Welcome to the next episode of the WOrM Podcast 🪱Today we’re looking at a review with a bold idea.Can a tiny nematode help us protect fish, amphibians, reptiles and insects from an increasingly challenging world?The authors argue that the answer could be yes.⸻🧬 The central ideaMicrobes have a huge influence on animal health.They affect:• immunity• metabolism• stress tolerance• development• resistance to diseaseThe challenge is that most wild animals are difficult to study in the laboratory.That’s where Caenorhabditis elegans comes in.Instead of testing hundreds of microbial candidates directly in threatened or difficult-to-maintain species, we can first screen them rapidly in worms.⸻🔬 Why use a worm?C. elegans offers an extraordinary experimental toolkit.Researchers can:• manipulate genes with ease• study host–microbe interactions in real time• follow lifespan and healthspan• measure resistance to pathogens and environmental stress• rapidly test hundreds of microbial strainsMany of the signalling pathways involved in immunity, metabolism and stress responses are remarkably well conserved across the animal kingdom.That makes the worm an ideal discovery platform.⸻🌍 From the lab to wildlifeThe authors propose a simple pipeline.Start by isolating microbes from the animal you want to protect.Screen those microbes in C. elegans.Identify which ones improve resilience.Understand how they work.Then return the most promising candidates to the original species for validation.Rather than replacing studies in wildlife, the worm helps researchers focus on the most promising interventions.⸻🦠 More than probioticsThis isn’t simply about adding beneficial bacteria.It’s about understanding how microbial communities can improve resilience against:• rising temperatures• environmental pollution• infectious disease• habitat change• other environmental stressesAs climate change continues to reshape ecosystems, these questions are becoming increasingly important.⸻🧠 The bigger pictureThis paper reminds us that model organisms are valuable far beyond their own biology.C. elegans isn’t just helping us understand worms.It may help us understand how to improve the health and resilience of entirely different animals.Sometimes the fastest way to protect wildlife begins with one of the simplest organisms in the laboratory.⸻🧠 The take-home messageTiny worms can answer big questions.By combining the experimental power of C. elegans with microbiome research, scientists may be able to discover microbial therapies that improve the resilience of species facing an increasingly uncertain future.⸻📄 Paper discussedSprason, C.; Donkersley, P.; Chin, J.
