If colonies of Gram-destructive rods matching the description in Table four are located, progress with additional identification by transferring consultant suspect colonies independently, through an inoculating wire, to the butt-slant tube of Triple Sugar&#a hundred and fifty;Iron–Agar Medium by 1st streaking the surface with the slant after which stabbing the wire properly beneath the surface. Incubate. If evaluation discloses no evidence of tubes having alkaline (red) slants and acid (yellow) butts (with or without having concomitant blackening in the butt from hydrogen sulfide generation), the specimen satisfies the necessities from the test for your absence of your genus Salmonella.
