According to a new study from The Cranberry Institute, cranberries shows promise for blunting the spread of hard-to-fight bacterial infections.
CARVER, MASS—Scientists from McGill University and INRS-Institut Armand-Frappier in Canada recently released a novel investigation showing that cranberry extract successfully interrupted the communication between bacteria associated with problematic and pervasive infections.
The authors of the data published in the journal Scientific Reports, Eric Déziel, professor-investigator at INRS-Institut Armand-Frappier and Nathalie Tufenkji, professor at McGill University, state that not only do the results provide insights into how cranberry compounds may work, they also have implications for the development of alternative approaches to control infections.
Previously published work has shown that the American cranberry (Vaccinium macrocarpon L) contains compounds, such as proanthocyanidins (PACs), that provide meaningful antioxidant, anti-adhesion and anti-microbial properties that help fend off illness. Given this, the scientific team hypothesized that cranberries may also have an anti-virulence potential.
They wanted to know if these cranberry compounds could help manage bacterial infections. By feeding fruit flies—a commonly used model for studying human infections—cranberry extract, the team discovered that cranberry provided flies protection from a bacterial infection and they lived longer than their cranberry-free counterparts. In essence, the cranberry extract reduced the severity of the bacterial infection.
Study author Dr. Tufenkji elaborates on what this might mean for humans, as opposed to flies, “This means that cranberries could be part of the arsenal used to manage infections and potentially minimize the dependence on antibiotics for the global public.”
To further explain cranberries’ impact on bacteria, Dr. Déziel says, “Cranberry PACs interrupt the ability for bacteria to communicate with each other, spread and become virulent—a process known as quorum sensing. The cranberry extract successfully interferes with the chain of events associated with the spread and severity of chronic bacterial infections.”
Added to the evidence of cranberry’s role in preventing recurrent urinary tract infections by blocking bacteria from sticking to cell walls, the current study suggests that PACs may help control the virulence or spread of potentially dangerous bacterial infections around the world.

About the Cranberry Institute
The Cranberry Institute is a not-for-profit organization founded in 1951 to further the success of cranberry growers and the industry in the Americas through health, agricultural and environmental stewardship research as well as cranberry promotion and education. The Cranberry Institute is funded voluntarily by Supporting Members that handle, process, and sell cranberries. Supporting Members are represented in national and international regulatory matters and research efforts are done on their behalf.
