The parasite that causes the most deadly strain of malaria in humans appears to have originally crossed the species barrier from gorillas, researchers reported on Wednesday. The scientists analyzed DNA from the droppings of some 3,000 gorillas, chimpanzees and bonobos, and found that the strain of malaria parasite most common in humans is virtually identical to one of many strains that infect gorillas. Beatrice Hahn of the University of Alabama at Birmingham and colleagues used the droppings...

The antibacterial ingredient in some soaps, toothpastes, odor-fighting socks, and even computer keyboards is pointing scientists toward a long-sought new treatment for a parasitic disease that affects almost two billion people. Their report on how triclosan became the guiding light for future development of drugs for toxoplasmosis appears in ACS' monthly Journal of Medicinal Chemistry. In the study, Rima McLeod and colleagues point out that toxoplasmosis is one of the world's most common...

Evolutionary timeline determined for malaria parasites in mammals, birds, reptiles Scientists have determined the evolutionary timeline for the microscopic parasites that cause one of the world's most widespread infectious diseases: malaria. Having an understanding of the origins of the lineages of such pathogens, or disease-causing organisms, is fundamental to understanding emerging diseases, according to the researchers. The origin of malaria in humans has been dated to as recent as 10,000...

The limited immune response in the eyes of freshwater fishes has created a great home for parasites, according to research published online in the journal Molecular Ecology. The study provides a lens into the evolutionary world of the larval flukes that parasitize Canadian fish. "Canada probably has the best studied freshwater fish parasites in the world, so we were amazed when we found four times more species of flukes in a few fishes from the St. Lawrence than were previously known in all...

Fresh discoveries about the parasite that causes sleeping sickness could lead to new avenues of research into treatments for the disease. Scientists studying the parasite "“ which is spread by the tsetse fly and infects the blood of people and animals "“ have shed light on how it is able to survive when taken up by a feeding fly. Sleeping sickness is a potentially fatal condition which affects up to 70,000 people in sub-Saharan Africa, and millions more are at risk from the...

Researchers at Queen's University Belfast have discovered animal populations may often be under a much larger threat from parasites than previously recognized. It is widely believed that the absence of parasites in species which 'invade' ecosystems gives these 'invaders' an advantage in their new homes (the 'enemy release hypothesis'). But now, researchers from Queen's have discovered quite the opposite, with the presence of parasites in these invasive species actually increasing the damage...

Researchers at Washington University School of Medicine in St. Louis have identified a parasite protein that has all the makings of a microbial glass jaw: it's essential, it's vulnerable and humans have nothing like it, meaning scientists can take pharmacological swings at it with minimal fear of collateral damage. The protein, calcium dependent protein kinase 1 (CDPK1), is made by Toxoplasma gondii, the toxoplasmosis parasite; cryptosporidium, which causes diarrhea; plasmodium, which causes...

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...
