Genome Breakthrough Raises Hopes of End to Typhoid
Reaney, Patricia


More than 40 researchers in Britain, Denmark, and Vietnam have mapped all the genes in Salmonella typhi, the bacterium that causes typhoid. The genetic map gives scientists hope that a vaccine can be created to wipe out the disease. The bacterium causes disease only in humans and has become resistant to many antibiotics. Each year, typhoid affects 17 million people throughout the world, with about 600,000 deaths.
