Mosquitoes that carry malaria may have been doing so 100 million years ago

Science Daily - Malaria - February 11, 2019 - 21:39
The anopheline mosquitoes that carry malaria were present 100 million years ago, new research shows, potentially shedding fresh light on the history of a disease that continues to kill more than 400,000 people annually.

Genome scientists develop novel approaches to studying widespread form of malaria

Science Daily - Malaria - February 8, 2019 - 21:14
Scientists have developed a novel way with genome sequences to study and better understand transmission, treat and ultimately eradicate Plasmodium vivax, the most widespread form of malaria.

Putting female mosquitoes on human diet drugs could reduce spread of disease

Science Daily - Malaria - February 7, 2019 - 19:22
Researchers report that they have identified drugs that can reduce mosquito hunger for blood. Because movement of female mosquitoes from human to human -- male mosquitoes do not consume blood -- is the means by which mosquito-borne infections are passed along, researchers have theorized that reducing the frequency with which female mosquitoes feed is one way to lessen the spread of disease.

Genome structure of malaria parasites linked to virulence

Science Daily - Malaria - February 4, 2019 - 20:40
An international research has found that malaria parasite genomes are shaped by parasite-specific gene families, and that this genome organization strongly correlates with the parasite's virulence. The findings highlight the importance of spatial genome organization in gene regulation and the control of virulence in malaria parasites.

Male birth control for the malaria parasite

Science Daily - Malaria - January 31, 2019 - 19:33
Disrupting two genes involved in the preservation of RNA molecules inhibits the ability of the male form of the malaria parasite to mature and be transmitted from human blood into mosquitoes, interrupting a key stage in the parasite's life-cycle and cutting off an important step in the spread of the disease.

Insecticide resistance genes affect vector competence for West Nile virus

Science Daily - Malaria - January 31, 2019 - 16:38
In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes, it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers demonstrate that mechanisms of insecticide resistance, observed in Culex quinquefasciatus vector, impact the transmission of West Nile virus.

To halt malaria transmission, more research focused on human behavior needed

Science Daily - Malaria - January 22, 2019 - 17:55
Wherever possible, researchers should not just focus on mosquito behavior when working to eliminate malaria, but must also consider how humans behave at night when the risk of being bitten by an infected mosquito is highest.

Mosquito known to transmit malaria has been detected in Ethiopia for the first time

Science Daily - Malaria - January 16, 2019 - 14:06
A type of mosquito that transmits malaria has been detected in Ethiopia for the first time, and the discovery has implications for putting more people at risk for malaria in new regions.

Study: 'Post-normal' science requires unorthodox communication strategies

Science Daily - Malaria - January 14, 2019 - 21:11
Proposals to fight malaria by 'driving' genes that slow its spread through mosquitoes is a high-risk, high-reward technology that presents a challenge to science journalists, according to a new report aimed at stimulating a fruitful, realistic public discussion of 'post-normal' science and technology.

Parasites from patients with cerebral malaria stick preferentially in their brains

Science Daily - Malaria - January 11, 2019 - 14:51
Scientists have provided, for the first time, evidence which links the ability of red blood cells infected with the malaria parasite to bind to the cells lining the blood vessels of the brain, with the clinical syndrome cerebral malaria.

Malaria vaccine passes test in humans

Science Daily - Malaria - January 10, 2019 - 14:39
A vaccine against fatal pregnancy malaria shows promising results in the first tests in humans. The new study has taken a vaccine all the way from discovery of a mechanism through development and production to clinical trials in humans.

Fighting human disease with birth control ... for mosquitoes

Science Daily - Malaria - January 8, 2019 - 19:13
A newly discovered protein that is crucial for egg production in mosquitoes opens a possibility for 'mosquito birth control.' The approach might offer a way to reduce mosquito populations in areas of human disease transmission without harming beneficial insects such as honey bees.

Pyronaridine-artesunate for treating uncomplicated Plasmodium falciparum malaria

Science Daily - Malaria - January 8, 2019 - 15:12
Researchers have looked at the efficacy of using a novel artemisinin-based combination therapy (ACT), pyronaridine-artesunate, to treat malaria in areas where resistance to other ACTs is becoming a problem. The analysis finds it at least as effective as the currently used ACTs, if not better.

For first time, researchers can measure insecticide on surface of mosquito nets

Science Daily - Malaria - January 2, 2019 - 17:54
Insecticide-infused mosquito netting is in widespread use around the world to limit the spread of mosquito-borne diseases, such as malaria. Researchers have now come up with a technique that measures how much insecticide is found on the surface of these nets -- paving the way for efforts to determine how long the nets are effective.

Gold-complexed ferrocenyl phosphines as potent antimalarials

Science Daily - Malaria - December 19, 2018 - 16:56
Researchers have developed novel ferrocene-based molecules that impair the malaria parasite's metabolic function leading to parasite death.

Killing the liver-stage malaria parasite with baculovirus: a drug discovery approach

Science Daily - Malaria - December 12, 2018 - 15:46
Currently, few antimalarial treatments exist that effectively kill liver-stage malaria parasite Plasmodium vivax, which can lay dormant for months or even years. Researchers have reported a new drug that could eliminate liver-stage malaria parasites completely. Using an insect virus, known as a baculovirus, the researchers investigated the ability of baculovirus to mediate innate immunity against malaria infection. This work could pave the way for developing new and more effective antimalarial treatments.

Buzz! Slap! Ow! Taking the virus out of a mosquito's bite

Science Daily - Malaria - December 12, 2018 - 14:33
They approach with the telltale sign -- a high-pitched whine. It's a warning that you are a mosquito's next meal. But that mosquito might carry a virus, and now the virus is in you. Now, with the help of state-of-the-art technology, researchers can see how a virus moves within a mosquito's body, which could lead to the prevention of mosquitoes transmitting diseases.

Half a million tests and many mosquitoes later, new buzz about a malaria prevention drug

Science Daily - Malaria - December 6, 2018 - 19:12
Researchers spent two years testing chemical compounds for their ability to inhibit the malaria parasite at an earlier stage in its lifecycle than most current drugs, revealing a new set of chemical starting points for the first drugs to prevent malaria instead of just treating the symptoms.
