Latest Parasitism Stories
Someone who thought it worthwhile to analyze the contents of a fifteenth-century cesspit in Jerusalem has struck…parasite eggs. But they reveal an interesting tie between Europe and the Middle East.
Researchers at the University of Leeds, Queen's University Belfast and Stellenbosch University in South Africa looked at cannibalism among freshwater shrimp in Northern Ireland. They found a tiny parasite, Pleistophora mulleri, not only significantly increased cannibalism among the indigenous shrimp Gammarus duebeni celticus but made infected shrimp more voracious, taking much less time to consume their victims.
The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.
An article in the current issue of The Journal of Parasitology looks at why parasites now appear nearly
Malaria parasites invade human red blood cells, they then disrupt them and infect others.
An international research collaborative led by St.
The current issue of The Journal of Parasitology features two studies that test the efficacy of the FLOTAC method, which uses a dual-chamber centrifugation system that detects parasitic eggs and
The authors of an article in The Journal of Parasitology argue that parasitic manipulations do not just target one area, such as growth or reproduction, but many parasites directly affect the
A newly-discovered species of ant supports a controversial theory of species formation. The ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.
More than 300 parasitologists gathered for the American Society of Parasitologists annual meeting to celebrate the 100th anniversary of The Journal of Parasitology.
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 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 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...
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...
