  2. Oxidase test - Wikipedia

    en.wikipedia.org/wiki/Oxidase_test

    The oxidase test is used to determine whether an organism possesses the cytochrome c oxidase enzyme. The test is used as an aid for the differentiation of Neisseria, Moraxella, Campylobacter and Pasteurella species (oxidase positive). It is also used to differentiate pseudomonads from related species. [1]

    Before starting a test, one must confirm the cultured bacteria are Enterobacteriaceae, this is done by a quick oxidase test for cytochrome coxidase. Enterobacteriaceae are typically oxidase negative, meaning they either do not use oxygen as an electron acceptor in the electron transport chain , or they use a different cytochrome enzyme for ...

    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 ...

  5. Alcaligenes faecalis - Wikipedia

    en.wikipedia.org/wiki/Alcaligenes_faecalis

    A. faecalis is a Gram-negative bacterium which appears rod-shaped and motile under a microscope. It is positive by the oxidase test and catalase test, but negative by the nitrate reductase test. It is alpha-hemolytic and requires oxygen. A. faecalis can be grown at 37 °C, and forms colonies that lack pigmentation. [1]

  6. Streptococcus - Wikipedia

    en.wikipedia.org/wiki/Streptococcus

    Streptolysin O is an oxygen-sensitive cytotoxin, secreted by most group A Streptococcus (GAS), and interacts with cholesterol in the membrane of eukaryotic cells (mainly red and white blood cells, macrophages, and platelets), and usually results in beta-hemolysis under the surface of blood agar. Streptolysin S is an oxygen-stable cytotoxin also ...

  7. Elizabethkingia meningoseptica - Wikipedia

    en.wikipedia.org/wiki/Elizabethkingia_meningoseptica

    E. meningoseptica is positive by the catalase test, the oxidase test, and the indole test. It is negative by the urease test. In general, it is negative by the nitrate reductase test, although some strains are positive. [6] E. meningoseptica grows well on blood agar and chocolate agar. Colonies are very pale yellow and may not be easily evident ...

    Pseudomonas species also typically give a positive result to the oxidase test, the absence of gas formation from glucose, glucose is oxidised in oxidation/fermentation test using Hugh and Leifson O/F test, beta hemolytic (on blood agar), indole negative, methyl red negative, Voges–Proskauer test negative, and citrate positive.
