If colonies matching The outline in Desk five are located, move forward with further identification by transferring the suspect colonies independently, by the use of an inoculating loop, to the area of Levine Eosin&#one hundred fifty;Methylene Blue Agar Medium, plated on petri dishes. If several colonies are to generally be transferred, divide the surface area of each plate into quadrants, Every of which may be seeded from the individual colony.

This information will not address one other balance necessity of ongoing efficacy during purchaser use and that is done by “in-use testing”, a very important matter for one more write-up.

Incubate. If examination discloses no proof of tubes possessing alkaline (pink) slants and acid (yellow) butts (with or devoid of concomitant blackening of your butt from hydrogen sulfide manufacturing), the specimen meets the necessities from the test for that absence from the genus Salmonella.
