If colonies of Gram-destructive rods matching the description in Table 4 are found, progress with additional identification by transferring consultant suspect colonies individually, by way of an inoculating wire, to the butt-slant tube of Triple Sugar&#one hundred fifty;Iron–Agar Medium by to start with streaking the surface area with the slant then stabbing the wire well beneath the floor. Incubate. If examination discloses no proof of tubes owning alkaline (crimson) slants and acid (yellow) butts (with or devoid of concomitant blackening in the butt from hydrogen sulfide creation), the specimen satisfies the necessities of the test for your absence on the genus Salmonella.
