(Ivanhoe Newswire) — Malaria is a parasite disease that is passed from one human to another by the bite of infected Anopheles mosquitoes.  The parasites enter the blood stream and infect red blood cells. The disease involves shaking, chills, high fevers, anemia, and flu-like symptoms. There are approximately 300-500 million cases of malaria each year and more than 1 million people die from it, according to the United States National Library of Medicine.  Although most cases...

The discovery by researchers from the Walter and Eliza Hall Institute of a molecule that is key to malaria's 'invisibility cloak' will help to better understand how the parasite causes disease and escapes from the defenses mounted by the immune system. The research team, led by Professor Alan Cowman from the institute's Infection and Immunity division, has identified one of the crucial molecules that instructs the parasite to employ its invisibility cloak to hide from the immune system,...

Genome sequencing helps identify essential protein in disease-carrying parasites Researchers from Boston College have discovered a protein that plays a pivotal role in the progression of the deadly diseases toxoplasmosis and malaria and shown that its function could be genetically blocked in order to halt the progress of the parasite-borne illnesses, the team reports in the current edition of the journal Science. The protein, identified as DOC2.1, plays a similar role in the secretion...

Keep Arms And Legs Hairy To Keep Bed Bugs Away
2011-12-15 12:21:04

Looking to avoid confrontations with bed bugs? You will be better off not shaving your legs according to researchers in the UK. Twenty-nine volunteers bravely tested the theory by Michael Siva-Jothy, from Sheffield University´s Department of Animal and Plant Sciences, BBC News is reporting. Siva-Jothy found that more layers of both long and short body hair near the surface appeared to work as a deterrent to the blood-sucking insects, with the finer hairs acting as an early warning...

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...

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...

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...
