Prevalence: Prevalence in epidemiology is the proportion of a population found to have a condition (typically a disease or a risk factor such as smoking or seat-belt use). It is arrived at by comparing the number of people found to have the condition with the total number of people studied, and is usually expressed as a fraction, as a percentage or as the number of cases per 10,000 or 100,000 people.Venereal Disease Research Laboratory test: The Venereal Disease Research Laboratory test (VDRL) is a blood test for syphilis that was developed by the eponymous lab. The VDRL test is used to screen for syphilis (it has high sensitivity), whereas other, more specific tests are used to diagnose the disease.History of syphilis: The history of syphilis has been well studied, but the exact origin of syphilis is unknown. There are two primary hypotheses: one proposes that syphilis was carried to Europe from the Americas by the crew of Christopher Columbus, the other proposes that syphilis previously existed in Europe but went unrecognized.Latex fixation test: The latex agglutination method is used clinically in the identification and typing of many important microorganisms. These tests are based on and utilize the patient's antigen-antibody immune response.Iodopropynyl butylcarbamateAssay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Eva Engvall: Eva Engvall, born 1940, is one of the scientists who invented ELISA in 1971.Eva Engvall, The Scientist 1995, 9(18):8Immunoperoxidase: Immunoperoxidase is a type of immunostain used in molecular biology, medical research, and clinical diagnostics. In particular, immunoperoxidase reactions refer to a sub-class of immunohistochemical or immunocytochemical procedures in which the antibodies are visualized via a peroxidase-catalyzed reaction.Direct agglutination test: A direct agglutination test (DAT) is any test that uses whole organisms as a means of looking for serum antibodies. The abbreviation, DAT, is most frequently used for the serological test for visceral leishmaniasis.Clonal Selection Algorithm: In artificial immune systems, Clonal selection algorithms are a class of algorithms inspired by the clonal selection theory of acquired immunity that explains how B and T lymphocytes improve their response to antigens over time called affinity maturation. These algorithms focus on the Darwinian attributes of the theory where selection is inspired by the affinity of antigen-antibody interactions, reproduction is inspired by cell division, and variation is inspired by somatic hypermutation.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Replica plating: 350px|right|thumb|[[Negative selection (artificial selection)|Negative selection through replica plating to screen for ampicillin sensitive colonies]]Hemagglutination assay: The hemagglutination assay (or haemagglutination assay; HA) and the hemagglutination inhibition assay (HI) were developed in 1941–42 by American virologist George Hirst as methods for quantitating the relative concentration of viruses, bacteria, or antibodies.Thermal cyclerBioline Reagents: Bioline Reagents is a primary manufacturer and developerBioline: The PCR Company | Company Profile of a wide range of specialised molecular biology products for the life science industry and research markets.
