Researchers Discover Natural Compound That Disarms Deadly Superbug

These included both existing drugs and naturally occurring substances, all evaluated for their ability to block staph from binding. One compound stood out. Geranylgeranoic acid (GGA), a fatty acid found in plants such as ginger and turmeric, was shown to disrupt bacterial virulence, including its ability to infect, spread, and defend itself.

GGA made it more difficult for the bacteria to attach to human molecules, including proteins found on the skin and in the bloodstream. It also interfered with the microbes' "sensing" system, limiting their ability to detect and respond to their surroundings.

Disarming Bacteria Without Killing Them "Staph has a diverse arsenal of surface proteins that make it sticky," says Cox, "but this compound interferes with several of them." In collaboration with researchers at Western University, the team tested GGA in mice. The compound prevented the formation of skin lesions caused severity of existing infections.

Anti-adhesives are an emerging area of research aimed at developing new treatments for antibiotic-resistant infections. In the United States, similar work is already in clinical trials.

Researchers are studying mannoside-type blockers, which mimic the binding process E. coli uses to attach to the urinary tract, helping prevent infection without antibiotics." "Anti-adhesives have a lot of potential, and we really must start thinking of more unusual approaches to control bacteria than just simply going after growth," says Cox. "I don't think they would ever replace classic antibiotics, but it's only a good thing to have alternatives to help as well." Expanding the Role of Diet and Natural Compounds Future studies will continue to test GGA in animal models.

Cox and her team are also interested in other fatty acids, such as oleic acid found in olive oil, which may have similar effects.

More broadly, they are examining how diet could play a role in preventing or reducing bacterial infections. "GGA is a naturally occurring fatty acid from turmeric and ginger, which you already think of when you're sick, like when you drink hot ginger lemon tea or eat curry to clear your sinuses," says Ruina Bao, a PhD student in Cox's lab who contributed to the research.

Researchers emphasize that consuming ginger or turmeric is not a substitute for medical treatment. More research is needed to determine how effective GGA is and what dose would be required for therapeutic use.
