| marine toxins | Toxic or poisonous substances elaborated by marine flora or fauna. They include also specific, characterised poisons or toxins for which there is no more specific heading, like those from poisonous fishes. Clupeotoxin, pahutoxin, prymnesin, scombrotoxin go here. (12 Dec 1998) |

| 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.
