SO5 E213 - Episode 213: Micro Minutes: When Bacteria Break the Rules
In this Micro Minutes episode, Luis breaks down classic microbiology traits that usually hold true, but not always. From indole-negative E. coli to non-swarming Proteus and oxidase-negative Pseudomonas, this quick episode highlights real-world exceptions that can catch techs and students off guard. Learn how to spot: • Indole-negative E. coli (98% rule + inactive biotypes) • Lactose-fermenting look-alikes like Citrobacter freundii • Proteus species that don't swarm • Pseudomonas species that test oxidase negative A fast, practical reminder that no single biochemical test should stand alone.
