A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

Sequenced Malaria Genome Provides Benefits, Difficulties In Finding A Cure

Brett Smith for redOrbit.com - Your Universe Online After sequencing the genome of several malaria-related parasites, scientists found that the protozoans responsible for the deadly disease are very genetically diverse and therefore difficult to eradicate, according to their report published this week in the journal Nature Genetics. While the genomes of the four sequenced strains of Plasmodium vivax, a parasite that infects about 100 million people each year, indicated that...

The deadliest form of malaria is caused the protozoan Plasmodium falciparum. During its life-cycle in human blood, the parasite P. falciparum expresses unique proteins on the surface on infected blood cells. Antibodies to these proteins are associated with protection from malaria, however, the identity of surface protein(s) that elicit the strongest immune response is unknown. Dr. James Beeson and colleagues at the Walter and Eliza Hall Institute of Medical Research in Victoria, Australia...

Vigilance Needed Against Evolution Of More-Virulent  Malaria Shown By Vaccine Research
2012-08-01 07:57:06

Malaria parasites evolving in vaccinated laboratory mice become more virulent, according to research at Penn State University. The mice were injected with a critical component of several candidate human malaria vaccines that now are being evaluated in clinical trials. "Our research shows immunization with this particular type of malaria vaccine can create ecological conditions that favor the evolution of parasites that cause more severe disease in unvaccinated mice," said Andrew Read, Alumni...

Research: Overdiagnosis and mistreatment of malaria among febrile patients at primary healthcare level in Afghanistan: observational study Substantial overdiagnosis and mistreatment of malaria is evident in south and central Asia, warns a study published on bmj.com today. With more than two billion people at risk of malaria in this part of Asia — larger than that of Africa - this is a major public health problem which needs to be confronted, say the authors. Malaria remains one...

Scientists from the Zoological Society of London (ZSL) are the first to document the characteristics of invading parasites, using malaria in New Zealand bird species. The study, published today in Ecology Letters, identifies the factors influencing the success of parasites unintentionally introduced to new environments. Avian malaria is a disease caused by species of parasites, of the genus Plasmodium, which infects birds. Just like human malaria, it is spread by mosquitoes, and the...

Can Genetics Prevent The Transmission Of Malaria?
2012-07-17 07:52:22

redOrbit Staff & Wire Reports - Your Universe Online Malaria kills more than 800,000 people worldwide every year and many of those victims are children. Researchers are now reporting that they have genetically modified a bacterium commonly found in the mosquitos mid gut and found that the parasite that causes malaria in people does not survive in mosquitoes carrying the modified bacterium. The researchers, from the Johns Hopkins Malaria Research Institute, modified the bacterium...
