Parasites May Have Had Role In Evolution Of Sex
What's so great about sex? From an evolutionary perspective, the answer is not as obvious as one might think.
Toxoplasmosis Parasite May Trigger Schizophrenia And Bipolar Disorders
Scientists have discovered how the toxoplasmosis parasite may trigger the development of schizophrenia and other bipolar disorders.

Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host.
New Way The Malaria Parasite And Red Blood Cells Interact
Virginia Commonwealth University Life Sciences researchers have discovered a new mechanism the malaria parasite uses to enter human red blood cells, which could lead to the development of a vaccine cocktail to fight the mosquito-borne disease.
Once-a-month pill for both fleas and ticks in Fido and Fluffy
Scientists in New Jersey are describing discovery and successful tests of the first once-a-month pill for controlling both fleas and ticks in domestic dogs and cats.

Revealing secrets of “African sleeping sickness”
Scientists in the United Kingdom and Russia are reporting identification of a long-sought chink in the armor of the parasite that causes African sleeping sickness
Standardizing estimates of the Plasmodium falciparum parasite rate
The Plasmodium falciparum parasite rate (PfPR) is a commonly reported index of malaria transmission intensity. PfPR rises after birth to a plateau before declining in older children and adults
Genotype-specific interactions and the trade-off between host and parasite fitness
These results highlight the importance of host variation in the determination of parasite fitness traits.
Trichostatin A effects on gene expression in the protozoan parasite Entamoeba histolytica
This work represents the first genome-wide analysis of histone acetylation and its effects on gene expression in E. histolytica.
Giardia Genome Unlocked
Giardia lamblia, one of the most common human parasites in the United States, causes more than 20,000 intestinal infections a year, often through contact with contaminated drinking or swimming water.
Giardia Loses Its Hold On Intestinal Tissue After 'Tonic Shock'
Known in America chiefly as the bane of hikers, the single-celled intestinal parasite Giardia lamblia is a major cause of diarrheal illness worldwide
Sugar Identified As Key To Malaria Parasite Invasion
Researchers have identified a sugar in mosquitoes that allows the malaria-causing parasite, Plasmodium falciparum, to attach itself to the mosquito's gut.
"What makes a host profitable" parasites balance host nutritive resources against immunity"
Scientists based at the Universities of Glasgow, Scotland, and Lausanne, Switzerland, have shown that parasites balance host nutritive resources against immunity.
Progress in understanding the malarial parasite
About 2 million people die of malaria every year, of which more than a million are children in sub-Saharan Africa.
'Golden Bullet' Shows Promise For Killing Common Parasite
Researchers in Australia report development of a new type of gold nanoparticle that destroys the parasite responsible for toxoplasmosis
