  2. TSI slant - Wikipedia

    en.wikipedia.org/wiki/TSI_slant

    The TSI slant is a test tube that contains agar, a pH-sensitive dye , 1% lactose, 1% sucrose, 0.1% glucose, [2] and sodium thiosulfate and ferrous sulfate or ferrous ammonium sulfate. All of these ingredients are mixed together, heated to sterility, and allowed to solidify in the test tube at a slanted angle.

  3. Shigella dysenteriae - Wikipedia

    en.wikipedia.org/wiki/Shigella_dysenteriae

    Inoculation of a TSI slant shows an alkaline slant and acidic, but with no gas, or H 2 S production. Following incubation on SIM, the culture appears nonmotile with no H 2 S production. Addition of Kovac's reagent to the SIM tube following growth typically indicates no indole formation (serotypes 2, 7, and 8 produce indole [5]).

    When inoculated to a triple sugar iron slant, they react as follows: K/A, gas -, and H 2 S -. Indole reactions are mixed, positive and negative, with the exception of S. sonnei , which is always indole negative.

    Erysipelothrix rhusiopathiae is a Gram-positive, catalase-negative, rod-shaped, non-spore-forming, nonacid-fast, nonmotile bacterium.Distributed worldwide, E. rhusiopathiae is primarily considered an animal pathogen, causing the disease known as erysipelas that may affect a wide range of animals.

  6. Pseudomonas aeruginosa - Wikipedia

    en.wikipedia.org/wiki/Pseudomonas_aeruginosa

    A TSI slant is often used to distinguish nonfermenting Pseudomonas species from enteric pathogens in faecal specimens. [citation needed] When P. aeruginosa is isolated from a normally sterile site (blood, bone, deep collections), it is generally considered dangerous, and almost always requires treatment.
