Bird nests attract flying insects and parasites due to higher levels of carbon dioxide
Researchers in Spain have examined bird nests in order to understand how flying insects and parasites detect gases as a way to locate their hosts. The study found that nests that had higher concentrations of carbon dioxide attracted more biting midges, a type of insect that carries a common blood parasite that infects local birds. The findings have implications regarding how diseases spread, which will be affected as carbon levels rise due to climate change. (2020-08-05)

New studies show how to save parasites and why it's important
An international group of scientists published a paper, Aug. 1, 2020, in a special edition of the journal Biological Conservation that lays out an ambitious global conservation plan for parasites. A separate paper also found that the responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

Return of the zombie cicadas: WVU team unearths manipulative qualities of fungal-infected flyers
Cicadas infected with the parasitic fungus Massospora unknowingly engage in trickery with their fellow insects, resulting in effective disease transmission, according to West Virginia University-led research. Massospora manipulates male cicadas into flicking their wings like females - a mating invitation - which tempts unsuspecting male cicadas and infects them. (2020-07-27)

The big gulp: Inside-out protection of parasitic worms against host defenses

Immune system adaptations in cavefish may provide autoimmune disease insight
Cavefish may not seem like a big deal. They're small, they live in tucked away places humans rarely go, and they're common enough that you can find them on every continent except Antarctica. But researchers from the Stowers Institute for Medical Research see them as a potential way to understand more about the rise in autoimmune diseases in humans. (2020-07-20)

Two new species of parasite discovered in crabs -- discovery will help prevent infection of other marine species
Two new species of parasite, previously unknown to science, have been discovered in crabs in Swansea Bay, Wales, during a study on disease in the Celtic and Irish Seas. Both species are emerging pathogens, and were discovered infecting the common shore crab, so they could potentially have damaging effects on fisheries and other marine species. The researchers' discovery will help inform measures to reduce this risk. (2020-07-15)

Their new research finds that these parasites could be playing an important role in changing the traits displayed to attract mates early in the process of the creation of new species. (2020-06-24)

How Toxoplasma parasites glide so swiftly (video)
If you're a cat owner, you might have heard of Toxoplasma gondii, a protozoan that sometimes infects humans through contact with contaminated feces in litterboxes. Although harmless to most people, T. gondii can cause serious illness or death in immunocompromised individuals or fetuses of infected pregnant women. Now, researchers reporting in ACS Nano have studied how the microorganism glides so swiftly through mammalian tissues during an infection. (2020-06-17)

Parasitic fungi keep harmful blue-green algae in check
When a lake is covered with green scums during a warm summer, cyanobacteria -- often called blue-green algae -- are usually involved. Mass development of cyanobacteria is bad for water quality. But cyanobacteria can become sick, when for instance infected by fungal parasites. Researchers found out that these infections do not only kill cyanobacteria, they also make them easier to consume for their natural predators. Fungal parasites thus help to slow down the growth of blue-green algae. (2020-06-09)

Urban green spaces can help pollinators -- new research provides basic recommendations
Bee populations are experiencing a global decline as a result of climate change, parasites and pathogens, and pesticide exposure, as well as a lack of foraging resources due to human land use. The good news is that gardens and parks can be valuable sites for providing foraging resources to these urban pollinator communities because of their low pesticide use, complex landscapes, and protected environments. (2020-05-29)

Scientists find out which of the metazoans has the smallest known genome
Researchers at St Petersburg University have deciphered the Intoshia variabili gene, the smallest representative of the parasite from the Orthonectida group. At present, its genome is proved to be smallest among all metazoans and includes only 5,120 genes. Phylogenetic relationships of Orthonectida have remained controversial for a long time. According to recent data from St Petersburg University scientists, these parasites are close to Annelida. (2020-05-20)

The malaria parasite P. vivax can remain in the spleen upon expression of certain proteins
The malaria parasite Plasmodium vivax can adhere to human spleen cells through the expression of so-called variant proteins. These are the conclusions of a study led by the Barcelona Institute for Global health (ISGlobal), an institution supported by 'la Caixa' and the Germans Trias i Pujol Institute (IGTP). The results, published in Proceedings of the National Academy of Sciences, suggest that this could represent an additional challenge to eliminating the disease. (2020-05-18)

Malaria parasite ticks to its own internal clock
Researchers have long known that all of the millions of malaria parasites within an infected person's body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at regular intervals. (2020-05-14)

Discovery of malaria parasite's clock could pave way to new treatments
The parasite that causes malaria has its own internal clock, explaining the disease's rhythmic fevers and opening new pathways for therapeutics. (2020-05-14)

Malaria runs like clockwork; so does the parasite that causes the disease
A new study uncovers evidence that an intrinsic oscillator drives the blood stage cycle of the malaria parasite, P. falciparum, suggesting parasites have evolved mechanisms to precisely maintain periodicity. Understanding the mechanisms underlying the circadian regulation of host-parasite interactions will ultimately lead to new strategies and treatments to prevent and control parasitic infections. Searching for the genetic components and how they interact to produce this clock-like behavior will enable scientists to hopefully disrupt it. (2020-05-14)

Ticking time bomb: Malaria parasite has its own inherent clock
