Malaria Revealed As Ancient, Adaptive And Persistent Foe One of the most comprehensive analyses yet done of the ancient history of insect-borne disease concludes for the first time that malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys. The findings, presented in a recent issue of American Entomologist by researchers from Oregon State University, are based on the study of insect specimens preserved...

A new research technology is revealing how humans develop immunity to malaria, and could assist programs aimed at eradicating this parasitic disease. Dr Alyssa Barry from the Walter and Eliza Hall Institute´s Infection and Immunity division is using ℠protein microarray´ technology to screen human blood serum samples for immunity to proteins produced by the malaria-causing Plasmodium falciparum parasite. Her research, which determines a person´s immunity to hundreds of...

A new malaria vaccine could be the first to tackle different forms of the disease and help those most vulnerable to infection, a study suggests A new malaria vaccine could be the first to tackle different forms of the disease and help those most vulnerable to infection, a study suggests. The new vaccine is designed to trigger production of a range of antibodies to fight the many different types of parasite causing the disease. Scientists created the vaccine by combining multiple...

Malaria is a major global health concern, and researchers are in need of new therapeutic approaches. To address this concern, a study published Oct. 26 in the online journal PLoS ONE reveals new information about the host cell's treatment of the parasite that causes the disease in mice, opening potential new avenues for research and treatment. The new work, led by Hernando del Portillo of the Barcelona Centre for International Health Research, used a mouse model of malaria infection to...

Researchers at the University of South Florida (USF) College of Public College Health have shown for the first time in a rodent model that the earliest form of malaria parasites can lay dormant in red blood cells and “wake up,” or recover, following treatment with the antimalarial drug artesunate. The study, which appears today in the online journal PLoS ONE, suggests that this early-stage dormancy phenomenon contributes to the failure of artesunate alone, or even combined with...

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC), among others, have taken the first step in developing a new type of vaccine to protect chickens against coccidiosis, the most important parasite of poultry globally. A vaccine of this type -- based on proteins from the coccidiosis bug rather than being derived from a live parasite -- could be produced on a larger scale than is currently possible so could be used to provide much more widespread...

North American babies who acquire toxoplasmosis infections in the womb show much higher rates of brain and eye damage than European infants with the same infection, according to new research from the Stanford University School of Medicine. Eighty-four percent of the North American infants studied had serious complications of the parasitic infection, including calcium deposits in the brain, water on the brain and eye disease that caused visual impairment or blindness. By contrast, few...
