|---|---|
| Treponema cuniculi | A species which causes spirochetosis in rabbits. (05 Mar 2000) |
| Treponema denticola | Cultivatable species that does not ferment carbohydrates and can be isolated from the oral cavity of humans. (05 Mar 2000) |
| Treponema genitalis | A nonpathogenic species found on the genitalia of humans. (05 Mar 2000) |
| Treponema hyodysenteriae | An enteropathogenic species that causes swine dysentery. (05 Mar 2000) |
| treponema-immobilizing antibody | Antibody, evoked during syphilitic infections, possessing specific affinity for Treponema pallidum, and which in the presence of complement immobilises the organism. Synonym: immobilizing antibody, treponemal antibody. (05 Mar 2000) |
| Treponema mucosum | A species found in pyorrhoea alveolaris; it possesses pyogenic properties. (05 Mar 2000) |
| Treponema pertenue | A species that causes yaws; patients with this disease give positive results in serologic screening tests for syphilis. (05 Mar 2000) |
| ammonia fixation | The utilization of ammonia (or ammonium ions) in the net synthesis of nitrogen-containing molecules; e.g., glutamine synthetase. Synonym: ammonia fixation. (05 Mar 2000) |
| bifoveal fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| binocular fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| carbon fixation | <plant biology> The process by which photosynthetic organisms such as plants turn inorganic carbon (usually carbon dioxide) into organic compounds (us. Carbohydrates). (09 Oct 1997) |
| mandibulomaxillary fixation | Fixation of fractures of the mandible or maxilla by applying elastic bands or stainless steel wire between the maxillary and mandibular arch bars or other types of splint. Synonym: mandibulomaxillary fixation, maxillomandibular fixation. (05 Mar 2000) |
| genes, nitrogen fixation | Regulatory and structural genes present in certain bacteria, algae and fungi that control the conversion of atmospheric nitrogen into biologically usable compounds; include nif structural genes (e.g., nifd, nifh) for nitrogenase and nitrate reductase as well as regulator genes nifa, nifb, ntra, ntrb, ntrc. Some are responsible for regulating transcription of genes involved in the assimilation of poor nitrogen sources in enteric bacteria. (12 Dec 1998) |
| genetic fixation | The increase of the frequency of a gene by genetic drift until no other allele is preserved in a specific finite population. (05 Mar 2000) |
