NTU Research Uncovers How E. faecalis Blocks Chronic Wound Healing, Antioxidants Offer Hope

An international research ‌team led by ⁣Nanyang Technological University,​ Singapore (NTU Singapore), has identified a promising way to help chronic wounds heal faster, even those infected⁣ with antibiotic-resistant bacteria.

Chronic wounds represent a significant and growing​ global health⁤ problem.⁣ approximately 18.6 million people‌ worldwide develop diabetic foot⁢ ulcers each⁣ year.[1] Over a lifetime, ⁣one in three people with diabetes may experience a foot ​ulcer.

These⁤ long-lasting wounds often lead to lower ‌limb amputations. Ongoing infections frequently hinder healing, creating ‌a cycle of‌ repeated complications for patients.

In Singapore, chronic wounds like diabetic foot ulcers, pressure injuries, and venous leg ulcers are increasingly⁣ common. ⁤ More than 16,000 cases are reported annually, especially among older adults and​ individuals with diabetes.[2]

How a Common ⁢Bacterium Blocks ​healing

Published in Science Advances,the findings—a collaboration with⁢ researchers⁢ from the ⁤University of Geneva,Switzerland—reveal ​how the widespread bacterium Enterococcus faecalis (E.⁣ faecalis) actively interferes with the body’s ⁤wound-healing process. The team ​demonstrated that blocking this interference allows skin cells to ⁤recover​ and close⁢ wounds.

E. faecalis is an‌ opportunistic pathogen ‍frequently ⁢enough found in chronic infections, particularly diabetic ⁤foot ulcers. ‌These wounds ​are notoriously arduous ​to treat and frequently enough fail to heal, increasing the⁤ risk of serious complications and amputation.

Antibiotic ⁤resistance complicates matters‍ further. ​Some​ E. faecalis strains are ​no longer susceptible to ⁣common antibiotics, making ‍infections harder to control.

Doctors‌ have long recognized that infections slow wound healing,but the underlying biological mechanisms remained unclear ⁢until now.

The study⁢ was jointly led by‍ NTU Associate Professor Guillaume Thibault from the ⁣School of Biological Sciences⁣ and Professor Kimberly kline from‍ the University⁣ of Geneva, who is also a visiting professor at SCELSE –​ Singapore Center for Environmental Life ‍Sciences and Engineering, at NTU.
