Test Kit, 60 Tests Microwell Format Gram Negative A Identification Microbial Identification

Features

• The Microgen Gram Negative ID system employs 12 (GN A) standardized biochemical substrates in microwells to identify the family Enterobacteriaceae and other non-fastidious gram negative bacilli (oxidase negative and positive) within 18 to 24 hours (48 hours for oxidase positive and non-fermenter bacilli)
• The GN A strip, with 12 substrates, can be used separately to identify the most commonly encountered Enterobacteriaceae, or used with the GN B strip for total of 24 substrates, to identify a much more extensive list of gram negative bacteria, including oxidase positive bacilli and non-fermenters
• The dehydrated substrates in each well are reconstituted with a saline suspension of the organism to be identified
• If the individual substrates are metabolized by the organism, a color change occurs during incubation or after addition of specific reagents
• The GN A microwell strip is intended for the identification of the oxidase negative, nitrate positive glucose fermenters comprising the most commonly occurring genera of the family Enterobacteriaceae (28 genera and 45 species)
• Substrates included: Lysine, Ornithine, H2S, Glucose, Mannitol, Xylose, O.N.P.G., Indole, Urease, V.P., Citrate, T.D.A.
• A pure 18-24 hour culture of the bacterial isolate to be identified must always be used; an oxidase test must be carried out on the isolate prior to microwell test strip inoculation
