With the exception of indole and VP, read the reactions in a sequential fashion by comparing the colors of the media in the tube after incubation with those given in the color scheme on the cover of the coding interpretatoin and eventually with an uninoculated BBL Enterotube II which must be brought to room temperature first Figure 5.

Bergey s Manual of Determinative Bacteriology All of the unknowns will fall into the following groups in Bergey’s Manual of Determinative Bacteriology The pink book on the shelf in the laboratory. If no color change, or an orange color, is observed in the glucose compartment and growth is evident by color changes in other compartments, the organism is not a member of the family Enterobacteriaceae.

Urine Culture Melissa Schreiber, Presenter: Do not wait longer than 15 min before reading the results! For professional use only Do not use tubes if they show evidence of microbial contamination, discoloration, wax detachment from the respective media, drying, cracking or other signs of deterioration. This should be considered negative. Any reagent having a dark brown color should not be used.

Beige to light amber. System for the identification of Gram negative, oxidase positive bacteria. Allow reagent to contact the surface of the medium. Urease, an enzyme possessed by various microorganisms, hydrolyzes urea to ammonia causing the color of the indicator in the medium to shift from yellow acidic to red-purple alkaline. Some Providencia strains may produce a diffuse brown coloration in this medium, however, this should not be confused with true H 2S production as indicated by the presence of black color.

The position of hydrogen in the reactivity series Hydrogen, although not a metal, is included in the reactivity series because it, like metals, can be displaced from aqueous solution, only this time the. Make sure to use the right database [ 1 Oxidase negative nonfermenters, 2 Enterobacteriaceae method without VP, and 3 Entero-bacteriaceae method with VP]. After 18 to 24 hours of incubation, interpret all reactions. This kit is stable. Intefpretation 10 routine chemical tests performed on urine and list a.

Selective media allow certain types of organisms to grow, and inhibit the growth. Decarboxylation of ornithine, which results in the formation of the alkaline end product putrescine, is indicated by a change in the color of the indicator in the medium from pale yellow acidic to purple alkaline. Indicate each positive test result by circling the number appearing below the appropriate compartment on the Results Pad Figure 6.

H Biochemical characterization of Citrobacter freundii and Citrobacter diversus. Bacterial fermentation of dulcitol, which results in the formation of acidic end products, is indicated by a change in color of the indicator present in the medium from green alkaline to yellow or pale yellow acidic.
