| bacterium | <microbiology> A tiny, unicellular, prokaryotic organism that reproduces by cell division and usually has a cell wall, can be shaped like a sphere, rod or spiral and can be found in virtually any enviroment. (09 Oct 1997) |

| Binn's bacterium | A type of the typhoid-paratyphoid subgroups of the nonlactose-fermenting bacteria. (05 Mar 2000) |
| blue-green bacterium | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nitrogen fixation occur at regular intervals. According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |
| Chauveau's bacterium | Former name for Clostridium chauvoei. (05 Mar 2000) |
| pyogenic bacterium | A bacterium that causes a pyogenic infection, such as the pyogenic cocci (staphylococci, streptococci, pneumococci, meningococci) and Haemophilus influenzae. (05 Mar 2000) |
| sulphate-reducing bacterium | <microbiology> A prokaryote which is able to reduce sulphate SO4 (as a terminal electron acceptor) using electrons donated from organic acids, fatty acids, alcohols or hydrogen (electron donors). (19 Jan 1998) |
| endoteric bacterium | A bacterium that forms an endotoxin. (05 Mar 2000) |
| exoteric bacterium | A bacterium that secretes an exotoxin. (05 Mar 2000) |
| lysogenic bacterium | A bacterium in the symbiotic condition in which its genome includes the genome (probacteriophage) of a temperate bacteriophage; in occasional instances the probacteriophage dissociates from the bacterial genome, develops into vegetative bacteriophage, and then matures, causing lysis of the respective host bacterium and release into the culture medium of infective temperate bacteriophage, formerly, a pseudolysogenic bacterial strain, i.e., a "carrier" strain of bacteriophage of low infectivity. (05 Mar 2000) |
| respiratory enteric orphan virus | A nonenveloped icosahedral virus whose genome consists of double stranded RNA, belonging to the family Reoviridae, frequently found in both the respiratory and enteric tract. Synonym: REO virus. (05 Mar 2000) |
| tablets, enteric-coated | Tablets coated with material that delays release of the medication until after they leave the stomach. (12 Dec 1998) |
| enteric | Relating to the intestine. (18 Nov 1997) |
| enteric bacteria | A large group of Gram negative rod-shaped bacteria characterised by a facultatively aerobic metabolism. Many of them are commonly found in the intestines of animals. (09 Oct 1997) |
| enteric-coated | A term designating a special coating applied to tablets or capsules which prevents release and absorption of their contents until they reach the intestines. (18 Nov 1997) |
| enteric coated tablet | An oral dosage form in which a tablet is coated with a material to prevent or minimise dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug (e.g., aspirin) or protects the drug (e.g., erythromycin) from partial degradation in the acidic environment of the stomach.
