If colonies of Gram-damaging rods matching the description in Table four are discovered, carry on with further identification by transferring agent suspect colonies independently, by means of an inoculating wire, to your butt-slant tube of Triple Sugar&#one hundred fifty;Iron&#one hundred fifty;Agar Medium by first streaking the floor with the slant and afterwards stabbing the wire well beneath the surface. Incubate. If evaluation discloses no proof of tubes owning alkaline (purple) slants and acid (yellow) butts (with or with no concomitant blackening of your butt from hydrogen sulfide manufacturing), the specimen meets the requirements on the test for the absence with the genus Salmonella.
