Multiple Choice

Which organism matches the profile NLF; Oxidase positive; Alk/ALK; Motile?

Non-lactose fermenting, oxidase-positive, motile Gram‑negative rods form a small group, and the Alk/ALK clue points to organisms with alkali-tolerant or alkali-associated metabolism. Aeromonas hydrophila fits this combination well: it is non-lactose fermenting on MacConkey, oxidase positive, and motile with a polar flagellum, and it is known to tolerate alkaline conditions in certain media. It is a classic aquatic organism that can cause wound and GI infections, making it a common clinical example for this profile. That combination helps distinguish it from other nonfermenters like Pseudomonas and Alcaligenes, and from the Gram-positive Streptococcus.
