The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture -based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the ...
e. Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) ' life ' and -λογία ( -logía) 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells). [ 1][ 2] Microbiology encompasses numerous sub ...
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 ...
Microbial genetics. (Redirected from Microbial Genetics) Microbial genetics is a subject area within microbiology and genetic engineering. Microbial genetics studies microorganisms for different purposes. The microorganisms that are observed are bacteria and archaea. Some fungi and protozoa are also subjects used to study in this field.
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. [ 1] Because of the similarity of thinking and ...
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.
Etest is a pre-prepared non-porous plastic reagent strip with a predefined gradient of antibiotic, covering a continuous concentration range. It is applied to the surface of an agar plate inoculated with the test strain, where there is release of the antimicrobial gradient from the plastic carrier to the agar to form a stable and continuous ...
