Common Parasite Of Cat Litter May Increase Suicide Risk In Women
2012-07-03 09:11:16

Lawrence LeBlond for redOrbit.com - Your Universe Online What do unwashed vegetables, undercooked meat, and dirty kitty litter all have in common? For one, they are all known to likely harbor a nasty parasite, which in a recent study has been linked as a killer among women who come into contact with the common critter. To be more specific, the parasite -- Toxoplasma gondii -- has been linked with an increased risk of mental health problems and attempted suicide in women who become...

Parasitic Plants Are Stealing Genes From Their Hosts
2012-06-08 07:41:04

New research published today in BioMed Central's open access journal BMC Genomics reveals that the Malaysian parasitic plant Rafflesia cantleyi, with its 50cm diameter flowers, has 'stolen' genes from its host Tetrastigma rafflesiae. Analysis of these genes shows that their functions range from respiration to metabolism, and that some of them have even replaced the parasites own gene activity. Vertical gene transfer is that between parents and their offspring, while horizontal gene...

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team at the University of Pennsylvania has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators such as monkeys, sharks and blue-fin tuna use to hunt their prey. With this new insight into immune-cell movement patterns, scientists will be able to create more accurate models of...

Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

Scientists develop techniques to avoid repeat of red squirrel catastrophe DISASTROUS disease outbreaks like the one which led to the decimation of the red squirrel in Britain can now be avoided through the implementation of new preventive measures developed by UK scientists. Researchers at the Zoological Society of London (ZSL) looked at the disease risks associated with moving wild animals (translocation), and worked out the key baseline data required to predict the outcome of wild...

Emergence of resistance to the drug artemisinin in western Thailand has created a critical point in global efforts to control and eliminate malaria worldwide, according to a new study published in the Lancet, a British Medical Journal, by researchers at the Texas Biomedical Research Institute and their collaborators in Thailand. A second study, published concurrently in the journal Science by the same research groups, identifies a major region of the malaria parasite genome associated with...

Less resistance can sometimes be better than more--at least in a freshwater lake When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests. A freshwater zooplankton species known as Daphnia dentifera endures periodic epidemics of a virulent yeast parasite that can infect more than 60 percent of the Daphnia population. During these epidemics, the Daphnia population evolves quickly, balancing infection resistance and reproduction....

When it comes to battling a deadly parasite epidemic, it may be better not to fight it.  A new study of freshwater zooplankton suggests less is more when it comes to evolving against a parasitic epidemic. The zooplankton, known as Daphnia dentifera, has been found to endure a yeast parasite infection known to affect more than 60% of its population. What scientists found interesting is how quickly the Daphnia population evolves, balancing infection, resistance, and reproduction....

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...
