How LDT works
Small larvae, three big jobs.
Maggot therapy is not magic and it is not just "eating." The treatment works through a set of biological actions that help a stuck wound move toward healing: debridement, disinfection, and healing stimulation.
Enzymes soften dead tissue.
Secretions can reduce bacterial burden.
A cleaner wound bed supports repair.
1. Debridement: clearing the roadblock
Dead tissue is more than a surface problem. It can hide infection, slow the movement of healthy cells, and keep a wound trapped in inflammation. Debridement means removing that dead tissue so the wound bed can be seen and treated.
Medical larvae secrete digestive enzymes into the wound. Those enzymes help dissolve dead tissue outside the larva's body, a process called extracorporeal digestion. The softened material is then taken up by the larvae. This is one reason LDT can be selective: the larvae are attracted to the wet, broken-down dead tissue that most needs to leave.
2. Disinfection: changing the wound environment
Chronic wounds often contain bacteria living in sticky communities called biofilms. Biofilms can make infection harder to treat and can interfere with healing. Research has found that larval secretions can have antimicrobial effects against some bacteria and may disrupt parts of the biofilm environment.
This does not mean larvae replace antibiotics or good wound care. It means they may help shift the wound from a dirty, stalled environment toward a cleaner one where other treatments can work better.
3. Healing stimulation: helping the body restart
Once dead tissue is removed and bacterial pressure is lower, the wound has a better chance to form healthy granulation tissue. Studies suggest larval secretions may also influence cell behavior and wound repair signals, including activity linked with growth factors and tissue remodeling.
In plain language: the larvae clean, calm, and nudge. They clean away what should not be there, help calm the microbial burden, and may nudge the wound toward repair.
