He used one virulent and one non virulent stains of bacteria to observe transduction. when he injected a mouse with a live non virulent (non capsulated) and a dead virulent (capsulated) bacteria, the mouse dies cuz the plasmids of the virulent bacteria enter into the non virulent bacteria , alter its genetic make up and make them virulent (form a capsule)
