Report

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 towithstand 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
resistance：the ability not to be affected or harmed by something, especially a drug
emerge：appear, become known
sequenced the genomes：determined the order of genetic material (DNA)
parasites：plants or animals that live in or on other plants or animals and feed on them
strains：types
withstand：to be strong enough not to be harmed or destroyed by something; resist
