A DNA barcode of malaria parasite

An international team of researchers led by the London School of Hygiene and Tropical Medicine, United Kingdom, has identified segments in the DNA of malaria-causing parasite that point to its region of origin.

The researchers studied Plasmodium falciparum DNA and constructed a barcode of 23 DNA segments that can be used to monitor and contain the import of new malaria cases through international travel.

The barcode could also help public health agencies prevent the spread of drug-resistant malaria from one region to another.
