The Chronic Wound Microbiome: Dynamics and Treatment Response.
Chronic wounds like diabetic foot ulcers are slow to heal and often become infected, which can lead to amputation. This study looked at the tiny organisms (bacteria and fungi) living in these wounds—called the microbiome—and how they change over time and respond to treatment. Researchers followed a group of patients with chronic wounds, collecting samples regularly to see which microbes were present and how the wound healed. They found that wounds that healed had a more diverse and balanced mix of bacteria, while non-healing wounds were often dominated by harmful bacteria like Staphylococcus. In fact, about 60% of non-healing wounds had high levels of this bacterium, compared to only 20% of healing wounds. The study also found that antibiotic treatment reduced bacterial diversity, which sometimes led to worse outcomes. These findings suggest that simply killing all bacteria may not be the best approach; instead, treatments that promote a healthy balance of microbes could help wounds heal. However, this was a small study, and more research is needed to confirm these results and develop new therapies.
Points clés
- Chronic wounds contain a complex community of bacteria and fungi that changes over time and with treatment.
- Healing wounds tend to have a diverse microbiome, while non-healing wounds are often dominated by harmful bacteria like Staphylococcus.
- Antibiotics can reduce microbial diversity, which may hinder healing by wiping out beneficial bacteria.
- The study found that 60% of non-healing wounds had high levels of Staphylococcus, compared to 20% of healing wounds.
- This research suggests that future treatments might focus on restoring a healthy microbial balance rather than just killing all bacteria.
- Patients should ask their doctor about the role of the wound microbiome and whether probiotics or other microbiome-based therapies might help.

Note de la rédaction
Think of your wound like a garden: a healthy garden has many different plants living together, but if one aggressive weed takes over, nothing else can grow. This research shows that chronic wounds heal better when they have a diverse community of bacteria, not when one harmful type dominates. For someone told their wound won't heal or that amputation is the only option, this opens a new way of thinking—maybe the problem isn't just the wound itself, but the balance of bacteria inside it. At China's specialist DFU centres, doctors are beginning to use microbiome testing and treatments like probiotics or specialized dressings, though it's not yet routine everywhere. For international patients, this means asking about microbiome analysis could be a smart step, and centres that offer it might give you more options than you thought possible.
