Some Suicide Attempts May Be Blamed On Parasite
2012-08-17 15:24:09

Lee Rannals for redOrbit.com — Your Universe Online A parasite may be to blame for some suicide attempts, according to research appearing in the Journal of Clinical Psychiatry. Toxoplasma gondii, or T. gondii, lies in the bodies of 10 to 20 percent of Americans, but in most it was thought to lie dormant. However, it appears as though the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. “Previous research has found...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

redOrbit Staff & Wire Reports - Your Universe Online Climate change could cause parasites such as tapeworms to become more infectious or malignant, researchers from Oakland University and the University of South Florida claim in a new study gauging the impact of temperature swings on frogs' fungal infection rates. The research, which was published in Monday's edition of the journal Nature Climate Change, shows that tiny parasitic organisms likely have an easier time adapting to...

New research explains why female cuckoos have evolved different guises To minimize the chance of being recognized and thus attacked by the birds they are trying to parasitize, female cuckoos have evolved different guises. The new research, funded by the Natural Environment Research Council, was published today, 03 August, in the journal Science. The common cuckoo (Cuculus canorus) lays its eggs in the nests of other birds. On hatching, the young cuckoo ejects the host's eggs and chicks...

Vigilance Needed Against Evolution Of More-Virulent  Malaria Shown By Vaccine Research
2012-08-01 07:57:06

Malaria parasites evolving in vaccinated laboratory mice become more virulent, according to research at Penn State University. The mice were injected with a critical component of several candidate human malaria vaccines that now are being evaluated in clinical trials. "Our research shows immunization with this particular type of malaria vaccine can create ecological conditions that favor the evolution of parasites that cause more severe disease in unvaccinated mice," said Andrew Read, Alumni...

Scientists from the Zoological Society of London (ZSL) are the first to document the characteristics of invading parasites, using malaria in New Zealand bird species. The study, published today in Ecology Letters, identifies the factors influencing the success of parasites unintentionally introduced to new environments. Avian malaria is a disease caused by species of parasites, of the genus Plasmodium, which infects birds. Just like human malaria, it is spread by mosquitoes, and the...

Can Genetics Prevent The Transmission Of Malaria?
2012-07-17 07:52:22

redOrbit Staff & Wire Reports - Your Universe Online Malaria kills more than 800,000 people worldwide every year and many of those victims are children. Researchers are now reporting that they have genetically modified a bacterium commonly found in the mosquitos mid gut and found that the parasite that causes malaria in people does not survive in mosquitoes carrying the modified bacterium. The researchers, from the Johns Hopkins Malaria Research Institute, modified the bacterium...

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...
