A recent study suggests that parasites in fish, including threatened species of Oregon coho salmon, may have more profound impacts on fish health than has been assumed, and could be one of the key mechanisms by which habitat and land use changes cause salmon mortality. It's not just the presence or absence of parasites that is important, the research found, but their numbers that can build up over years or decades and ultimately cause major impacts. The study will be published soon in the...

Scientists have created spermless mosquitoes in an effort to curb the spread of malaria. Experts say this could be an important step to reducing the mosquito populations in the wild. Malaria kills about a million people around the world every year and accounts for 20 percent of all childhood deaths in Africa. Scientists injected 10,000 mosquito embryos with tiny fragments of RNA designed to turn off a gene known as zpg. The researchers created about 100 spermless mosquitoes that females...

A new study has revealed in unprecedented detail how parasites use different nutrients needed for growth, providing University of Melbourne researchers with unique drug targets against Leishmania, a tropical parasite that infects 12 million people worldwide and causes 500,000 deaths annually. A team led by Professor Malcolm McConville from the Bio21 Institute, University of Melbourne developed a new analytical method which can be used for many infectious parasites and bacteria. The technique...

Research leads to new "scaling" rule for abundance and production of animals Animal species all follow the same rule for how common they are in an ecosystem, scientists have discovered. And the rule is simple. Everything from birds to fishes, crabs to snails to worms, and the parasitic animals that live inside or on them, follows it. "You can predict how common something might be just by knowing its body weight--how big an individual is--and how high up the food chain it is," says biologist...

It seems we may have parasites to thank for the existence of sex as we know it. Indiana University biologists have found that, although sexual reproduction between two individuals is costly from an evolutionary perspective, it is favored over self-fertilization in the presence of coevolving parasites. Sex allows parents to produce offspring that are more resistant to the parasites, while self-fertilization dooms populations to extinction at the hands of their biological enemies. The July 8...

Pork Tapeworm, Taenia solium
2014-01-12 00:00:00

The pork tapeworm (Taenia solium), also known simply as a tapeworm, is a species of parasitic worm that is classified within the Platyhelminthes phylum. This species infects pigs and humans in many areas of the world including Africa, Southern Europe, Asia, South America, and some areas of North America. This species can cause cysticercosis in its larval stage, which is one of the major causes of seizures in humans. The pork tapeworm can reach an average body length between 2 to 3 meters, but...

Paragonimus westermani

Paragonimus westermani is a species of fluke, or flatworm that is classified within the Platyhelminthes phylum. This species is abundant in South America and Asia and affects the lungs of humans and other hosts. It was first discovered in 1878 in Europe after two Bengal tigers died. In 1879, Ringer found this species in the lungs of a human. Manson and Erwin von Baelz identified the sputum and eggs separately in 1880, after which Manson asserted that a snail was most likely the worm's...

Echinococcus multilocularis is a species of tapeworm that is classified within the Platyhelminthes phylum. It is one of a few worms that cause echinococcosis, a disease that affects many canid species including wolves, coyotes, foxes, jackals, domesticated dogs. Humans can also contract this disease. Adult members of this species can reach an average length of .2 inches, and like other species of tapeworm, its body is segmented by three proglottids. Its head, or scolex, is equipped with...

Trichinella spiralis

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...

The Guinea worm (Dracunculus medinensis) is a species of roundworm with the Nematoda phylum. This species is once ranged throughout Asia and Africa, including the west coasts of Africa in Guinea. Although it is not present in this range anymore, the species retains its common name. It was identified in this area by Carl Linnaeus, who discovered the parasite in many merchants along the coast. Its scientific name was also given due to a large population in one area, called Medina. Dracunculus...
