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...

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...

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.

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...

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...
