In triple sugar iron test k/a means
WebThe bacteria quickly metabolized the glucose, initially producing an acid slant and an acid butt (acid over acid; A/A) in a few hours. The Emben-Meyerhof-Parnas pathway was used both aerobically (on the slant) and anerobically (in the butt) to produce ATP and pyruvate. On the slant, the pyruvate was further metabolized to CO 2, H 2 O, and energy. WebCitrate test – positive (exzept for S. typhi and S. paratyphi A) 4. Urease test – negative. 5. Triple sugar iron test shows: alkaline/acid, S. typhi: speck of H2S present at the junction of slant and butt. 6. Methyl red is positive. 7. Sugar fermentation test: glucose, mannitol, arabinose, maltose, dulcitol and sorbitol are fermented. 8.

Ferric or ferrous ions and sodium thiosulphate are present to detect hydrogen sulfide production. Bacteria that are non-lactose fermenting initially produce a yellow slant ...
Webis oxidase positive and is a glucose oxidizer. It appears to produce H 2 S without the production of acid in the butt however, there has to be a pH change to make H 2 S even if it is not observed. So this should still be recorded as K/K or No Change and weak H 2 S. This again shows the need to do an oxidase test first.
