  3. Oxidase - Wikipedia

    en.wikipedia.org/wiki/Oxidase

    In microbiology, the oxidase test is used as a phenotypic characteristic for the identification of bacterial strains; it determines whether a given bacterium produces cytochrome oxidases (and therefore utilizes oxygen with an electron transfer chain). The test is used to determine whether a bacterium is an aerobe or anaerobe. However a ...

  4. NADPH oxidase - Wikipedia

    en.wikipedia.org/wiki/NADPH_oxidase

    NADPH oxidase (nicotinamide adenine dinucleotide phosphate oxidase) is a membrane-bound enzyme complex that faces the extracellular space. It can be found in the plasma membrane as well as in the membranes of phagosomes used by neutrophil white blood cells to engulf microorganisms.

  5. Diagnostic microbiology - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_Microbiology

    The catalase test tests whether a microbe produces the enzyme catalase, which catalyzes the breakdown of hydrogen peroxide. Smearing a colony sample onto a glass slide and adding a solution of hydrogen peroxide (3% H 2 O 2) will indicate whether the enzyme is present or not. Bubbling is a positive test while nothing happening is a negative ...

  6. Obligate aerobe - Wikipedia

    en.wikipedia.org/wiki/Obligate_aerobe

    They can be found evenly spread throughout the test tube. An obligate aerobe is an organism that requires oxygen to grow. [ 1 ] Through cellular respiration , these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy.

  7. Staphylococcus - Wikipedia

    en.wikipedia.org/wiki/Staphylococcus

    S. aureus is catalase-positive (meaning that it can produce the enzyme catalase) and able to convert hydrogen peroxide (H 2 O 2) to water and oxygen, which makes the catalase test useful to distinguish staphylococci from enterococci and streptococci. S. pseudintermedius inhabits and sometimes infects the skin of domestic dogs and cats. This ...

  8. Liver function tests - Wikipedia

    en.wikipedia.org/wiki/Liver_function_tests

    Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.

  9. Myeloperoxidase - Wikipedia

    en.wikipedia.org/wiki/Myeloperoxidase

    Myeloperoxidase (MPO) is a peroxidase enzyme that in humans is encoded by the MPO gene on chromosome 17. [5] MPO is most abundantly expressed in neutrophils (a subtype of white blood cells), and produces hypohalous acids to carry out their antimicrobial activity, including hypochlorous acid, the sodium salt of which is the chemical in bleach.
