People looking forward to eating raw oysters over the holidays will welcome news that scientists are making progress in the fight against a rare but deadly disease associated with the tasty bivalves. Two Florida researchers report curing mice of the disease by using a virus to attack its bacterial source – Vibrio vulnificus. The scientists say the research may lead to techniques to purify oysters after harvest but before they reach raw bars and seafood markets – and might one day result in a better cure for the disease in people. The work, reported in a November article in the journal Infection and Immunity, is part of a growing trend in research to use bacteria-attacking viruses, or “phages,” to cure diseases caused by bacteria.
