A novel study featured in The Journal of Parasitology compared two lakes in the Adirondacks that are only 2.5 kilometers apart. The research showed that significant differences in parasitism can occur, depending on their ecological history. Lawrence, Kansas (PRWEB) August 14, 2013 Every body of water differs in its ecological makeup, species of underwater organisms, and parasitic communities. However, differences in parasitic communities for the same species of native fish in adjacent...

New York, NY (PRWEB) July 30, 2013 The leading manufacturer and supplier of Siberian pine nut oil, PineNutOil.Org, announces new client testimonials on it's Facebook page, which remind consumers of the oil's all-natural ability to fight parasites and cleanse the human...

Human-driven Change Good For Parasites But Bad For Birds In Argentine Forests
2013-07-16 14:23:56

Wildlife Conservation Society A new report by the Wildlife Conservation Society (WCS) and the Disease Ecology Laboratory of Instituto de Ciencias Veterinarias del Litoral, Argentina (ICIVET LITORAL, UNL-CONICET) shows that increases in precipitation and changes in vegetative structure in Argentine forests -- factors driven by climate change and deforestation in the region -- are leading to increased parasitism of young nesting birds by fly larvae (botflies) of the species Philornis...

Parasites Found In Cat Poop May Pose Serious Health Problem
2013-07-10 08:36:41

April Flowers for redOrbit.com - Your Universe Online Cats deposit approximately 1.3 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 pregnant women. As well, cat litter parasites have been associated with an increased risk in suicide in woman. A new study, published in Trends in Parasitology, reveals that this may indeed be a vast and under-appreciated public health problem....

Food Web Affected By Parasites More Than You Think
2013-06-19 10:15:07

University of California - Santa Barbara Parasites are ubiquitous. They feed on virtually every animal and even on each other. Yet, for all the parasites' collective contributions to biomass and biodiversity, conventional food webs don't account for the presence of these tiny and numerous consumers. 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. The...

Parasites comprise a large proportion of the diversity of species in every ecosystem. Despite this, they are rarely included in analyses or models of food webs. If parasites play different roles from other predators and prey, however, their inclusion could fundamentally alter our understanding of how food webs are organized. In a paper published 11 June in the open access journal PLOS Biology, Santa Fe Institute Professor Jennifer Dunne and her team test this assertion and show that including...

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...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
