Researchers from the University of Sheffield have discovered potential new treatments for diabetic foot ulcers, a condition often challenging to treat, from an unconventional source: the feces of endangered animals.

By studying waste from animals like Guinea baboons, lemurs, and Visayan pigs, the researchers found bacteriophages capable of combatting hard-to-treat diabetic ulcers, promising a breakthrough that could alleviate substantial medical costs and improve quality of life.

The Unlikely Solution

Scientists led by Professor Graham Stafford, a molecular microbiologist from the University of Sheffield, focused on isolating bacteriophages, viruses that selectively target and kill bacteria, from the fecal matter of endangered animals at Yorkshire Wildlife Park.

These bacteriophages, or phages, have demonstrated efficacy against antibiotic-resistant bacterial species responsible for causing foot ulcers in diabetic patients, presenting a potential alternative for treatments.

Addressing a Pressing Medical Challenge

Diabetic foot ulcers are a prevalent complication of diabetes, affecting an estimated 25% of diabetic patients.

With the number of diabetics continually rising, and conventional antibiotic treatments often proving ineffective due to resistant bacteria, finding alternative treatments is imperative.

Around 60,000–75,000 people receive treatment for diabetic foot ulcers weekly in England alone, and the ineffective treatments lead to approximately 7,000 amputations annually.

Conservation and Healthcare Hand in Hand

The feces from a variety of endangered species such as giraffes, lemurs, and Visayan pigs are showing promising results in the ongoing research.

This innovative research not only presents potential medical breakthroughs but also highlights the importance of conservation efforts and biodiversity, drawing attention to the interconnectedness of life and the potential contributions of endangered species to human health.

Phage Therapy: A Potential Game-Changer

Phage therapy has been minimally utilized in the U.K., primarily for sepsis and a few diabetic foot infections.

However, this research endeavors to explore the potential of environmentally occurring phage on a broader scale, focusing specifically on waste from endangered species.

If successful, phage therapy could revolutionize the treatment of diabetic foot ulcers, reducing reliance on antibiotics, minimizing the need for surgery, and improving patients’ quality of life.

Future Directions and Clinical Trials

While the identification of helpful bacteriophages in animal waste is promising, clinical trials to validate the efficacy of phage therapy for diabetic foot ulcers are yet to be undertaken.

The ongoing research aims to explore phages from various sources and their potential in creating effective therapies for patients struggling with antibiotic-resistant infections.


The groundbreaking research at the University of Sheffield is blending conservation with innovative healthcare solutions.

By isolating bacteriophages from the feces of endangered species, the researchers are exploring new avenues to treat antibiotic-resistant infections in diabetic foot ulcers, potentially saving thousands from amputations and improving the quality of life for many.

This research emphasizes the interconnectedness of all life and how conservation of biodiversity can have unforeseen and far-reaching benefits, echoing the significance of protecting the endangered species and their habitats.
