Since December 2016, Brazil has been grappling with its worst yellow fever outbreak for several decades. Research has now demonstrated that the yellow fever virus can be transmitted via Aedes albopictus, the tiger mosquito. This opportunistic species is capable of colonizing both urban and forest areas.
Researchers have discovered a way to halt the invasion of the toxoplasmosis-causing parasite into cells, depriving the parasite of a key factor necessary for its growth. The findings are a key step in getting closer to a vaccine to protect pregnant women from the parasite Toxoplasma gondii, which carries a serious risk of miscarriage or birth defects.
Researchers have eliminated caged mosquitoes using 'gene drive' technology to spread a genetic modification that blocks female reproduction.
Scientists have found a way to boost the efficacy of the antimalarial drug artemesinin with the help of chemotherapy medicines. Artemisinin works through a 'double whammy' attack on the deadly parasite. The drug damages proteins in malaria parasites and clogs the parasite's waste disposal system, known as the proteasome, which chemo can target.
A study indicates the possibility of using tiny vesicles derived from human immature red blood cell as a vaccine platform.
Researchers have identified compounds that could prevent malaria parasites from being able to infect mosquitoes, halting the spread of disease.
There are more clinical phenotypes of severe malaria than those defined by the World Health Organization (WHO), according to a new study. The results indicate that heart failure can be a pathogenic mechanism of disease, which has implications in the clinical management of these patients.
A new tool uses a smartphone camera, a small 3D-printed box and a simple chemical test to show whether a dead mosquito belongs to the Aedes aegypti species, which carries Zika and other devastating viruses that afflict an estimated 100 million people worldwide each year.
Heartbeat irregularities connected to brain activity abnormalities may lead to the ability to predict eventual epileptic seizures in subjects who suffered physical or infectious brain insults, according to Penn State researchers who studied mouse models of cerebral malaria, which often causes epilepsy in those who survive.
New drug-resistant strains of the parasite that causes malaria tend to evolve in regions with lower malaria risk; in areas with high transmission rates, they get outcompeted by the more common, drug-sensitive strains inside the human host. In high-transmission settings, it takes a long time for drug-resistant strains to take hold, but once they do, they can spread rapidly, according to a new study.
Nearly 700 million people suffer from mosquito-borne diseases -- such as malaria, West Nile, Zika and dengue fever -- each year, resulting in more than 1 million deaths. Today, researchers report a new class of mosquito repellents based on naturally occurring compounds that are effective in repelling the bugs, including those that are resistant to pyrethroid insecticides and repellents.
