Colistinus Registry number: EC 3.4.21.- Synonym: colistinase I, colistinase II (26 Jun 1999) |
