What phenotypic characteristic of Salmonella aids in its identification?

Question

Accepted Answer

∻Answer∻ ⚹ Salmonella can be identified by its ability to ferment glucose with the production of gas, its non-lactose fermenting nature on MacConkey agar, and its production of hydrogen sulfide (H2S) which can be observed as black centers in colonies on Hektoen enteric agar. ⚹ ∻Solution∻ ‖ a ⋮ Glucose fermentation with gas production: Salmonella species can ferment glucose, which leads to the production of gas detectable in laboratory tests. ‖ ‖ b ⋮ Non-lactose fermenting on MacConkey agar: Salmonella does not ferment lactose, which helps differentiate it from other Gram-negative enteric bacteria that can ferment lactose, resulting in colorless colonies on MacConkey agar. ‖ ‖ c ⋮ Hydrogen sulfide production: Salmonella produces hydrogen sulfide (H2S), which reacts with iron in the medium to form black precipitates, seen as black centers in colonies on Hektoen enteric agar. ‖ ∻Key Concept∻ ⚹ Phenotypic characteristics for bacterial identification ⚹ ∻Explanation∻ ⚹ Specific metabolic and biochemical properties are used to identify and differentiate bacterial species, such as the ability to ferment specific sugars and the production of characteristic compounds like hydrogen sulfide. ⚹◊What is the role of flagella in Salmonella identification?⍭ Generate me a similar question◊
