A chemical ingredient of mouthwash is being hailed as a new weapon against the malaria parasite. Triclosan, also found in acne medications and some deodorants, seems to be able to prevent the growth of Plasmodium falciparum.This is the parasite carried in the saliva of mosquitoes which causes as many as 3.2m deaths worldwide every year.
While a practical way of using the agent has yet to be fully developed, the increasing resistance of the parasite to existing anti-malarial drugs is causing concern to health officials.Any potential new avenue of attack is likely to be fully investigated, particularly as triclosan could prove cheaper to manufacture than many existing antimalarials.

In tests on animals at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore, India, one of the key stages by which a malarial infection develops was inhibited.
