Wolbachia are bacteria that infect many insects, including mosquitoes. However, Wolbachia do not naturally infect Anopheles mosquitoes, which are the type that spreads malaria to humans. Researchers at the Johns Hopkins Bloomberg School of Public Health found that artificial infection with different Wolbachia strains can significantly reduce levels of the human malaria parasite, Plasmodium falciparum, in the mosquito, Anopheles gambiae. The investigators also determined that one of the...

Study will be published in Nature Medicine this Sunday, May 15, and may have impact in the fight against the disease A team of researchers have found that pre-existing malaria prevents secondary infection by another Plasmodium strain, the parasite responsible for malaria, by restricting iron availability in the liver of the host. This discovery will be published this Sunday, May 15, in Nature Medicine and has important implications for the management and prevention of malaria, a condition...

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans. According to the study, the Enterobacter bacterium is part of the naturally occurring microbial flora of the mosquito's gut and kills the parasite by producing reactive oxygen species (or free radical molecules). The study is published in the May 13 edition of...

Using a pair of powerful genome-search techniques, researchers from the Harvard School of Public Health (HSPH), Harvard University, and the Broad Institute have identified several genes that may be implicated in the malaria parasite's notorious ability to rapidly evade drug treatments. Further testing revealed that one of the genes, when inserted into drug-sensitive parasites, rendered them less vulnerable to three antimalarial drugs. The successful experiments suggest that the genomic...

Almost 3.3 billion people, half of the world's population, risk being infected with malaria. Despite having effective means against malaria, the WHO reports 250 million cases of malaria each year and more than 700,000 related deaths. Researchers at the University of Copenhagen have now discovered that EPO, the doping drug known from professional cycling, can significantly reduce cerebral malaria related deaths. When more than 700,000 people die from malaria each year it is due to two grave...

Scientists have developed a method of genetically manipulating large populations of mosquitoes, which could one day be used to significantly reduce the spread of the deadly malaria parasite to humans. The researchers found that after making specific genetic changes to a few mosquitoes, and then letting them breed, these genetic alterations could be spread through large mosquito populations in just a few generations. The system, known as a gene drive mechanism, was published online Wednesday...

Scientists at Imperial College London and the University of Washington, Seattle, have taken an important step towards developing control measures for mosquitoes that transmit malaria Scientists at Imperial College London and the University of Washington, Seattle, have taken an important step towards developing control measures for mosquitoes that transmit malaria. In today's study, published in Nature, researchers have demonstrated how some genetic changes can be introduced into large...

A group of researchers from EPFL's Global Health Institute (GHI) and Inserm (Institut National de la Sant© et de la Recherche M©dicale, the French government agency for biomedical research) has discovered that a class of chemotherapy drugs originally designed to inhibit key signaling pathways in cancer cells also kills the parasite that causes malaria. The discovery could quickly open up a whole new strategy for combating this deadly disease. The research, published online in the...

NIH-funded study finds way to reduce transmission of malaria to humans Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans, according to a new study published in the journal Science. Funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, the study was led by Raymond J. St. Leger, Ph.D., of the...

There are over 200 million cases of malaria each year and, according to the World Health Organisation, in 2009 malaria was responsible for 781,000 deaths worldwide. Malaria is spread by mosquitoes which breed in open water and spend much of their larval stage feeding on fungi and microorganisms at the water surface. New research published in BioMed Central's open access journal Parasites and Vectors presents a method of dispersing pathogenic fungi as a means of preventing the spread of...
