A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments by researchers at McGill University.

The findings, which will be published in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage. Overuse of antibiotics fuels the emergence of drug-resistant bacteria, which has become a major public-health concern worldwide.

Prof. Nathalie Tufenkji’s research team in McGill’s Department of Chemical Engineering prepared a concentrated extract of maple syrup that consists mainly of phenolic compounds. Maple syrup, made by concentrating the sap from North American maple trees, is a rich source of phenolic compounds.

The researchers tested the extract’s effect in the laboratory on infection-causing strains of certain bacteria, including E. coli and Proteus mirabilis (a common cause of urinary tract infection). By itself…
