- 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.
- 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.
- Scientists have sequenced the genome of the Southern house mosquito, providing new insights into the most diverse and widespread of three groups of disease-bearing mosquitoes and shedding new light on the transmission of mosquito-borne diseases such as malaria, encephalitis, West Nile virus and filariasis, international teams of researchers report in the upcoming edition of the journal Science.
- The Culex quinquefasciatus mosquito poses a significant threat to human health as a blood-sucking transmitter of elephantiasis-causing worms and encephalitis-inducing viruses.
- A new technique pioneered at Liverpool School of Tropical Medicine (LSTM) is improving the detection and monitoring of insecticide resistance in field populations of an important malaria-carrying mosquito.
- Anti-malarial drugs are being used inappropriately for sick children in Zambia with fevers and difficulty breathing â€“ a problem that can be addressed by arming community health workers with a simple rapid-diagnostic test and a supply of antibiotics, a study led by a team of Boston University School of Public Health [BUSPH] researchers has found.
- Drug companies may be more willing to develop treatments for neglected diseases including malaria, tuberculosis and leishmanaiasis if the European Union would adopt a "priority review voucher" reward system.
- Malaria remains a serious global health problem, killing more than one million people per year. Treatment of the mosquito-borne illness relies on antibiotics, and the emergence of drug-resistant malaria is of growing concern. In a report published online today in Genome Research (www.genome.org), scientists analyzed the genomic features of a Peruvian parasite population, identifying the genetic basis for resistance to a common antibiotic and gaining new insights that could improve the efficacy of diagnosis and treatment strategies.
Malaria is a mosquito-borne infectious disease caused by eukaryotic protists of the genus Plasmodium. The disease results from the multiplication of Plasmodium parasites within red blood cells, causing symptoms that typically include fever and headache, in severe cases progressing to coma or death. It is widespread in tropical and subtropical regions, including much of Sub-Saharan Africa, Asia, and the Americas.
