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.
A slant is prepared by adding the heated agar to a test tube and allowing it to solidify at a slanted angle. To transfer cells from a sample to the agar, a sterilized needle is used to select a distinct colony from the sample and to streak across the agar surface, as is done on an agar plate.

Cetrimide also enhances the production of Pseudomonas pigments such as pyocyanin and pyoverdine, which show a characteristic blue-green and yellow-green colour, respectively. [ 3 ] [ 4 ] Cetrimide agar is widely used in the examination of cosmetics, pharmaceuticals and clinical specimens to test for the presence of Pseudomonas aeruginosa .
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

Fauci stated, "New York City, in March and April 1947, vaccinated 6,350,000 people; 5 million of which they did in two weeks. I was a six-year-old boy who was one of those who got vaccinated. So if New York City can do 5 million in two weeks, the United States could do a million a day. We can do it." [22]
