Protecting homes with netting window screens can reduce malaria parasite infection

Science Daily - March 21, 2019 - 14:28
Protecting houses against mosquitoes with netting window screens can suppress malaria vector populations and dramatically reduce human parasite infection prevalence, according to new research.

Potential new combination treatment for pancreatic cancer

Science Daily - March 20, 2019 - 20:49
Researchers have identified a possible new therapeutic strategy using two types of drug inhibitors at once to treat one of the world's deadliest cancers.

New mobile element found in mosquito parasite has potential for disease control

Science Daily - March 20, 2019 - 18:10
An interdisciplinary team of scientists has identified a new mobile DNA element in the Wolbachia parasite, which may contribute to improved control strategies for mosquito vectors of diseases such as Dengue and West Nile virus.

Anti-malarial shows promise in human clinical study

Science Daily - March 11, 2019 - 17:31
An experimental drug, called DSM265, cured seven volunteers of a Plasmodium falciparum infection, a malaria parasite that is a major cause of morbidity and mortality worldwide. The goal of this research is to find a cure for malaria with a single dose, and ultimately, eradicate the parasite.

Protection from Zika virus may lie in a protein derived from mosquitoes

Science Daily - March 11, 2019 - 16:53
By targeting a protein found in the saliva of mosquitoes that transmit Zika virus, investigators reduced Zika infection in mice. The finding demonstrates how researchers might develop a vaccine against Zika and similar mosquito-borne viruses, the study authors said.

A quick path to antimalarial resistance

Science Daily - March 4, 2019 - 15:54
Resistance to antimalarial drugs is thought to result mainly from changes in the parasite's genome. However, P. falciparum can also develop resistance to some antimalarial compounds by epigenetic changes, according to a new study. This is of concern because resistance acquired at the epigenetic level can arise quickly, even during the course of a single infection.

Earlier emergence of malaria in Africa

Science Daily - February 28, 2019 - 16:35
Malaria, which claims hundreds of thousands of lives each year -- mainly children and especially in Africa -, is one of the leading causes of death by an infectious agent, the Plasmodium falciparum parasite. In research on malaria, the genetic mutation that causes sickle cell anemia (also known as drepanocytosis), a chronic disease that is often fatal in children under five, caught the attention of the scientific community very early on because it also provides protection against malaria.

Medicating mosquitoes to fight malaria

Science Daily - February 27, 2019 - 18:18
Mosquitoes that landed on surfaces coated with the anti-malarial compound atovaquone were completely blocked from developing Plasmodium falciparum, the parasite that causes malaria, according to new research.

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

Science Daily - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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.

Sex and malaria

Malaria.com news - January 15, 2019 - 10:02
Question: Can malaria be transmitted through oral sex? Answer: No. Malaria cannot be sexually transmitted, including oral sex. Malaria is a vector-borne parasite and is transmitted to humans via the bite of an infected mosquito. As the malaria parasite resides in blood, it can also be transmitted via blood transfusion or via donated organs (though most countries […]

Incomplete Dose of Malaria Drug

Malaria.com news - January 15, 2019 - 09:53
Question: If one doesn’t complete the malaria drug being prescribed, and takes multivitamin due to no appetite towards eating and later stop, does this cause the person spitting uncontrollable. Answer: I am not aware of any link between failure to complete a course of malaria medication and excess saliva, nor any link with taking multivitamins. The main […]

Transfer of parasite to mosquito

Malaria.com news - January 15, 2019 - 09:50
 I am working with rural African communities where we are struggling with contamination of farm products with residues from indoor residual spraying (ban on exports) - and are concerned about contamination of humans as well. Stepped up treatment of all persons diagnosed with malaria with AL. How do the mosquitoes get infected by the parasite so that they can infect humans?
