Scientists in Australia have discovered a remarkable thing about an Australian seaweed.The seaweed produces a compound that protects against cholera and other bacterial diseases. The seaweed, Delisea Pulchra, produces furanones that interfere with the signalling mechanism that cholera bacteria use to communicate with each other. The research has been undertaken by Dr Diane McDougald, of the University of New South Wales Centre for Marine Biofouling & Bio- innovation. The cholera bacteria have to sense that there is a "quorum" of enough bacteria before they begin to release toxins.This signalling is also used by the bacteria that cause golden staph.
