Hidden in the Waves: Vibrio, Pseudomonas and the Dangers of Water to Diabetic Ulcers

This episode explains how common water sources — oceans, lakes, rivers, pools, hot tubs and aquariums — can introduce dangerous microbes into diabetic foot wounds, including Vibrio, Aeromonas, Pseudomonas, Mycobacterium, Candida and molds. Dr. G describes why diabetic wounds are especially vulnerable (poor circulation, neuropathy, impaired immunity), the warning signs of severe infection, and how some organisms can cause rapidly progressive necrosis or chronic non‑healing ulcers. Practical takeaways: avoid water exposure with open wounds, tell your clinician about any water contact, seek prompt evaluation for concerning symptoms, and tailor cultures and antibiotics to possible waterborne pathogens.
