Only Few Seabird Species Contract Avian Malaria
2011-12-13 04:02:07

Climate differences have less impact on the transmission of blood parasites than expected Seabirds often live in large colonies in very confined spaces. Parasites, such as fleas and ticks, take advantage of this ideal habitat with its rich supply of nutrition. As a result, they can transmit blood parasites like avian malaria to the birds. Scientists from the Max Planck Institute for Ornithology in Radolfzell and a team of international colleagues have investigated whether this affects all...

Worms infecting fish grow 4 times faster at higher temperatures and manipulate the behavior of fish Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures — providing some of the first evidence that global warming affects the interactions between parasites and their hosts. The study from the University of Leicester revealed that global warming had the potential to change the balance between parasite and...

Findings point to the development of novel drugs that could eradicate the disease A international team led by scientists from the Genomics Institute of the Novartis Research Foundation (GNF) and The Scripps Research Institute has discovered a family of chemical compounds that could lead to a new generation of antimalarial drugs capable of not only alleviating symptoms but also preventing the deadly disease. In a study published November 17, 2011, in Science Express, the advance online...

Findings Point to the Development of Novel Drugs that Could Eradicate the Disease LA JOLLA, Calif., Nov. 17, 2011 /PRNewswire-USNewswire/ -- A international team led by scientists from the Genomics Institute of the Novartis Research Foundation (GNF) and The Scripps Research Institute has discovered a family of chemical compounds that could lead to a new generation of antimalarial drugs capable of not only alleviating symptoms but also preventing the deadly disease. In a study...

A study conducted by researchers at the Johns Hopkins Malaria Research Institute and their Zambian colleagues detected contrasting patterns of drug resistance in malaria-causing parasites taken from both humans and mosquitoes in rural Zambia. Parasites found in human blood samples showed a high prevalence for pyrimethamine-resistance, which was consistent with the class of drugs widely used to treat malaria in the region. However, parasites taken from mosquitoes themselves had very low...

Malaria Parasite Discovery May Lead To Vaccine
2011-11-10 14:08:10

[ Watch the Video ] Researchers have revealed a new discovery in understanding how a malaria parasite invades human red blood cells. The team from the Wellcome Trust Sanger Institute said they found that the parasite relies on a single receptor on the red blood cell's surface to invade. Malaria kills about a million people every year, most of them being children in Africa under the age of five. The blood stage of the parasite's lifecycle starts when it invades human red blood...

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...

A Hitchhiker's Guide To The Galápagos

Co-evolution of Galápagos mockingbirds and their parasites Along with the famous finches the Galápagos mockingbirds had a great influence on Charles Darwin's theory of evolution. Now, 176 years later, three of the four mockingbird species are among the rarest birds in the world. New research published in BioMed Central's open access journal BMC Evolutionary Biology untangles the evolutionary relationships between Galápagos mockingbirds and provides...

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...

How diseases are transmitted among humans, other animals, the environment is focus New research aimed at controlling the transmission of diseases among humans, other animals and the environment is being made possible by grants from a collaboration among U.S. and U.K. funding agencies. By improving our understanding of the factors affecting disease transmission, the projects will help produce models to predict and control outbreaks. Funding is from the U.S. National Science Foundation...

Lancet Liver Fluke, Dicrocoelium dendriticum
2014-01-12 00:00:00

The lancet liver fluke (Dicrocoelium dendriticum) is a parasitic worm that is classified within the Platyhelminthes phylum. It is thought to be native to over thirty countries including Switzerland, Spain, Germany, Iran, China, Vietnam, Japan, Ghana, and Nigeria, among many other areas. It is also found in South and North America and in Australia. It is typically found in cattle or other grazing species, so it is thought to prefer a habitat that supports these species. It is similar in...

Profilicollis
2014-01-05 00:00:00

Profilicollis is a genus of acanthocephalan parasites that are found in crustaceans and shorebirds. Profilicollis parasites use decapod crustaceans as intermediate hosts and species of shorebirds as definitive hosts. The parasite first develops in mole crabs of North and South America. After it infects a mole crab, it becomes dormant until the crab is eaten by a suitable bird, such as a Surf scoter or Herring Gull. Once the parasite has passed through the stomach of the bird, it develops...

Moniliformis moniliformis
2014-01-05 00:00:00

Moniliformis moniliformis is a species of acanthocephalan parasite that can infect humans, though it rarely does. Human infections have been reported in the United States, Iran, Iraq, and Nigeria. It has been found in rats all over the world, and usually is found in cats, dogs and, in Poland, red foxes. Intermediate hosts are usually beetles and cockroaches. This parasite, like other acanthocephalans, does not have a digestive tract. It absorbs nutrients through the tegument (external...

Giant Thorny-headed Worm, Macracanthorhynchus hirudinaceus
2014-01-05 00:00:00

The Giant Thorny-headed Worm (Macracanthorhynchus hirudinaceus) is a species of acanthocephalan parasite found in the intestines of pigs and other hoofed animals, and can occasionally appear in humans and dogs. The eggs of this parasite are usually found in scarabaeoid or hydrophilid beetles and other similar insects. Worms of this species range in size from less than four-hundredths of an inch to over 15 inches. It causes enteritis, gastritis or peritonitis in affected hosts. While it...
