    225: Too Many Bugs, One Culture: A CMPH Guide to Wound Cultures

    Wound cultures are some of the most complex specimens encountered in the clinical microbiology laboratory. Unlike more straightforward cultures, wound specimens often contain multiple organisms, making it challenging to determine which microbes are clinically significant and which represent colonization. In this episode of Let's Talk Micro, Luis is joined by Dr. Christopher Doern and Dr. Alexandra Bryson to discuss the wound culture guidelines from the Clinical Microbiology Procedures Handbook (CMPH) and how they can help laboratorians navigate these challenging cultures. Together, they explore practical approaches to interpreting polymicrobial wound cultures, deciding which organisms to work up, and balancing thorough reporting with antimicrobial stewardship. The discussion also covers specimen collection challenges, the role of Gram stains in evaluating specimen quality, guidance on working up common wound pathogens, and strategies to streamline laboratory workflows. Whether you're a student, a new microbiology technologist, or an experienced laboratorian, this episode offers practical insights to help you confidently approach wound cultures and apply CMPH guidance at the bench.

    224: Micro Minutes: Sometimes Gram Stains Lie

    The Gram stain is one of the most trusted tools in clinical microbiology—but it doesn't always tell the full story. In this Micro Minutes episode, we break down why Gram stains can sometimes be misleading and how factors like culture age, antibiotic exposure, decolorization, morphology, and arrangement can change what you see under the microscope. We also touch on classic troublemakers like Acinetobacter and tiny coccobacilli such as Pasteurella and Haemophilus, and how careful observation can keep you from jumping to the wrong conclusion. Short, focused, and straight from the bench—this episode is all about learning how to interpret Gram stains beyond just purple and pink.

    223: SuperStat to Storytime: Building the Future of Laboratory Medicine

    In this episode of Let's Talk Micro, we step beyond the microbiology bench to talk laboratory medicine, advocacy, and storytelling with fellow medical laboratory scientists and podcasters Stephanie Whitehead and Aaron Odegard. We explore how their work on the SuperStat Podcast is helping amplify the voice of the laboratory through conversations on leadership, access, and visibility. The discussion also highlights Little Lab Learners: ABCs of Laboratory Medicine, a children's book created to introduce laboratory medicine early and inspire future lab professionals. Together, we talk about lab career paths, the impact of automation and the pandemic on lab visibility, and why advocacy doesn't look the same for everyone—but matters now more than ever. This episode is a reminder that the lab's story doesn't end at the bench—it's one we all help tell. 📘 Learn More About Little Lab Learners Little Lab Learners: ABCs of Laboratory Medicine is a children's book created to introduce laboratory medicine early and help kids see lab professionals as scientists, problem-solvers, and essential members of healthcare.
