Parasites Not At Home On The Range

By Sonia Fernandez, UC Santa Barbara A new study on parasites that infect a marine snail suggests that though hosts might expand their geographical range, the parasites don’t always follow As climate change shifts the geographic ranges in...

UC Davis A new pathogen has been discovered by scientists investigating major die-offs of pigeons native to North America, according to studies led by the University of California, Davis, and the California Department of Fish and Wildlife. Scientists were able to implicate this new parasite, along with the ancient parasite Trichomonas gallinae, in the recent deaths of thousands of Pacific Coast band-tailed pigeons. The die-offs occurred during multiple epidemics in California’s...

The new issue of The Journal of Parasitology features an article that traces the evolution of paleoparasitology over seven decades. The authors of this article conclude that the 21st century has catapulted paleoparasitology into becoming a sub-discipline of its own with new molecular tools and diagnostics being used for the first time. Lawrence, Kansas (PRWEB) June 19, 2014 Until 2009, paleoparasitology, the study of parasites from the past, had never received recognition for being its...

ETH Zurich Researchers at ETH Zurich have isolated a protein from a fungus of the spruce which combats nematodes. The scientists hope that toxins of this kind will become the basis for the vaccination of livestock or domestic animals against zooparasitic nematodes. Most terrestrial plants enter into biocoenosis with fungi. Both sides benefit: the fungus, which surrounds the small roots of the host plant with a thick felt, supplies the plant with trace elements and water. The plant, in...

University of Montreal New study on parasitoid reveals that heat favours production of male progeny Whether an insect will have a male or female offspring depends on the weather, according to a study led by Joffrey Moiroux and Jacques Brodeur of the University of Montreal's Department of Biological Sciences. The research involved experimenting with a species of oophagous parasitoid (Trichogramma euproctidis), an insect that lays its eggs inside a host insect that will be consumed by the...

University of Iowa It's how life survives in a constantly changing environment In Lewis Carroll’s 1871 classic novel Through the Looking Glass, the Red Queen tells Alice: “Now, here, you see, it takes all the running you can do, to keep in the same place.” Over the years, evolutionary biologists have used the Red Queen’s statement to refer to the “Red Queen” hypothesis, which describes how living organisms, including humans, manage to survive in a changing environment by...

Single Cell Genome Sequencing Of Malaria Parasites
2014-05-11 03:52:59

Wellcome Trust Single-cell genomics could provide new insight into the biology of Malaria parasites, including their virulence and levels of drug resistance, to ultimately improve treatment and control of the disease, according to new research funded by the Wellcome Trust and the National Institutes of Health. The findings are revealed in a study by researchers at the Texas Biomedical Research Institute and published today in the journal Genome Research. Malaria infections commonly...

Lethal Parasite Emerged From Pond Scum
2014-05-12 03:42:06

University of British Columbia A genomic investigation by University of British Columbia researchers has revealed that a lethal parasite infecting a wide range of insects actually originated from pond scum, but has completely shed its green past on its evolutionary journey. A team led by UBC Botany Prof. Patrick Keeling sequenced the genome of Helicosporidium – an intracellular parasite that can kill juvenile blackflies, caterpillars, beetles and mosquitoes – and found it evolved...

Spring is one of the most dangerous seasons for fleas, ticks and other parasites, and experts predict 2014 will be one of the worst years ever for certain parasitic diseases. WESTBROOK, Maine, May 6, 2014 /PRNewswire/ -- All dogs - no matter their breeds, sizes, ages or geographic locations - are at risk of infection from a variety of parasites, including ticks, fleas, roundworms, whipworms and heartworms. And so are dog owners and their families....

An article in The Journal of Parasitology discusses various long-term efforts to control parasitic infections and focuses specifically on improving sanitation within a culturally acceptable framework. The author suggests that a "biodigester" may be a solution to improve sanitation systems in some international regions. Lawrence, Kansas (PRWEB) April 28, 2014 More than 450 million people worldwide, primarily children and pregnant women, suffer illness from soil-transmitted...

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...
