Read the following extract from an article in National Geographic magazine (September 2017 edition, page 26).
The Brazilian pepper tree, an invasive plant in the southern United States, is showing great potential in the fight against antibiotic-resistant bacterial infections. A team of scientists studied historical accounts of its use in traditional South American medicine from as early as 1648. Focusing their experiments on its fruits, which reportedly were used to treat wounds, they then produced an extract that’s able to disarm a virulent type of Staphylococcus bacterium.
Modern antibiotics are designed to kill bacteria. But some bacterial cells survive and pass on their resistance to their offspring, making it increasingly difficult for physicians to fight tenacious infections that threaten their patients’ lives. The Brazilian pepper tree extract deploys an unconventional tactic against infections. It prevents bacterial cells from communicating, which keeps them from ganging up to create tissue-destroying toxins. That, in turn, gives the body’s immune system a change to mount it’s own defence against the bacteria.
