Latest Parasitism Stories
Cats deposit approximately 1.2 metric tons of feces into the environment each year in the US alone. As OB/GYN doctors have known for a long time, that poop is carrying a parasite that is harmful to the fetus of pregnant women.
A recent study featuring work by several UC Santa Barbara scientists focuses on the impact parasites have on food webs, with findings that are expected to alter our picture of who-eats-who.
Parasites comprise a large proportion of the diversity of species in every ecosystem.
Using faecal samples collected from wild chimpanzees, an international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Robert Koch Institute in Berlin has now investigated the effect of the animals’ age on malaria parasite detection rates.
Malaria-carrying mosquitos appear to be manipulated by the parasites they carry, but this manipulation may simply be part of the mosquitos' immune response, according to Penn State entomologists.
German researchers have uncovered another cautionary tale about the importation of a species that quickly becomes an invasive threat. Introduced to Europe and North America for the purpose of controlling pesky greenhouse aphids, the Asian lady beetle escaped into the ecosystem and quickly dominated the local ladybug population.
Mosquitoes infected with the malarial parasite Plasmodium falciparum are significantly more attracted to human odors than uninfected mosquitoes.
University of South Florida-led research sheds light on malaria-related parasite's transition from acute to chronic stage
A novel tool exploits baker's yeast to expedite the development of new drugs to fight multiple tropical diseases, including malaria, schistosomiasis, and African sleeping sickness.
New research has revealed that immature malaria parasites are more resistant to treatment with key antimalarial drugs than older parasites, a finding that could lead to more effective treatments for a disease that kills one person every minute and is developing resistance to drugs at an alarming rate.
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...
