It has been believed that consuming cranberry products has been anecdotally associated with prevention of urinary tract infections (UTIs) for over 100 years.
In recent years, some studies have suggested that cranberries prevent UTIs by hindering bacteria from sticking to the walls of the urinary tract, thanks to phytochemicals known as proanthocyanidins (PACs).
Yet the mechanisms by which cranberry materials may alter bacterial behaviour have not been fully understood.
Now, researchers in McGill University’s Department of Chemical Engineering are shedding light on the biological mechanisms by which cranberries may impart protective properties against urinary tract and other infections.
Two new studies, spearheaded by prof Nathalie Tufenkji, add to evidence of cranberries’ effects on UTI-causing bacteria.
The findings also point to the potential for cranberry derivatives to be used to prevent bacterial colonisation in medical devices such as catheters.
The study is published online in the Canadian Journal of Microbiology.
