If colonies of Gram-unfavorable rods matching the description in Desk four are found, commence with even further identification by transferring representative suspect colonies separately, by the use of an inoculating wire, to your butt-slant tube of Triple Sugar&#one hundred fifty;Iron&#one hundred fifty;Agar Medium by initially streaking the surface with the slant after which you can stabbing the wire effectively beneath the floor. Incubate. If evaluation discloses no proof of tubes obtaining alkaline (purple) slants and acid (yellow) butts (with or without concomitant blackening of your butt from hydrogen sulfide output), the specimen fulfills the necessities in the test for that absence of the genus Salmonella.
