Also used for treating lice in children and heartworm in pets, ivermectin could add malaria to long list of diseases it currently helps control A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year, according to a new study published today in the July edition of the American Journal of...

When a person living in a malarial area gets a fever, health workers need to know the cause to make absolutely sure they give the right treatment. For many years in sub-Saharan Africa primary health workers have often assumed a fever is caused by malaria, and given antimalarial drugs. This approach means sometimes people receive the wrong treatment for their illness. It also wastes resources and, over time, can promote resistance to available drugs. A new Cochrane Systematic Review examines...

ROCKVILLE, Md., June 29, 2011 /PRNewswire-USNewswire/ -- Sanaria's mission is to develop and commercialize whole-parasite malaria vaccines that confer high-level, long-lasting protection against malaria caused by Plasmodium falciparum and P. vivax. In the process of developing these vaccines, Sanaria has developed the capacity to manufacture and assay malaria parasites and mosquitoes in a highly regulated, cGMP compliant, industrial setting. These parasites, mosquitoes, and assay services...

(Ivanhoe Newswire)--Malaria is a parasitic disease caused by Plasmodium and results in more than 750,000 deaths annually, but what if there was a more effective approach to curing it? Malaria is transported from one person to another by an infected mosquito. When the mosquito bites a human, a parasite called sporozoite is deposited in the skin. It then travels to the liver cells and multiplies to the point of affecting red blood cells and causing clinical symptoms. Common symptoms of malaria...

Malaria is a devastating disease caused by the Plasmodium parasite which is transmitted to humans by infected mosquitoes. Hundreds of millions of new cases of malaria are reported each year, and there are more than 750,000 malaria-related deaths annually. As a result, there is an urgent need for vaccines to combat infection. Now, a new study uncovers a powerful strategy for eliciting an immune response that can combat the parasite during multiple stages of its complex life cycle and describes...

(Ivanhoe Newswire) -- Snug inside a human red blood cell, the malaria parasite hides from the immune system and fuels its growth by digesting hemoglobin, the cell's main protein. The parasite, however, must obtain additional nutrients from the bloodstream via tiny pores in the cell membrane. Now, investigators from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have found the genes that malaria parasites use to create these...

NIH researchers show parasites create feeding ion channels in blood cells Snug inside a human red blood cell, the malaria parasite hides from the immune system and fuels its growth by digesting hemoglobin, the cell's main protein.

Wolbachia are bacteria that infect many insects, including mosquitoes. However, Wolbachia do not naturally infect Anopheles mosquitoes, which are the type that spreads malaria to humans. Researchers at the Johns Hopkins Bloomberg School of Public Health found that artificial infection with different Wolbachia strains can significantly reduce levels of the human malaria parasite, Plasmodium falciparum, in the mosquito, Anopheles gambiae. The investigators also determined that one of the...

Press release from PLoS Genetics A human genetic variant associated with an almost 30 percent reduced risk of developing severe malaria has been identified. Scientists from the Bernhard Nocht Institute for Tropical Medicine (BNITM), Hamburg, and Kumasi University, Ghana, reveal that a variant at the FAS locus can prevent an excessive and potentially hazardous immune response in infected children. The study appears in the open-access journal PLoS Genetics on May 19. Severe malaria is a major...
