Multiple Choice

Which organism matches the profile NLF; VP negative; Non-motile; A/A?

A single Gram-negative rod that fits this profile is Yersinia enterocolitica. The combo of non-lactose fermentation, VP negativity, non-motility, and acid production in glucose under both aerobic and anaerobic conditions (A/A) points to Yersinia. Aeromonas hydrophila and Pseudomonas aeruginosa are typically motile, which conflicts with the non-motile clue, and Alcaligenes faecalis is usually motile as well, so they don’t fit the full profile. Yersinia’s traits align with being non-lactose fermenting, VP negative, non-motile at body temperature, and fermenting glucose to acid in both conditions, matching the given profile.
