Expected Effects Of Climate Change May Lead To Decline Of Snail Fever In Africa
2013-12-13 13:19:49

University of Copenhagen The dangerous parasite Schistosoma mansoni that causes snail fever in humans could become significantly less common in the future a new international study led by researchers from the University of Copenhagen predicts. The results are surprising because they contradict the general assumption that climate change leads to greater geographical spread of diseases. The explanation is that the parasite’s host snails stand to lose suitable habitat due to climate change....

Chemical Modification In Human Malaria Parasite DNA Discovered
2013-12-11 13:24:24

University of California - Riverside Findings by UC Riverside researchers could help build a new drug to kill the deadly parasite that is becoming resistant to existing drugs Say "malaria" and most people think "mosquito," but the buzzing, biting insect is merely the messenger, delivering the Plasmodium parasites that sickened more than 200 million people globally in 2010 and killed about 660,000. Worse, the parasite is showing resistance to artemisinin, the most effective drug for...

Fruit Flies Pickier Than You Think
2013-12-05 19:17:53

Cell Press On your kitchen counter, it might seem as though fruit flies will show up for just about any type of fruit you leave around for them. But when given a choice about where to lay their eggs, those flies will go for citrus most of the time, new work shows. The basis for that seemingly complex food preference is surprisingly simple, according to a report in the Cell Press journal Current Biology on December 5. It boils down to a single odorant receptor found on a single class of...

Treatment Target For Public Health Risk Parasite Identified
2013-11-27 10:34:50

McGill University Health Centre In the developing world, Cryptosporidium parvum has long been the scourge of freshwater. A decade ago, it announced its presence in the United States, infecting over 400,000 people – the largest waterborne-disease outbreak in the county's history. Its rapid ability to spread, combined with an incredible resilience to water decontamination techniques, such as chlorination, led the National Institutes of Health (NIH) in the United Sates to add C. parvum to...

West African Bats Are Hosts To Multitude Of Different Haemosporidian Parasites
2013-10-21 13:55:21

Max Planck Institute In Europe, bats are normally discussed in the context of endangered species threatened by loss of their habitats. However, in recent years, bats have caught the eye of infection biologists. The animals are namely hosts to a surprising number of pathogens, many of which could be dangerous to humans. Scientists at the Max Planck Institute for Infection Biology, the Museum für Naturkunde in Berlin and the American Museum of Natural History have been able to identify in...

Researchers at the University of Georgia have discovered that a combination of two commonly prescribed drugs used to treat high cholesterol and osteoporosis may serve as the foundation of a new treatment for toxoplasmosis, a parasitic infection caused by the protozoan Toxoplasma gondii. They published their findings recently in PLOS Pathogens. Toxoplasma gondii is a parasite capable of infecting nearly all warm-blooded animals. While healthy human adults usually suffer no lasting ill...

The authors of an article featured in The Journal of Parasitology explore parasitic roundworm Baylisascaris procyonis infection rates among animals living near developing land. They discovered the intensity and abundance varied widely depending on the areas' size and connection to other forested areas. Lawrence, Kansas (PRWEB) October 15, 2013 Journal of Parasitology – Any parasite that can spread from wild animals to people is a concern. Even when human infections are rare, as in...

Soaring Variety Of Malaria Parasites Found In Bats
2013-10-07 16:10:08

American Museum of Natural History Researchers have discovered a surprising diversity of malaria parasites in West African bats as well as new evidence of evolutionary jumps to rodent hosts. Led by scientists at the American Museum of Natural History, the Max Planck Institute for Infection Biology, and the Museum für Naturkunde, Berlin, the new study reveals that two bat-infecting parasites are closely related to parasites in rodents that are commonly used to model human malaria in...

Cheats Of The Bird World
2013-09-25 08:49:56

University of Exeter Cuckoo finches that lay more than one egg in their victims' nests have a better chance of bamboozling host parents into fostering their parasitic young, a study has found. Dr Martin Stevens from the University of Exeter and Dr Claire Spottiswoode from the University of Cambridge, with Dr Jolyon Troscianko at the University of Exeter, demonstrated that when African cuckoo finch females lay more than one egg in the same nest of their African tawny-flanked prinia...

Mice Aren't Scaredy-Cats When Infected By Toxoplasma
2013-09-19 13:05:53

Brett Smith for redOrbit.com - Your Universe Online Known to cause spontaneous abortions in pregnant women or death in immune-compromised patients, the parasite Toxoplasma gondii has an even stranger effect in mice – it takes away their fear of cats. The fearless mice are a boon to both cats, which get an easy meal, and the parasite, which gets access to the cat's intestinal track – the only place the parasite can sexually reproduce. According to a new University of California,...

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...
