If colonies of Gram-damaging rods matching The outline in Table four are observed, carry on with additional identification by transferring consultant suspect colonies individually, by means of an inoculating wire, to a butt-slant tube of Triple Sugar–Iron–Agar Medium by to start with streaking the surface area from the slant after which stabbing the wire effectively beneath the surface area. Incubate. If examination discloses no proof of tubes getting alkaline (red) slants and acid (yellow) butts (with or with out concomitant blackening with the butt from hydrogen sulfide creation), the specimen meets the necessities of your test for the absence in the genus Salmonella.
