Incubate. If evaluation discloses no proof of tubes getting alkaline (pink) slants and acid (yellow) butts (with or devoid of concomitant blackening in the butt from hydrogen sulfide production), the specimen satisfies the requirements of the test to the absence in the genus Salmonella.

. These testing methods have many various uses in numerous laboratories, that are as follows:

Buffer Resolution and Media Culture media could be organized as follows, or dehydrated society media can be used presented that, when reconstituted as directed by the company or distributor, they have identical substances and/or produce media comparable to These attained from the formulation offered herein.
