Drug-resistant malaria

Artemisinin is a frontline前線,第一線 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對抗 began to emerge出現 in western Cambodia in 2008, and this has now spread蔓延 to other areas in South East Asia. 

To investigate, scientists sequenced the genomes基因組 of more than 800 malaria-causing parasites寄生蟲 collected from all around the world. 

They found that some of the strains菌株 present in Cambodia were significantly different to the rest, and these were able to withstand承受 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偵測 and track跟蹤 these strains if they spread.
