29 May 2019 --- Cranberry extract makes bacteria more sensitive to antibiotics, which may open new, promising avenues for limiting resistance to these drugs, say Canadian researchers. The findings showed that when treated with molecules derived from cranberries, pathogenic bacteria become more sensitive to lower doses of antibiotics and do not develop a resistance to them. The study was conducted at McGill University and L’Institut national de la recherche scientifique (INRS) in Canada and published in the journal Advanced Science.
