| calculated mean organism | A hypothetical organism whose characters are the means of both the positive and negative characters of the organism's which belong to the same taxon as the CMO, as opposed to the hypothetical mean. Organism. (05 Mar 2000) |

| cloning, organism | The formation of one or more genetically identical organisms derived by vegetative reproduction from a single cell. The source nuclear material can be embryo-derived, foetus-derived, or taken from an adult somatic cell. (12 Dec 1998) |
| pleuropneumonia like organism | Very tinymicroorganisms (usually spherical with a diameter of 0.3 to 0.8 micrometres, the smallest cells known) which are able to slip through most filters andare therefore often found as contaminating organisms in cultures, vaccines and other supposedly sterile preparations. Some types of mycoplasmas cause pneumonia. Mycoplasmal contamination is an important problem in biotechnology, but fortunately the microbes can usually be killed with antibiotics. (09 Oct 1997) |
| hypothetical mean organism | A hypothetical organism whose characters are the means of the positive characters of the organisms which belong to the same taxon as the HMO, as opposed to the calculated mean organism. (05 Mar 2000) |
| nontarget organism | An organism which is affected by an interaction (for example, a pesticide application) for which it was not the intended recipient. (09 Oct 1997) |
| defective organism | Mutant with a nutritional requirement not present in the wild type organism. Synonym: defective organism, deficiency mutant. (05 Mar 2000) |
| organism | <biology> Any individual living thing, whether animal or plant. (18 Nov 1997) |
| ectocommensal organism | An organism that benefits from living on the outer surface of another organism without harming the other organism. A type of commensalism. (09 Oct 1997) |
| transgenic organism | <molecular biology> Organisms that have integrated foreign DNA into their germ line as a result of the experimental introduction of DNA. Recombinant DNA techniques are commonly used to produce a transgenic organism. (13 Nov 1997) |
| enteric organism | A microorganism that lives in the intestines. (09 Oct 1997) |
| fastidious organism | A bacterial organism having complex nutritional requirements. (05 Mar 2000) |
| radical mastectomy, total | Breast cancer treatment involving removal of the breast, the pectoral (chest) muscles, lymph nodes (the glands ) in the armpit and associated skin and subcutaneous tissue. (12 Dec 1998) |
| parenteral nutrition, home total | The at-home administering of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously or by some other non-alimentary route. (12 Dec 1998) |
| parenteral nutrition, total | The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of tpn solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins. (12 Dec 1998) |
| reversal of organs, total | This condition (medically called situs inversus totalis) involves complete transposition (right to left reversal) of the thoracic and abdominal organs. The heart is not in its usual position in the left chest but is on the right. Specifically related to the heart, this is referred to as dextrocardia (literally, right-hearted). And the stomach, which is normally in the left upper abdomen, is on the right. In patients with situs inversus totalis, all of the chest and abdominal organs are reversed and appear in mirror image when examined or visualised by tests such as X-ray filming. Situs inversus totalis has been estimated to occur once in about 6-8,000 births. Situs inversus occurs in a rare abnormal condition that is present at birth (congenital) called kartagener's syndrome.
