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...

An international research team using a new combination of approaches has found two genes that may prove of vital importance to the lives and livelihoods of millions of farmers in a tsetse fly-plagued swathe of Africa the size of the United States. The team's results were published today in the Proceedings of the National Academy of Sciences (PNAS). The research, aimed at finding the biological keys to protection from a single-celled trypanosome parasite that causes both African sleeping...

Scientists working in a laboratory at Vanderbilt University have potentially discovered a class of insect repellent that is 1000 times more effective than DEET and works against all types of insects. "It wasn't something we set out to find," said David Rinker, a graduate student who performed the study in collaboration with graduate student Gregory Pask and post-doctoral fellow Patrick Jones. "It was an anomaly that we noticed in our tests." Reported in the online edition of the Proceedings...

New research reveals how biological arms races between cuckoos and host birds can escalate into a competition between the host evolving new, unique egg patterns (or 'signatures') and the parasite new forgeries. Brood parasitic birds such as cuckoos lay eggs that mimic those of their hosts in an effort to trick them into accepting the alien egg and raising the cuckoo chick as one of their own. New research from the University of Cambridge has found that different bird species parasitized by...

An international team of scientists published new research this week on the origins of flies and, and despite popular belief, the common ancestry house flies have with mosquitoes. Researchers, publishing a paper in the Proceedings of the National Academy of Sciences of the USA, said the mosquito branched off the same evolutionary tree as the house fly about 220 million years ago, while the house fly branched off about 170 million years later. While only a few species of flies are commonly...

NIH-funded study finds way to reduce transmission of malaria to humans Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans, according to a new study published in the journal Science. Funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, the study was led by Raymond J. St. Leger, Ph.D., of the...

Research published in Genetics proposes a system for spreading disease-resisting genes in mosquito populations Scientists have modeled a system that may be used to control mosquitoes and the diseases they transmit, without the use of pesticides. In the proposed system, mosquitoes are engineered to carry two genes. The first gene causes males to transmit a toxin to females through their semen. The second gene, when expressed in females, makes them immune to this toxin. This research, published...

Same Proteins Involved, but Cancer Takes Hold When Response Gets Out of Control, CCNY Biologists Report Tiny parasitoid wasps can play an important role in controlling the populations of other insect species by laying their eggs inside the larvae of these species.  A newly hatched wasp gradually eats the host alive and takes over its body.  The host insect is far from defenseless, however.  In Drosophila (fruit flies), larvae activate humoral immunity in the fat body and mount...

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
2014-01-12 00:00:00

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
2014-01-12 00:00:00

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...
