227: When Gram-Negative Cocci Show Up: How to Think at the Bench
Episode 227
Thursday, 2 April, 2026
In this episode of Let's Talk Micro, we kick off a new series on gram-negative cocci by starting where it all begins—the Gram stain. Seeing gram-negative diplococci on a smear can feel intimidating, especially when you're on the bench and need to make the right call. In this episode, we focus on how to approach that moment with confidence. We walk through the key organisms you'll encounter, including Neisseria, Moraxella, and Veillonella, and discuss how morphology, specimen source, and clinical context all come together to guide your thinking. We also revisit a correction from a previous episode regarding carbohydrate utilization in Neisseria species. This episode is all about building a strong foundation—how to think before jumping to identification. Stay tuned for the next episode, where we'll dive into the media and tests used to identify these organisms in the lab.
