Researchers at William & Mary's Virginia Institute of Marine Science reveal that intensification of major oyster disease was due to evolving parasite, not just drought as previously thought.
A faster method for collecting pure malaria parasites from infected mosquitos could accelerate the development of new, more potent malaria vaccines.
A new species of nematode (roundworm), named Cryptaphelenchus abietis, was isolated from bark beetles from a dead log collected in Nagano, Japan. The females of this newly described species can be identified based on the size of the post-uterine sac and the conical tail with an elongate posterior part. The males have seven genital papillae and a narrow bursal flap-like extension. The culturability of this species means it may be useful in further nematode research.
The yellow fever mosquito (scientific name, Aedes aegypti) spreads multiple untreatable viruses in humans and is primarily controlled using a pesticide called permethrin. However, many mosquitoes are evolving resistance to the pesticide. A new study by Karla Saavedra-Rodriguez of Colorado State University and colleagues, published in the journal PLOS Genetics, identifies mutations linked to different permethrin resistance strategies, which threaten our ability to control disease outbreaks.
State-of-the-art video microscopy has enabled Australian researchers to see the molecular details of how malaria parasites invade red blood cells - a key step in the disease.
In places on the front lines of climate change, these disease-spreading insects may become a year-round problem.
Honeybees bring back more than just nectar from their floral feasts and these microbes may help them survive turbulent times.
The team studied blood samples from children from two ethnic groups in remote rural areas of Burkina Faso, Gouin and Fulani, to see how they responded to the malaria parasite Plasmodium falciparum. The team discovered an elevation of immune-dampening steroid molecules and a strong immunosuppressive signature in Gouin children. Studying the enigmatic less malaria-susceptible Fulani ethnic group revealed opposing steroid profiles and stronger immune reactivity to infection.
Sanaria and its collaborators have had to take a step by step empirical approach to optimizing immunization with PfSPZ vaccines to achieve a safe, effective, durable, and broadly protective malaria vaccine. Two recent landmark malaria vaccine studies have moved the optimization process forward and highlighted the strong protective efficacy of Sanaria® PfSPZ-CVac in malaria-naïve adults.
New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.
