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...

The cayenne tick has been identified as one of the vectors of equine piroplasmosis in horses in a 2009 Texas outbreak, according to U.S. Department of Agriculture (USDA) scientists. The United States has been considered free from the disease since 1978, but sporadic cases have occurred in recent years. In October 2009, in Kleberg County, Texas, a mare was presented for veterinary care with clinical signs of infection, including poor appetite and weight loss. Subsequent investigation and...

Researchers at the Perelman School of Medicine at the University of Pennsylvania, Monash University, and Virginia Tech have used a set of novel inhibitors to analyze how the malaria parasite, Plasmodium falciparum, uses enzymes to chew up human hemoglobin from host red blood cells as a food source. They have validated that two of these parasite enzymes called peptidases are potential anti-malarial drug targets. The research appeared in the Aug. 15 early online issue of the Proceedings of the...

Toxoplasma gondii parasites can invade your bloodstream, break into your brain and prompt behavioral changes from recklessness to neuroticism. These highly contagious protozoa infect more than half the world's population, and most people's immune systems never purge the intruders. Cornell researchers recently discovered how T. gondii evades our defenses by hacking immune cells, making it the first known parasite to control its host's immune system. Immunologists from the College of...
