Humans are often infected by parasites, sometimes even several species at a time. Such co-infections are more difficult to treat if the parasites interact with each other. An ecologist from the University of Zurich and his international team have compiled a list of the numerous possibilities as to how parasites can interact: They are most likely to do so indirectly via the food source they share. Over 1,400 species of parasites – viruses, bacteria, fungi, intestinal worms and protozoa...

An article featured in The Journal of Parasitology reviews the history of malaria research and examines the various approaches to that research. (PRWEB) March 03, 2014 Malaria has been around for millennia, and there are written references to it from early societies in China, India, Mesopotamia, Egypt, and Greece. Each year an estimated 500 million people are infected worldwide, making malaria a major public health concern. Some countries still experience malaria epidemics, which can also...

April Flowers for redOrbit.com - Your Universe Online A famous orangutan that lived an extraordinary life, died in a rather extraordinary way as well. Mahal, one of the stars of the Milwaukee County Zoo, was an emblem of survival for a dwindling species. Mahal was born in the Cheyenne Mountain Zoo in Colorado Springs, Colorado, five years ago. He was rejected by his birth mother, which is how he ended up in Milwaukee. The young primate was flown aboard a private jet to a surrogate...

Barbara K. Kennedy, Penn State University 23 February 2014 — Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the...

Infectious Form Of Cat Parasite Found In Western Arctic Beluga
2014-02-14 11:36:06

University of British Columbia University of British Columbia scientists have found for the first time an infectious form of the cat parasite Toxoplasma gondii in western Arctic Beluga, prompting a health advisory to the Inuit people who eat whale meat. The same team also discovered a new strain of the parasite Sarcocystis, previously sequestered in the icy north, that is responsible for killing 406 grey seals in the north Atlantic in 2012. Presenting their findings today at the...

Presence Of Humans, Urban Landscapes Increase Songbirds Illness
2014-02-06 10:15:17

Arizona State University Humans living in densely populated urban areas have a profound impact not only on their physical environment, but also on the health and fitness of native wildlife. For the first time, scientists have found a direct link between the degree of urbanization and the prevalence and severity of two distinct parasites in wild house finches. The findings are published in the Feb. 4 issue of the journal PLOS ONE. A team of researchers from Arizona State University...

Research involving scientists at the University of York has provided important new information about transmission of human leishmaniasis, a group of infectious diseases which kills more than 100,000 people a year. Professor Deborah Smith of the Centre for Immunology and Infection at York, working with colleagues at the Wellcome Trust Sanger Institute and Charles University in Prague, has shown that Leishmania parasites reproduce sexually in the wild. The research, published in PLOS...

A newly identified protein and other proteins it interacts with could become effective targets for new drugs to control the parasite that cause toxoplasmosis, researchers led by investigators at Indiana University School of Medicine have reported. The discovery could also open new research pathways for treatments for malaria. The researchers determined that the protein, an enzyme called GCN5b, is necessary for the Toxoplasma parasite to replicate, so interfering with its activities...

The current issue of the Journal of Parasitology includes an address by the outgoing American Society for Parasitologists (ASP) President, Eric Loker. In the address, Loker focused on helminth control and explained how the number of people with parasitic infections will likely be greatly reduced in the next few decades. Lawrence, Kansas (PRWEB) December 30, 2013 Helminths, or parasitic worms, are an ongoing public health concern. The number of infections has declined in recent decades and...

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....

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...
