Artemisinin is a frontline drug in the fight against malaria. It's used around the world, and can clear the infection in just a few days.
But reports of resistance began to emerge in western Cambodia in 2008, and this has now spread to other areas in South East Asia.
To investigate, scientists sequenced the genomes of more than 800 malaria-causing parasites collected from all around the world.
They found that some of the strains present in Cambodia were significantly different to the rest, and these were able to withstand artemisinin treatment.
The researchers don't yet know how the parasites are beating the drugs.
But they say understanding their genetic fingerprint will help them to quickly detect and track these strains if they spread.

frontline (leading, most important): tiên phong, hàng đầu, quan trọng nhất
resistance (the ability not to be affected or harmed by something, especially a drug): khả năng kháng lại, cưỡng lại, kháng (thuốc)
emerge (appear, become known): xuất hiện, hiện ra
sequenced the genomes (determined DNA -the order of genetic material): quyết định, sắp xếp trật tự gien
parasites (plants or animals that live in or on other plants or animals and feed on them): ký sinh trùng
strains (types): giống
withstand (to be strong enough not to be harmed or destroyed by something; resist): chịu đựng được, chống cự, cưỡng lại
genetic fingerprint (the unique pattern of a plant or animal's genes):
detect (to discover something, often using special equipment): phát hiện
track (follow the movement or development of something): lần theo dấu vết, theo sự di chuyển
