Abstract: | Control of falciparum malaria infections has been increasingly hampered by the emergence of parasites resistant to chloroquine, pyrimethomine and other standard anti-malarials. Chloroquine-resistant strains of Plasmodium falciparum, for example, which originally appeared in South-East Asia and South America are now found in East Asia and sub-Saharan Africa(1). Attempts to combat this alarming development have to date taken two main forms: (1) the judicious use of existing ontimalarials, preferably in combinations, in an attempt to delay the emergence of resistance; and (2) on aggressive research effort aimed at identifying a new generation of antimalarial drugs. But what i f it became possible to administer an antimalarial drug together with a second drug capable of overcoming resistance to the first? A recent report from Samuel Martin and co-workers at The Walter Reed Army Institute of Research in Washington DC raises just such an intriguing possibility. |
