Defining DNA Differences To Track And Tackle Typhoid

For the first time, next-generation DNA sequencing technologies have been turned on typhoid fever -- a disease that kills 600,000 people each year. The study sets a new standard for analyzing the evolution and spread of a disease-causing bacterium: it is the first study of multiple samples of any bacterial pathogen at this level of detail. The results will help to improve diagnosis, tracking the disease and could help to design new strategies for vaccination.
