If colonies matching the description in Table five are found, continue with further more identification by transferring the suspect colonies individually, by the use of an inoculating loop, for the surface of Levine Eosin&#one hundred fifty;Methylene Blue Agar Medium, plated on petri dishes. If a lot of colonies are to get transferred, divide the floor of every plate into quadrants, Every of which can be seeded from a different colony.

For a fluid specimen in aerosol form, chill the here container within an Alcoholic beverages-dry ice combination for about one hour, Lower open up the container, make it possible for it to achieve area temperature, allow the propellant to flee, or warm to push off the propellant if possible, and transfer the amount of test material needed with the procedures laid out in one of many two preceding paragraphs, as ideal.

Ensure any suspect colonial progress on a number of in the media as Pseudomonas aeruginosa through the oxidase test. On the colonial development position or transfer colonies to strips or disks of filter paper that Formerly has long been impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there is absolutely no growth of the pink color, transforming to purple, the specimen meets the requirements of your test for that absence of Pseudomonas aeruginosa.
