If colonies matching The outline in Table five are found, continue with further more identification by transferring the suspect colonies individually, by means of an inoculating loop, to the surface area of Levine Eosin&#a hundred and fifty;Methylene Blue Agar Medium, plated on petri dishes. If several colonies are for being transferred, divide the surface area of each and every plate into quadrants, Each and every of which can be seeded from the individual colony.
