[2025-10-02T07:29:00.496778] [PI reasoning] **Evaluating Neisseria gonorrhoeae aspects**

I’m analyzing a multiple-choice question about Neisseria gonorrhoeae. I need to identify which statement is false. It’s a Gram-negative diplococcus, not obligate intracellular but a facultative pathogen. Option B states it's "intracellular obligate," which is incorrect. While Neisseria can show twitching motility due to type IV pili, they're generally non-motile. Catalase and oxidase positive is true for Neisseria. Hence, the answer is B, as it inaccurately describes the organism’s intracellular nature. I’ll quickly gather some evidence for support.
