| transmissible murine colonic hyperplasia | A disease of young mice caused by the bacterium Citrobacter freundii and characterised by diarrhoea and mucosal hyperplasia of the descending colon. (05 Mar 2000) |
|---|---|
| transmissible plasmid | Self-transmissible plasmid, a plasmid which encodes all the functions needed for its own intercellular transmission by conjugation. (09 Oct 1997) |
| transmissible turkey enteritis virus | A coronavirus causing bluecomb disease of turkeys. Synonym: bluecomb virus. (05 Mar 2000) |
| transmissible venereal tumour | A rapidly growing, soft, easily bleeding, infectious, connective tissue tumour occurring in the vagina of the female dog and on the penis and sheath of the male; ordinarily transmitted by coitus. Synonym: transmissible venereal tumour. (05 Mar 2000) |
| transmission | 1. <microbiology, physiology> A passage or transfer, as of a disease from one individual to another or of neutral impulses from one neuron to another. 2. <genetics> The communication of inheritable qualities from parent to offspring (18 Nov 1997) |
| transmission breakpoint | <epidemiology> A critical average worm burden below which the mating frequency is too low to maintain a dioecious parasite species. (05 Dec 1998) |
| transmission electron microscopy | <technique> Those forms of electron microscopy in which electrons are transmitted through the object to be imaged, suffering energy loss by diffraction and to a small extent by absorption. Acronym: TEM (18 Nov 1997) |
| transmission microscope | <instrument, optics> A microscope in which the image-forming rays pass through (are transmitted by) the specimen being observed. Refers to both light and electron microscopes. (05 Aug 1998) |
| transmission threshold | <epidemiology> Occurs for a parasite when the basic reproductive rate Ro is equal to 1. Below this threshold level the disease is unable to maintain itself within the host population. Typically, for directly transmitted parasites there is a transmission threshold for the host population size. (05 Dec 1998) |
| transmit | 1. To cause to pass over or through; to communicate by sending; to send from one person or place to another; to pass on or down as by inheritance; as, to transmit a memorial; to transmit dispatches; to transmit money, or bills of exchange, from one country to another. "The ancientest fathers must be next removed, as Clement of Alexandria, and that Eusebian book of evangelic preparation, transmitting our ears through a hoard of heathenish obscenities to receive the gospel." (Milton) "The scepter of that kingdom continued to be transmitted in the dynasty of Castile." (Prescott) 2. To suffer to pass through; as, glass transmits light; metals transmit, or conduct, electricity. Origin: L. Transmittere, transmissum; trans across, over + mittere to send: cf. F. Transmettre. See Missile. Source: Websters Dictionary (01 Mar 1998) |
| transmittance | <radiobiology> Ratio of the radiant power transmitted by an object to the incident radiant power. See: reflectivity. (09 Oct 1997) |
| transmitted light | <microscopy> The usual method for illuminating transparent microscopic specimens. The light is concentrated on the specimen by the substage condenser. Objects appear in outline (refraction images) or coloured on a bright field (colour images). (05 Aug 1998) |
| transmitter | One who, or that which, transmits; specifically, that portion of a telegraphic or telephonic instrument by means of which a message is sent; opposed to receiver. Source: Websters Dictionary (01 Mar 1998) |
| transmural | Through any wall, as of the body or of a cyst or any hollow structure. Origin: trans-+ L. Murus, wall (05 Mar 2000) |
| transmural myocardial infarction | Infarction that involves the whole thickness of the heart muscle from endocardium to epicardium. Synonym: through-and-through myocardial infarction. (05 Mar 2000) |
