Thin paper discs containing an antibiotic have been placed on an agar plate growing bacteria. Bacteria are not able to grow around antibiotics to which they are sensitive. This is called "the zone of inhibition". Antibiotic sensitivity testing or antibiotic susceptibility testing is the measurement of the susceptibility of bacteria to antibiotics.
Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
Medical microbiology. A microbiologist examining cultures under a dissecting microscope. Medical microbiology, the large subset of microbiology that is applied to medicine, is a branch of medical science concerned with the prevention, diagnosis and treatment of infectious diseases. In addition, this field of science studies various clinical ...
Etest is a quantitative technique for determining the antibiotic sensitivity and minimum inhibitory concentration (in μg/mL) of some bacteria including Gram-negative and Gram-positive aerobic bacteria such as Enterobacteriaceae, [2] Pseudomonas, [2] [3] [4] Burkholderia, [2] [5] Staphylococcus, [6] and Enterococcus [7] species and fastidious bacteria, such as anaerobes, N. gonorrhoeae, S ...

In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible in vitro growth of bacteria or fungi. [1][2] MIC testing is performed in both diagnostic [1][2] and drug discovery laboratories. [3][4] The MIC is determined by preparing a dilution series of the chemical ...
Gold standard (test) In medicine and medical statistics, the gold standard, criterion standard, [1] or reference standard[2] is the diagnostic test or benchmark that is the best available under reasonable conditions. [3] It is the test against which new tests are compared to gauge their validity, and it is used to evaluate the efficacy of ...
Voges–Proskauer / ˈ f oʊ ɡ ə s ˈ p r ɒ s k aʊ. ər / or VP is a test used to detect acetoin in a bacterial broth culture. The test is performed by adding alpha-naphthol and potassium hydroxide to the Voges-Proskauer broth, which is a glucose-phosphate broth that has been inoculated with bacteria.
