  2. Deinococcus radiodurans - Wikipedia

    en.wikipedia.org/wiki/Deinococcus_radiodurans

    Deinococcus radiodurans. Brooks & Murray, 1981. Look up Deinococcus or radiodurans in Wiktionary, the free dictionary. Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile.

  3. Disk diffusion test - Wikipedia

    en.wikipedia.org/wiki/Disk_diffusion_test

    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 ...

  4. Microbiology - Wikipedia

    en.wikipedia.org/wiki/Microbiology

    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 ...

  5. Minimum inhibitory concentration - Wikipedia

    en.wikipedia.org/wiki/Minimum_inhibitory...

    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 ...

  6. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    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.

  7. Etest - Wikipedia

    en.wikipedia.org/wiki/Etest

    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 ...

  8. Bacterial cellular morphologies - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cellular...

    Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea ). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...

  9. Proteus vulgaris - Wikipedia

    en.wikipedia.org/wiki/Proteus_vulgaris

    Proteus vulgaris is a rod-shaped, nitrate-reducing, indole -positive and catalase -positive, hydrogen sulfide -producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter. It is grouped with the Morganellaceae and is an opportunistic pathogen of humans.
