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.
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]).
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.
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer, diabetes, cystic fibrosis, [1] severe burns, AIDS, [2] or people who are very ...
A frequent test done with LIA agar is the LIA slant. Here the LIA is solidified at an angle, then inoculated with bacteria by stabbing the agar to within 1/4 inch of the bottom of the tube and streaking the slant. The slant is then incubated at 35 °C for 18–24 hours. The results are scored as follows: esto esta mal

The generic name Pseudomonas created for these organisms was defined in rather vague terms by Walter Migula in 1894 and 1900 as a genus of Gram-negative, rod-shaped, and polar-flagellated bacteria with some sporulating species. [7] [8] The latter statement was later proved incorrect and was due to refractive granules of reserve materials. [9]
