The segmented worms that were studied by Christer Ers©us, doctoral student Daniel Gustavsson and their American colleague, are identical in appearance. From the very first time that they were described, they have been treated as the same species, and they are also found together in freshwater environments in North America, Sweden and the rest of Europe. But when the researchers examined the worms using advanced methods for DNA analysis, they discovered that they were in fact two...

An international team of biologists has discovered a new species of microsporidia, a single-celled parasite of animals, in a roundworm used in genetic laboratories around the world. The discovery, detailed in the current issue of the journal PLoS Biology, is a breakthrough for public health researchers who until now had been looking for a suitable laboratory model in which to study microsporidia"”a class of emerging pathogens that can cause significant illness in humans. "Microsporidia...

A U.S. study of amphibians suggests diversity itself might lower the chances of developing parasitic infections. The University of Colorado at Boulder study showed American toads who lived with gray tree frogs reduced their chances of parasitic infections known to cause limb malformations. Researchers say their findings have strong implications for the benefits of biodiversity on emerging wildlife diseases. The scientists said their experiments showed when toad tadpoles were raised in...

By DIANA MARRERO By DIANA MARRERO Washington -- Nearly a year after dropping out of the presidential race, Tommy Thompson is turning his attention to worms. Thompson, the former Wisconsin governor who later served as the country's top health official, has teamed up with a nonprofit health organization to fight hookworm, whipworm and other tropical diseases that affect 1 billion of the world's poorest people. He says this type of "medical diplomacy" could help build support for the...

Compounds may provide much-needed new weapons in worldwide battle against schistosomiasisA research team supported by the National Institutes of Health (NIH) Roadmap and the National Institute of Allergy and Infectious Diseases (NIAID) has identified chemical compounds that hold promise as potential therapies for schistosomiasis, a parasitic disease that afflicts more than 200 million people worldwide. The findings were reported yesterday in the advance online publication of the journal...

By Julia Stuart David Pritchard's wife thought he was barking. In the interests of science, the professor of parasite immunology agreed for a plaster bearing 50 hookworms to be stuck on to his skin. They burrowed into his flesh, crawled up his arm, travelled to his lungs and arrived in his gut, where they attached themselves and started to suck out his blood. "My wife said, 'What the hell are you doing? You've got a young family," he says. Mrs Pritchard had already had to put up with her...

DUBLIN -- Scientists in Ireland have discovered that eggs from a parasitic worm may hold the key to treating inflammatory conditions such as lung diseases and the skin complaint psoriasis. Researchers at Trinity College Dublin (TCD) said on Thursday they had found that the worm, schistosoma mansoni, which infects over 250 million people in tropical countries, releases a molecule with strong anti-inflammatory qualities. Padraic Fallon of TCD's School of Biochemistry and Immunology said the...

Tiny worms that can trick the body's natural defences could hold the key to new treatments for a range of conditions, including diabetes, asthma and hay fever. University of Edinburgh scientists, who have discovered that helminth parasites can exploit an 'Achilles heel' in our immune system, now hope to mimic the worms' survival tactics in a bid to beat infection. To find out how helminths fool the body's defences, the team are focusing on the role played by so-called 'regulatory cells',...

The disease is triggered off by the bite of an infected mosquito: together with its anticoagulant the mosquito pumps threadworm larvae into its host's body. These gravitate towards the lymph nodes, where they grow into threadworms which may be up to ten centimetres long. The body reacts by producing inflammation which halts the flow of lymphatic fluid. The consequence of this is that arms, legs and genitals swell to monstrous proportions "“ hence the name elephantiasis. More than 120...

A study of how the body expels parasitic worms has led to a surprising new discovery about the immune system that could help in the treatment of bowel cancer. Scientists investigating whipworms, parasites that infect one-fifth of the world's population as well as livestock and domestic animals, have discovered a new way that the body effectively eliminates the parasites. The University of Manchester research, published in the US journal Science, found the reason why some hosts were able to...

Rodent Tapeworm. Hymenolepis microstoma
2014-01-12 00:00:00

The rodent tapeworm (Hymenolepis microstoma) is a parasitic worm that is classified within the Platyhelminthes phylum. This species affects rodents across the world, causing hymenolepiasis, but it does not often affect humans. Most of the available information regarding tapeworms is derived from the studies conducted on this worm and the other members of its genus, Hymenolepis. These worms have been present in laboratories since the 1950's and can either be raised and kept in a culture or be...

New World Hookworm, Necator americanus

The New World hookworm (Necator americanus) is a hookworm that can be found in the New World. This species, along with other species in the Nematode phylum, is a parasitic worm that is commonly found in cats, dogs, and humans. Infections from this species are known as Necatoriasis. However, there are two common species of hookworm that infest humans, known as the Old World hookworm (Ancylostoma duodenale) and the New World hookworm, so infections are generally known as hookworm infections....

The dwarf tapeworm (Hymenolepis nana) is a species of tapeworm that is classified in the Platyhelminthes phylum. It once held three other scientific names including Vampirolepis nana and Taenia nana. It is found throughout the world but occurs most often in temperate regions. As its common name implies, the dwarf tapeworm is small, reaching an average body length of 1.5 inches. The head, or scolex, holds a retractable beak like organ that has twenty to thirty hooks and four string suckers,...

The Hydatid Worm (Echinococcus granulosus), also known as the Hyper Tape-Worm, is a species of cyclophyllid cestode that is found in the small intestine of adult canids (canine), but also is found in livestock and humans, which serve as intermediate hosts. This specimen causes Hydatid disease. The adult Hydatid worm is typically less than 0.25 inches in length and has three proglottids (segments) when intact: the immature proglottid, mature proglottid and gravid proglottid. This specimen,...

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...
