Some disease-causing parasites are known to favor one sex over the other in their host species, and such differences between the sexes have generally been attributed to differences in immune responses or behavior. But in a new article, published February 28 in the magazine section of the online, open-access journal PLoS Biology, David Duneau from Cornell University and Dieter Ebert from the University of Basel now propose that all sorts of characteristics that differ between the sexes of the...

Mosquito Repellant Could Be Frightening For Mosquitoes!

[ Watch the Video ] Repellant overwhelms their odor sensors, scaring them away In a small, narrow, temperature-controlled lab room at Vanderbilt University live some of the most deadly and dangerous animals in the world. "These are Anopheles mosquitoes that still think that they're in Central Africa. We won't tell them any different," says Laurence Zwiebel, professor of molecular biology and pharmacology. Anopheles gambiae mosquitoes can be killers. In warmer climates, the...

Young pigs are known to be particularly susceptible to intestinal problems, which not only discomfort the animals but also slow their growth — and thus increase the cost of meat production.  The most common cause of intestinal problems in suckling pigs is the parasite Isospora suis, which according to the literature can be treated by a class of drugs known as sulfonamides. Anja Joachim and colleagues at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) have...

Worms infecting fish grow 4 times faster at higher temperatures and manipulate the behavior of fish Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures — providing some of the first evidence that global warming affects the interactions between parasites and their hosts. The study from the University of Leicester revealed that global warming had the potential to change the balance between parasite and...

Genetically Modified Mosquito Could Help Battle Dengue Fever
2011-10-31 11:24:38

Scientists have found that a genetically modified mosquito could help tackle dengue fever and other insect-borne diseases. Researchers found that the genetically modified males mated successfully with wild females in a dengue-affected part of the Cayman Islands. They said that mating has not been proven in the wild, and could cut the number of disease-carrying mosquitoes. The World Health Organization (WHO) believes there may be 50 million cases every year. Scientists realized in...

Toxoplasma gondii parasites can invade your bloodstream, break into your brain and prompt behavioral changes from recklessness to neuroticism. These highly contagious protozoa infect more than half the world's population, and most people's immune systems never purge the intruders. Cornell researchers recently discovered how T. gondii evades our defenses by hacking immune cells, making it the first known parasite to control its host's immune system. Immunologists from the College of...

Important implications for global pest-control The diamondback moth, Plutella xylostella, is one of the world's most destructive crop pests. It has developed resistance to many chemical and biological pesticides, and the estimated global cost of controlling this insect is approximately US$1billion annually. In a new article published in the open access journal BMC Genomics, researchers from Australia have identified the genes expressed when the diamondback moth is attacked by a...

Flight attacks of small parasitoid wasps (no larger than 2.0 mm in size) on ant workers have been filmed by José María Gómez Durán from Madrid. The four species of wasps show amazing adaptations and enormous differences in the tactics they use. Two of the four filmed species are new to science and are described by Dr Kees van Achterberg from NCB Naturalis Leiden. The study was published in the open access journal ZooKeys. Ants are a very...

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

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
2014-01-12 00:00:00

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...

Guinea Worm, Dracunculus medinensis
2014-01-12 00:00:00

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...
