  2. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology .

  3. Laboratory-acquired infection - Wikipedia

    en.wikipedia.org/wiki/Laboratory-acquired_infection

    Prior to 1950, few reports were made on laboratory-acquired infections, due to the lower level of awareness concerning the problem. In 1951, a paper from Sulkin and Pike presented data on viral infections contracted in laboratories, which advised caution on handling viruses in laboratory environments and brought public awareness to the issue.

  4. 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 ...

  5. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing microbiologists to select appropriate tests to provide a definitive ...

  6. List of unsolved problems in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    What do all the unknown proteins do? Two decades since the first eukaryotes were sequenced, the "biological role" of around 20% of proteins are still unknown. [10] Many of these proteins are conserved across most eukaryotic species and some are conserved in bacteria, indicating a role fundamental for life. [10] [11] [12] Determinants of cell size.

  7. CAMP test - Wikipedia

    en.wikipedia.org/wiki/CAMP_test

    This is an example of a positive CAMP test indicated by the formation of dark arrowheads where the Strep group B (Streptococcus agalactiae) meets the Staphylococcus aureus (light-yellow/golden middle streak with surrounding dark hemolysis).

  8. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    Once a bacterium has been identified following microbiological culture, antibiotics are selected for susceptibility testing. [5] Susceptibility testing methods are based on exposing bacteria to antibiotics and observing the effect on the growth of the bacteria (phenotypic testing), or identifying specific genetic markers (genetic testing). [6]

  9. Microbiology - Wikipedia

    en.wikipedia.org/wiki/Microbiology

    Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
