NewsResearch on foul odors and open wounds targets flesh-eating screwworm
Scientists are studying foul-smelling substances to figure out what attracts the New World screwworm to its favorite meal – open wounds – to develop better lures for trapping this serious threat to the livestock industry.

NewsStudy uncovers new path toward fighting malaria
Researchers have discovered that the malaria parasite relies on a specific type of fat to survive and multiply within the human host, uncovering a previously unknown vulnerability that could help guide future treatments.

NewsHow the most widespread parasite on earth reads its genome
Researchers have uncovered new details about how Toxoplasma controls the timing of protein production, ensuring the right molecular tools are available exactly when they are needed. Two protein complexes manage this process.

NewsCOVID-19 vaccines remain effective despite helminth-induced immune modulation
In a preclinical study, researchers have found that mRNA- and protein-based SARS-CoV-2 vaccines effectively protected Schistosoma-infected mice against the virus, despite the mice’s distinct immune response profiles.

NewsNew Piem concept proposed: Reshaping human microbiome research and opening a new chapter in precision medicine
Researchers systematically proposed the novel concept of “Persistent Intracellular Extraintestinal Microbes” (PIEM). This expands the scope of microbiome research from external surfaces to the body’s interior.

NewsHow is climate change affecting waterborne diseases?
Researchers find bacteria, viruses and parasites respond differently to climate change, highlighting the need for pathogen-specific public health strategies.

NewsResearchers to tackle overlooked tropical disease
Two researchers are teaming up to build foundational knowledge concerning leishmaniasis, a common, but neglected protozoan parasitic disease. The project combines research into the cell biology of membrane repair with parasitology knowledge.

NewsCould your salad be the source? Pathologist discusses reported parasite outbreak in US
Amid reports of a parasite outbreak that has sickened people in several states across the U.S., a pathologist warns that it is likely linked to a widely distributed commercial food product.

NewsResearchers call for increased screening for parasitic disease linked to HIV and cervical cancer risk
New research has highlighted the need to test millions of women and girls for female genital schistosomiasis (FGS), a neglected disease that can increase the risk of chronic illness, HIV and cervical cancer.

NewsWhen parasites stop having sex, they may become less picky about their hosts
A new evolutionary theory suggests that some asexual parasites may temporarily be able to infect a wider range of hosts as harmful genetic mutations build up.

NewsHigh-resolution DNA typing uncovers hidden diversity of Toxoplasma gondii in China
An international research team has revealed previously hidden genetic diversity in Toxoplasma gondii, a globally distributed zoonotic parasite, in China.

NewsScientists solve decades-old mystery of how malaria parasites invade human cells
Researchers have caught the malaria parasite’s moving junction in the act, obtainingg the first high-resolution view of its three-dimensional structure. It turns out to be a molecular machine that actively remodels the host cell’s membrane to help the parasite force its way inside.

NewsHealthy infant microbiomes appear to protect against malaria
A small preliminary study shows that 6-week-old infants with healthy gut microbiomes are less likely to contract malaria in their first year of life, suggesting the intriguing possibility that treatments such as probiotics could be protective against malaria.
-
NewsNew vaccine offers hope against growing tropical disease in U.S.
Researchers have developed a first-ever vaccine against leishmaniasis, a disease putting 10% of the world at risk. A game changer was the development of CRISPR gene-editing technology.

NewsThe drive to protect Missouri’s $4 billion cattle industry from tick threats
A tiny parasite-carrying tick is posing an outsized threat to Missouri’s cattle. Now, researchers are stepping in to protect the state’s $4 billion cattle industry by tracking different ways the American dog tick spreads a deadly disease known as bovine anaplasmosis.

NewsTropical ocean temperatures drive changes in malaria cases in Malawi
New research shows that temperatures in the tropical Atlantic and Indian Oceans drive year-to-year changes in malaria cases in Malawi.
-
NewsResearchers test two treatments to protect against deadly cattle disease
As cases of a deadly cattle disease rise in Arkansas, researchers are testing two treatments they hope will help ranchers protect their herds. The disease is bovine theileriosis and is caused by the parasite Theileria orientalis Ikeda, carried primarily by the invasive Asian longhorned tick.

NewsPhase 1 clinical trial set to begin on first leishmaniasis vaccine
A phase 1 clinical trial testing the safety of a leishmaniasis vaccine is set to begin in the coming months. The live vaccine, found to be safe in animals, is expected to be tested in humans later this year.

NewsResearchers discover tick protein that may block disease transmission
Researchers have found that ticks produce an exosomal glycine-rich protein that plays a vital role in helping ticks feed and transmit viruses. When they used genetic tools to silence the gene responsible for this protein, ticks lacking the protein struggled to feed effectively and showed reduced body weight after feeding.
