Researchers at the University of Southampton have worked out how bacteria defend themselves against viruses called phages and the new insights could be key to tackling antibiotic resistance.

Researchers have demonstrated a novel vaccine delivery method in an animal model, using dental floss to introduce vaccine via the tissue between the teeth and gums. The testing found that the new technique stimulates the production of antibodies in mucosal surfaces, such as the lining of the nose and lungs.
