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.
