  2. Proteus mirabilis - Wikipedia

    en.wikipedia.org/wiki/Proteus_mirabilis

    Proteus mirabilis appears as Gram-negative rods after Gram staining under bright-field microscopy with 1000 times magnification. Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It shows swarming motility and urease activity. P. mirabilis causes 90% of all Proteus infections in humans.

  3. XLD agar - Wikipedia

    en.wikipedia.org/wiki/XLD_agar

    Xylose lysine deoxycholate agar (XLD agar) is a selective growth medium used in the isolation of Salmonella and Shigella species from clinical samples and from food. [ 1 ] [ 2 ] The agar was developed by Welton Taylor in 1965. [ 3 ]

  4. Proteus (bacterium) - Wikipedia

    en.wikipedia.org/wiki/Proteus_(bacterium)

    The term Proteus signifies changeability of form, as personified in the Homeric poems in Proteus, "the old man of the sea", who tends the sealflocks of Poseidon and has the gift of endless transformation. The first use of the term “Proteus” in bacteriological nomenclature was made by Hauser (1885), who described under this term three types ...

  5. Microbial art - Wikipedia

    en.wikipedia.org/wiki/Microbial_art

    Agar plates are used as a canvas, while pigmented or fluorescent bacteria and yeasts represent paint. In order to preserve a piece of microbial art after a sufficient incubation, the microbe culture is sealed with epoxy. [2] Microbe species can be artistically chosen for their natural colours to form a palette.

  6. Swarming motility - Wikipedia

    en.wikipedia.org/wiki/Swarming_motility

    One particular feature of this type of motility is the formation of dendritic fractal-like patterns formed by migrating swarms moving away from an initial location. Although the majority of species can produce tendrils when swarming, some species like Proteus mirabilis do form concentric circles motif instead of dendritic patterns. [19]

  7. XLT agar - Wikipedia

    en.wikipedia.org/wiki/XLT_agar

    XLT Agar (Xylose Lysine Tergitol-4) is a selective culture medium for the isolation and identification of salmonellae from food and environmental samples. It is similar to XLD agar ; however, the agar is supplemented with the surfactant, Tergitol 4 , which causes inhibition of Proteus spp. and other non-Salmonellae. [ 1 ]

  8. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    Among these are Pseudomonas aeruginosa, which has a grape-like scent; Staphylococcus aureus, which is said to smell like old socks; and Proteus mirabilis, whose scent is alternately described as putrid [1]: 168 or like chocolate cake. [7]: 124 Other distinctive features of colonial morphology include motility and the production of pigments.

  9. Agar plate - Wikipedia

    en.wikipedia.org/wiki/Agar_plate

    A third technique is using sterile glass beads to plate out cells. In this technique, cells are grown in a liquid culture, in which a small volume is pipetted on the agar plate and then spread out with the beads. Replica plating is another technique used to plate out cells on agar plates. These four techniques are the most common, but others ...
