If colonies of Gram-unfavorable rods matching the description in Desk 4 are found, progress with even more identification by transferring agent suspect colonies separately, through an inoculating wire, into a butt-slant tube of Triple Sugar–Iron&#one hundred fifty;Agar Medium by 1st streaking the surface area of the slant and then stabbing the wire nicely beneath the floor. Incubate.
