The majority of fatal cases of malaria are caused by infection with the parasite Plasmodium falciparum. Most at risk are young children and women who are pregnant. A team of researchers, led by Patrick Duffy, at the National Institutes of Health, Rockville, has now developed an approach to profile P. falciparum parasites in such a way that they are able to identify parasite genes associated with severe infection. In the study, they identified a distinct subset of genes in parasites infecting...

Scientists have discovered a new type of mosquito that is unlike any that have been documented before and could complicate the fight against malaria even further. Scientists from France collected mosquitoes from ponds near villages in Burkina Faso over a four-year period and said they identified some as a subtype of Anopheles gambiae -- which is responsible for most malaria transmissions in Africa. The new subtype is highly susceptible to infection with the malaria parasite and, because it...

In notable back-to-back papers appearing in the prestigioous journal Science in October, teams of researchers, one led by Nora Besansky, a professor of biological sciences and a member of the Eck Institute for Global Health at the University of Notre Dame, provided evidence that Anopheles gambiae, which is one of the major mosquito carriers of the malaria parasite in Sub-Saharan Africa, is evolving into two separate species with different traits. Another significant study appearing in this...

ATLANTA, Nov. 5, 2010 /PRNewswire/ -- A compound found in the skin of grapes and used to make red wine may help fight severe malaria, raising hopes of finding a new adjunctive therapy against an illness that kills an estimated 1 million people a year, according to a study presented today at The American Society of Tropical Medicine and Hygiene 59th Annual Meeting. Resveratrol, which in earlier studies has been found to have beneficial anti-cancer effects and may protect the heart, had...

Two strains of the type of mosquito responsible for the majority of malaria transmission in Africa have evolved such substantial genetic differences that they are becoming different species, according to researchers behind two new studies published today in the journal Science. Over 200 million people globally are infected with malaria, according to the World Health Organisation, and the majority of these people are in Africa. Malaria kills one child every 30 seconds. Today's international...

Scientists at The University of Nottingham and the Wellcome Trust Sanger Institute near Cambridge have pin-pointed the 72 molecular switches that control the three key stages in the life cycle of the malaria parasite and have discovered that over a third of these switches can be disrupted in some way. Their research which has been funded by Wellcome Trust and the Medical Research Council (MRC) is a significant breakthrough in the search for cheap and effective vaccines and drugs to stop the...

The parasite that causes the most deadly strain of malaria in humans appears to have originally crossed the species barrier from gorillas, researchers reported on Wednesday. The scientists analyzed DNA from the droppings of some 3,000 gorillas, chimpanzees and bonobos, and found that the strain of malaria parasite most common in humans is virtually identical to one of many strains that infect gorillas. Beatrice Hahn of the University of Alabama at Birmingham and colleagues used the droppings...

Scientists at the University of Arizona have achieved a breakthrough in the fight against malaria: a mosquito that can no longer give the disease to humans For years, researchers worldwide have attempted to create genetically altered mosquitoes that cannot infect humans with malaria. Those efforts fell short because the mosquitoes still were capable of transmitting the disease-causing pathogen, only in lower numbers. Now for the first time, University of Arizona entomologists have succeeded...

Findings could help inform new malaria control strategies New research published today (17 June) by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) shows that malaria is tens of thousands of years older than previously thought. An international team, led by researchers at Imperial College London, have found that the potentially deadly tropical disease evolved alongside anatomically modern humans and moved with our ancestors as they migrated out of...

Malaria, caused by the parasite Plasmodium falciparum, remains one of the main causes of death worldwide. An international team of researchers lead by Instituto Gulbenkian de Ciência, IGC, scientist Carlos Penha-Gonçalves, has identified the first genetic risk factors for the development of cerebral malaria in Angolan children, a severe manifestation of malaria infection. These findings, just published in the journal Plos One (*), are the outcome of a...
