An antimicrobial chemical used in mouthwashes has emerged in the unlikely role of malaria fighter.

In test-tube studies, the compound also kills the parasite responsible for most severe cases of malaria in people, scientists in India report.
The researchers found that triclosan binds to an enzyme called FabI in Plasmodium falciparum, the parasite infecting people.
