Clay from Kisameet Bay, B.C., used by B.C. First Nations for centuries for its healing properties could be a new weapon in the fight against antibiotic-resistant bacteria, says new research from the University of British Columbia.
The research, published today in the American Society for Microbiology’s mBio journal, recommends the rare mineral clay be studied as a treatment for serious infections caused by the so-called ESKAPE pathogens — Enterococcus faecium, Staphylococcus aureus (also known as MRSA when it becomes resistant to antibiotics), Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species — which cause the majority of U.S. hospital infections and “escape” the effects of antibacterial drugs.
“Infections caused by ESKAPE bacteria are essentially untreatable and contribute to increasing mortality in hospitals,” said co-author Julian Davies in a written statement.
“After 50 years of overusing and misusing antibiotics, ancient medicinals and other natural mineral-based agents may provide new weapons in the battle against multi drug-resistant pathogens.”
The 400 million kilogram clay deposit is on Heiltsuk First Nation traditional territory near Bella Bella on B.C.’s Central Coast.
UBC says the clay has been used to treat conditions like ulcerative colitis, duodenal ulcer, arthritis, neuritis, phlebitis, skin irritation and burns.
When suspended in water, the clay killed 16 strains of ESKAPE bacteria samples from nearby hospitals and waste treatment facilities.
The next stage in clinical evaluation involves detailed clinical studies and toxicity testing.
