217: Micro Minutes: Don't Let PEA Fool You

PEA agar is often treated as "the gram-positive plate," but that shortcut can lead to real bench-level mistakes. In this MicroMinutes episode, we break down what phenylethyl alcohol agar actually does, why growth on PEA does not automatically mean an organism is gram-positive, and how selective media can change colony appearance and behavior. You'll hear about: • What PEA inhibits — and what it doesn't • Why Pseudomonas aeruginosa can grow quite well on PEA • How colony morphology and hemolysis may differ from blood agar • Why Lancefield grouping should never be performed directly from PEA PEA is a powerful recovery tool — but only when you understand its limitations. Short, focused, and straight from the bench, this is your Micro minutes. Stay connected with Let's Talk Micro: • Website: letstalkmicro.com (https://www.letstalkmicro.com/) • Questions or feedback?
