If colonies of Gram-negative rods matching the description in Table four are observed, move forward with further identification by transferring representative suspect colonies separately, by the use of an inoculating wire, to the butt-slant tube of Triple Sugar&#one hundred fifty;Iron–Agar Medium by very first streaking the surface area on the slant after which stabbing the wire effectively beneath the area. Incubate. If assessment discloses no evidence of tubes obtaining alkaline (purple) slants and acid (yellow) butts (with or without the need of concomitant blackening of the butt from hydrogen sulfide production), the specimen meets the requirements from the test for the absence from the genus Salmonella.
