SILVER SPRING, Md., May 19, 2011 /PRNewswire-USNewswire/ -- On May 18, the U.S. Food and Drug Administration cleared the first test to help determine whether a pregnant woman or a person with swollen lymph nodes testing positive for toxoplasmosis, sometimes known as cat scratch disease, developed the infection within the past four months. (Logo: http://photos.prnewswire.com/prnh/20090824/FDALOGO) Toxoplasmosis is caused by the parasite Toxoplasma gondii. The infection can cause serious...

Researchers tracking the spread of Toxoplasma gondii "“ a parasite that reproduces only in cats but sickens and kills many other animals "“ have found infected wildlife throughout a 1,500-acre (600-hectare) natural area in central Illinois.The researchers also found dozens of free-ranging cats in the area, the Robert Allerton Park, near Monticello, Ill. Two years of tracking, trapping and motion-triggered night photography at eight sites in the park found no evidence of bobcats,...

A safer and more effective treatment for 10 million people in developing countries who suffer from infections caused by trypanosome parasites could become a reality thanks to new research from Queen Mary, University of London published today (15 April). Scientists have uncovered the mechanisms behind a drug used to treat African sleeping sickness and Chagas disease, infections caused by trypanosome parasites which result in 60,000 deaths each year. The study, appearing in the Journal of...

New research reveals how biological arms races between cuckoos and host birds can escalate into a competition between the host evolving new, unique egg patterns (or 'signatures') and the parasite new forgeries. Brood parasitic birds such as cuckoos lay eggs that mimic those of their hosts in an effort to trick them into accepting the alien egg and raising the cuckoo chick as one of their own. New research from the University of Cambridge has found that different bird species parasitized by...

Fresh insight into the way the parasite that causes malaria reproduces could lead to new treatments to help curb the spread of the disease Fresh insight into the way the parasite that causes malaria reproduces could lead to new treatments to help curb the spread of the disease. Scientists studying the disease have found that upsetting the parasite's reproductive strategy could prevent infections from transmitting from person to person. Researchers at the Universities of Edinburgh and Oxford...

NIH-funded study finds way to reduce transmission of malaria to humans Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans, according to a new study published in the journal Science. Funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, the study was led by Raymond J. St. Leger, Ph.D., of the...

An Anglo-Swiss research project has found that the impact of disease-resistant genetically-modified wheat plants on insects may be negligible. Many studies have looked at the effects of genetically-modified (GM) plants on single non-target insects. However, agro-ecosystems are characterised by numerous insect species forming food webs. This study is the first to investigate different transgenic disease-resistant wheat lines and their effect on the structure of whole aphid-parasitoid food...

It's a common assumption that animal migration, like human travel across the globe, can transport pathogens long distances, in some cases increasing disease risks to humans. West Nile Virus, for example, spread rapidly along the East coast of the U.S., most likely due to the movements of migratory birds. But in a paper just published in the journal Science, researchers in the University of Georgia Odum School of Ecology report that in some cases, animal migrations could actually help reduce...

Biologist shows why some strains are more dangerous than others About one-third of the human population is infected with a parasite called Toxoplasma gondii, but most of them don't know it. Though Toxoplasma causes no symptoms in most people, it can be harmful to individuals with suppressed immune systems, and to fetuses whose mothers become infected during pregnancy. Toxoplasma spores are found in dirt and easily infect farm animals such as cows, sheep, pigs and chickens. Humans can be...

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

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
