When a male rat senses the presence of a fetching female rat, a certain region of his brain lights up with neural activity, in anticipation of romance. Now Stanford University researchers have discovered that in male rats infected with the parasite Toxoplasma, the same region responds just as strongly to the odor of cat urine. Is it time to dim the lights and cue the Rachmaninoff for some cross-species canoodling? "Well, we see activity in the pathway that normally controls how male...

A press release from PLoS ONE New research shows how a brain parasite can manipulate rodent fear responses for the parasite's own benefit. The study, authored by Patrick House and Dr. Robert Sapolsky of Stanford University and released this week in PloS One, addressed how the single-celled parasite Toxoplasma gondii makes infected rodents more likely to spend time near cat odors. The study finds Toxoplasma-infected male rats have altered activation in brain regions involved in fear and...

Scientists have created spermless mosquitoes in an effort to curb the spread of malaria. Experts say this could be an important step to reducing the mosquito populations in the wild. Malaria kills about a million people around the world every year and accounts for 20 percent of all childhood deaths in Africa. Scientists injected 10,000 mosquito embryos with tiny fragments of RNA designed to turn off a gene known as zpg. The researchers created about 100 spermless mosquitoes that females...

Novel DNA sensing pathway linked to increased susceptibility to malaria Scientists at the University of Massachusetts Medical School have uncovered a novel DNA-sensing pathway important to the triggering of an innate immune response for malaria. Activation of this pathway appears to stimulate production of an overabundance of type-1 interferon by the immune system that may contribute to inflammation and fever in malaria patients and could play a part in susceptibility for the most common and...

Possible resistance-proof drug pairs found by NIH scientists Numerous potential anti-malarial candidate drugs have been uncovered by investigators from the National Institute of Allergy and Infectious Diseases (NIAID) and the National Human Genome Research Institute (NHGRI), both parts of the National Institutes of Health (NIH). Researchers at the NIH Chemical Genomics Center, administered by NHGRI, used robotic, ultra-high-throughput screening technology to test more than 2,800 chemical...

Until very recently, it was unclear why infection with malaria causes fever and, under severe circumstances, an infectious death. Although the parasite has an abundance of potentially toxic molecules, no one knew which ones were responsible for the inflammatory syndrome associated with disease. Now, a new study identifies a novel DNA-sensing mechanism that plays a role in the innate immune response to the parasite that causes malaria. The findings, published online August 4th by Cell Press in...

Edwards Invites Fans to "Ride Along" as He Learns about Killer Disease and What Americans Can Do to Help NEW YORK, July 29, 2011 /PRNewswire-USNewswire/ -- NASCAR Nationwide Series Champion and driver of the No. 99 Aflac Ford in the Sprint Cup Series, Carl Edwards is partnering with nonprofit organization Malaria No More to join the race to end malaria deaths. The announcement comes just in time for Edwards to take to the track this Sunday, July 31, at Indianapolis Motor Speedway, a...

(Ivanhoe Newswire) -- Killing over 780,000 people each year, malaria is one of the deadliest diseases in the world. Finding a cure has been the goal of scientists for many years. Now a cheap and common medication used to treat lice in children and heartworm in pets, could add malaria to the list of diseases it helps control. According to the World Health Organization, new approaches to combat malaria are in constant demand. Current methods of avoiding transmission rely mainly on sleeping...

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...
