Adult Wild Chimpanzees Have Developed A Certain Immunity Against Malaria Parasites
2013-05-29 09:57:59

Max Planck Institute Wild great apes are widely infected with malaria parasites. Yet, nothing is known about the biology of these infections in the wild. Using fecal 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. The data show a strong association between...

Behavior Of Mosquitos May Be Immune Response, Not Parasite Manipulation
2013-05-22 14:30:43

Penn State 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. "Normally, after a female mosquito ingests a blood meal, she matures her eggs and does not take another one until the meal is digested," said Lauren J. Cator, postdoctoral fellow in entomology and a member of the Center for Infectious Disease Dynamics, Penn State. "If infected,...

Invasive Ladybugs Use Biological Warfare On Native Species
2013-05-17 14:49:56

Brett Smith for redOrbit.com - Your Universe Online 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. According to a new report in the journal Science, the aggressive ladybug´s dominance is being assisted...

Malarial parasite may change mosquito olfactory system, enhance attraction to human odor Mosquitoes infected with the malarial parasite Plasmodium falciparum are significantly more attracted to human odors than uninfected mosquitoes, according to research published May 15 in the open access journal PLOS ONE by James Logan and colleagues from the London School of Hygiene & Tropical Medicine, UK. The authors investigated the response of mosquitoes infected with P. falciparum malaria...

Chronic Disease In Toxoplasma Infections Controlled By Plant Proteins
2013-04-09 10:14:40

University of South Florida University of South Florida-led research sheds light on malaria-related parasite's transition from acute to chronic stage A new discovery about the malaria-related parasite Toxoplasma gondii -- which can threaten babies, AIDS patients, the elderly and others with weakened immune function -- may help solve the mystery of how this single-celled parasite establishes life-long infections in people. The study, led by a University of South Florida research team,...

Screening method created to expedite the development of new drugs in the fight against tropical diseases such as malaria and African sleeping sickness 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. The unique screening method uses yeasts which have been genetically engineered to express parasite and human proteins to identify chemical compounds that target...

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. University of Melbourne researchers have shown for the first time that malaria parasites (Plasmodium falciparum)in the early stages of development are more than 100 times less sensitive to...

The Journal of Parasitology presents a study featuring a new method of identifying parasites in various fish species. The results allow researches to identify known parasites in a similar fish species to estimate parasite compatibility with the host they are studying. Lawrence, KS (PRWEB) February 18, 2013 The Journal of Parasitology — We can learn a lot about fish from their parasites. One population of fish, for instance, might be distinguished from another of the same species by...

Amphibian Biodiversity Makes Entire Ecosystem Healthier
2013-02-14 12:24:37

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Colorado, Boulder shows that the richer the biodiversity of amphibian species living in a pond, the more protection that ecosystem has against parasitic infections. The finding of the study support the broader theory that greater biodiversity in large-scale ecosystems such as forests or grasslands may also provide greater protection against diseases, including those that attack humans. A larger...

Fossilized tapeworm eggs in shark feces may be earliest known example of intestinal parasites in vertebrates A cluster of tapeworm eggs discovered in 270-million-year-old fossilized shark feces suggests that intestinal parasites in vertebrates are much older than previously known, according to research published January 30 in the open access journal PLOS ONE by Paula Dentzien-Dias and colleagues from the Federal University of Rio Grande, Brazil. Remains of such parasites in vertebrates...

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...
