| Centres for Disease Control | The federal facility for disease eradication, epidemiology, and education headquartered in Atlanta, Georgia, which encompasses the Centre for Infectious Diseases, Centre for Environmental Health, Centre for Health Promotion and Education, Centre for Prevention Services, Centre for Professional Development and Training, and Centre for Occupational Safety and Health. Formerly named Centre for Disease Control (1970), Communicable Disease Centre (1946). (05 Mar 2000) |

| centres for disease control and prevention | See: CDC. (12 Dec 1998) |
| riot control agents, chemical | Chemical substances which are employed during a riot in order to control or disperse the rioting parties. (12 Dec 1998) |
| growth control | <cell biology> When applied to cells usually means control of growth of the population, i.e. Of the rate of division rather than of the size of an individual cell. (18 Nov 1997) |
| pest control | The reduction or regulation of the population of noxious, destructive, or dangerous insects or other animals. (12 Dec 1998) |
| pest control, biological | The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents. (12 Dec 1998) |
| rodent control | The reduction or regulation of the population of noxious, destructive, or dangerous rodents through chemical, biological, or other means. (12 Dec 1998) |
| weed control | <botany> Mechanical or chemical control of unwanted plants. Measures which have to be undertaken in a plant community to guarantee the growth of the desired vegetation. See: herbicide. (09 Oct 1997) |
| communicable disease control | Programs of surveillance designed to prevent the transmission of disease by any means from person to person or from animal to man. (12 Dec 1998) |
| mosquito control | The reduction or regulation of the population of mosquitoes through chemical, biological, or other means. (12 Dec 1998) |
| control | In research, control subjects or control procedures permit comparison with experimental results. The first controlled clinical research was probably done in 1875 by the British naval surgeon James Lind who, on board the HMS Salisbury, gave sailors with scurvy either oranges or lemons or cider or vinegar or nutmeg (or another treatment) and after just six days discovered that the citrus-consuming sailors had recovered from scury, until then the scourge of extended sea voyages, while the sailors who had been given the other treatments remained uncured. (12 Dec 1998) |
| control animal | In research, an animal submitted to the same conditions as the others used for the experiment, but with the crucial factor (such as the injection of antitoxin, the administration of a drug, etc.) omitted. See: control, control experiment. (05 Mar 2000) |
| control arm | The group of participants in a clinical trial who receive standard treatment or a placebo, against which those receiving the experimental treatment are compared. (09 Oct 1997) |
| control element | Generic term for a region of DNA, such as a promoter or enhancer adjacent to (or within) a gene that allows the regulation of gene expression by the binding of transcription factors. (18 Nov 1997) |
| control experiment | An experiment used to check another, to verify the result, or to demonstrate what would have occurred had the factor under study been omitted. See: control, control animal. (05 Mar 2000) |
