If colonies of Gram-unfavorable rods matching the description in Desk four are identified, move forward with even further identification by transferring agent suspect colonies individually, by the use of an inoculating wire, to some butt-slant tube of Triple Sugar&#one hundred fifty;Iron&#a hundred and fifty;Agar Medium by to start with streaking the surface from the slant after which you can stabbing the wire very well beneath the surface area. Incubate. If examination discloses no evidence of tubes having alkaline (purple) slants and acid (yellow) butts (with or without the need of concomitant blackening of the butt from hydrogen sulfide production), the specimen fulfills the necessities with the test for your absence on the genus Salmonella.
