  2. Colony hybridization - Wikipedia

    en.wikipedia.org/wiki/Colony_hybridization

    Colony hybridization is a method of selecting bacterial colonies with desired genes through a straightforward cloning and transfer process. [1] The genes of interest have been added to a bacterial plasmid previously through recombination , allowing genes from other organisms to be analyzed within a bacterial colony.

  3. Thioglycolate broth - Wikipedia

    en.wikipedia.org/wiki/Thioglycolate_broth

    They can be found evenly spread throughout the test tube. Thioglycolate broth is a multipurpose, enrichment, differential medium used primarily to determine the oxygen requirements of microorganisms. Sodium thioglycolate in the medium consumes oxygen and permits the growth of obligate anaerobes. [1]

  4. Bacteriology - Wikipedia

    en.wikipedia.org/wiki/Bacteriology

    Koch, a pioneer in medical microbiology, worked on cholera, anthrax and tuberculosis. In his research into tuberculosis Koch finally proved the germ theory, for which he received a Nobel Prize in 1905. [5] In Koch's postulates, he set out criteria to test if an organism is the cause of a disease, and these postulates are still used today.

  5. Diagnostic microbiology - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_Microbiology

    Diagnostic microbiology is the study of microbial identification. Since the discovery of the germ theory of disease , scientists have been finding ways to harvest specific organisms. Using methods such as differential media or genome sequencing , physicians and scientists can observe novel functions in organisms for more effective and accurate ...

  6. Colony-forming unit - Wikipedia

    en.wikipedia.org/wiki/Colony-forming_unit

    In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...

  7. Etest - Wikipedia

    en.wikipedia.org/wiki/Etest

    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 ...

  8. Inoculation loop - Wikipedia

    en.wikipedia.org/wiki/Inoculation_loop

    [1] [2] This process is called inoculation. The tool consists of a thin handle with a loop about 5 mm wide or smaller at the end. It was originally made of twisted metal wire (such as platinum, tungsten or nichrome), but disposable molded plastic versions are now common. The size of the loop determines the volume of liquid an inoculation loop ...

  9. IMViC - Wikipedia

    en.wikipedia.org/wiki/IMViC

    The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". These tests are useful in distinguishing members of ...
