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

Описание: 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.
