In addition to TDA's killing mechanism, the researchers were interested in understanding the mechanism by which a bacterial strain could become resistant to the antibiotic. (princeton.edu)
In the Lancet article, researchers reported examining blood samples from patients with so-called uncomplicated malaria from a number of sites in Cambodia, Laos, Thailand and Myanmar. (voanews.com)
The researchers are calling for immediate steps to control the spread of the resistant malaria parasite. (malaria.com)
Source: Niraj H. Tolia, WUSTL) Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. (blogspot.com)
This dye binds specifically to the parasite, allowing the researchers to observe the parasites using an advanced microscope. (researchmatters.in)

A drug-resistant strain of malaria has spread through South-East Asia and is on the cusp of reaching India, scientists said in a study published Friday. (khaosodenglish.com)

Dr Aimable Mbituyumuremyi, the Division Manager for malaria and other parasitic diseases at RBC in 2021, said that drones helped in the precision mapping of mosquito breeding sites and in spraying the larvicide. (healthissuesafrica.com)

Meanwhile, efforts to develop new and improved malaria vaccines continue globally, with 16 candidates currently in preclinical development and another 23 in clinical trials. (nih.gov)

Parasitologist Margaret Phillips , a professor and the chair of the biochemistry department at UT Southwestern, and colleagues have been researching interventions for malaria for decades as part of a large multidisciplinary project funded by the National Institutes of Health and sponsored by Medicines for Malaria Venture. (asbmb.org)
Collaborative partnerships with global health organizations, government agencies and philanthropic foundations such as the Medicines for Malaria Venture, The Welch Foundation, the Bill & Melinda Gates Foundation, and National Institutes of Health ensure that their discoveries translate into real-world impact. (asbmb.org)
That may not sound like much, said Timothy Wells , chief scientific officer of the nonprofit Medicines for Malaria Venture . (kunr.org)
Specifically, in the case of the two anti-parasite drugs, it has been far too easy in our own time when scientific advances seemingly flow endlessly from the lab, to forget that less than two centuries ago, most medicines were herbal in nature. (dailymaverick.co.za)
Now, the refined drug, Ivermectin, is so crucial that the World Health Organisation has put it on its list of essential medicines that even the most rudimentary medical system should have. (dailymaverick.co.za)

A major challenge will be to continually assess the changing epidemiology of malaria as control and elimination efforts prove successful to ensure that appropriate tools and interventions are developed and effectively deployed. (nih.gov)
however, the malaria parasites and their mosquito vectors change every day to evade the interventions we use to kill them. (cdc.gov)
It includes interventions such as mass-drug administration programmes , bed-nets, insecticide, molluscicide and larvicide spraying, land-use change, extreme weather events, population increase and economic activities. (theconversation.com)
The accomplishments were made possible by a variety of factors, including RBC's interventions to ensure that services for diagnosing and treating malaria are made more accessible to the public. (healthissuesafrica.com)
Cost-effective interventions require afford- method, a new version of the ICT Pf/Pv, able methods for the rapid and accurate di- showed improved performance over previ- agnosis of malaria to ensure prompt and ous versions in Thailand [ 14 ]. (who.int)

In 2022, the fight against malaria faces new and growing challenges. (healthissuesafrica.com)

Evaluations will continue this year and if all goes smoothly the drug could be ready for clinical trials in 2011. (swissinfo.ch)
Fosmidomycin, an antibiotic, is being evaluated against malaria in Phase 3 clinical trials in combination with other antimalarial drugs. (blogspot.com)
Our data establish a needed baseline for drug susceptibility among clinical isolates and provide a segue for future combination therapy studies as well as research related to phenotypic or genetic differences that could shed light on mechanisms of action or predispositions to specific drugs. (uga.edu)
The data from this study provide a baseline of drug susceptibility among clinical isolates and suggest that new drugs should be tested on a larger number of isolates in the future. (uga.edu)

It was clear that we needed to do something radical to prevent the spread of drug-resistant malaria… to fight fire with fire," says lead researcher Professor Sir Nicholas White . (ox.ac.uk)

Such fungi could become an important malaria intervention if future studies demonstrate that they are safe and effective. (nih.gov)

The best treatments for malaria are artemisinin combination therapy (ACT) drugs, but they are up to 40 times more expensive than the older failing drugs. (swissinfo.ch)

Resistance to chloroquine and sulfadoxine-pyrimethamine, the cheapest malaria drugs, is becoming more common. (swissinfo.ch)
