Malaria Vaccine Shows Promise in Small Study 2016-05-10T04:00:00Z Dr. Burt said he is also unable to think of any disadvantage to humans or to mosquitoes in eliminating the malaria parasite that preys on both. Gene Drives Offer New Hope Against Diseases and Crop Pests 2015-12-21T05:00:00Z They then teamed up with another research group to create a gene drive that, unleashed in a lab population of mosquitoes, spread genes that prevent the insects from harboring malaria parasites. And Science’s Breakthrough of the Year is … 2015-12-17T05:00:00Z But mosquito-elimination strategies will also be more difficult for malaria parasites to overcome because it would require them to find an entirely new host, he adds. Mosquitoes engineered to pass down genes that would wipe out their species 2015-12-06T05:00:00Z In this way, the host of the malaria parasite should eventually become extinct.

Sickle-Cell May Blunt, Not Stop, Malaria 2011-05-03T17:07:00Z In theory, it should, because Plasmodium falciparum, the malaria parasite, takes about 2 weeks to develop inside the mosquito body, which is most of the insect's lifetime. Antiparasitic Drug Has Bonus Effect on Mosquitoes 2011-07-06T22:40:10Z A team at Harvard University and the Broad Institute in Boston used advanced gene-hunting technology to search the genetic code of the malaria parasite Plasmodium falciparum.

A Fungal 'Vaccine' for Malaria-Carrying Mosquitoes 2011-02-24T19:00:00Z The scientists found the malaria parasites focus on producing cells that replicate quickly to cause infection, rather than cells capable of being taken up by a feeding mosquito and spreading the disease. Malaria parasites use attack plan 2011-02-14T13:15:38Z In West Africa, different populations of the main malaria vector Anopheles gambiae differ in insecticide resistance, climatic tolerance, feeding behavior, and relative resistance to malaria parasites. This Week in Science 2011-02-03T19:25:00.683Z That horrible headache might be a sign of cerebral malaria, a condition in which the malaria parasites burrow into the cerebrospinal fluid that bathes the brain, and sometimes into the brain itself. Malaria on the Rise as East African Climate Heats Up 2011-04-01T18:15:00.220Z Having found the new subtype, the team grew new generations of it in the laboratory and found that it was significantly more susceptible to the malaria parasite than recorded indoor types.

Experts roll out malaria map, urge mosquito study 2010-08-03T21:32:00Z The mosquito is also a sketchy character: of more than 3,000 species, only 70 members of the genus Anopheles transmit malaria parasites. Books: Drama! Intrigue! A Mystery? No, Malaria?s Story 2010-07-26T20:54:00Z Now, using statistical modeling and DNA analysis, a group of researchers report in the journal Science that ancestors of humans first acquired the malaria parasite known as P. falciparum 2.5 million years ago. Observatory: Tracking the Evolution of Malaria 2010-07-19T21:50:00Z The results also showed that even when given low doses of antibiotics, almost all the mice were protected from the fatal brain complications associated with the most dangerous malaria parasite, Plasmodium falciparum. Antibiotics could help control malaria: study 2010-07-14T18:05:00Z Aug. 20, 1897 – Ronald Ross, a British officer in the Indian Medical Service, discovers that malaria parasites can be transmitted through mosquitoes. Malaria's Tenacious Buzz 2010-07-09T22:09:00Z Both the malaria parasite and the mosquitoes which spread it respond to temperature and moisture. Green.view: Don?t sweat it 2010-05-19T13:53:00Z It also aims to limit the spread of malaria parasites that resist treatment in Southeast Asia and the Americas. U.S. effort to fight malaria focuses on women 2010-04-23T02:08:00Z That is echoed by U.S. development agency USAID, which says artemisinin-based combination therapy is "now taking two to three times longer to kill malaria parasites along the Thai-Cambodian border than elsewhere." Cambodia drug-resistant malaria stirs health fears 2010-03-07T00:04:00Z Palace walls could not shield him from the enemy without: the anopheles mosquitoes infesting the Nile Valley with malaria parasites. Malaria: A Scourge as Old as King Tut 2010-02-21T01:21:00Z By the late 1960s, the malaria toll had surged back to over 300 million, only now many malarial mosquitoes were resistant to DDT and malaria parasites inured to the drug chloroquine. Malaria's Tenacious Buzz 2010-07-09T22:09:00Z The team said it isolated DNA of the malaria parasite in several of the family's mummies, including Tut's -- the oldest such discovery. New study explains demise, parentage of King Tut 2010-02-17T05:00:00Z The program will distribute nets and help spray against mosquitoes that carry malaria parasites. U.S. effort to fight malaria focuses on women 2010-04-23T02:08:00Z The team said it isolated DNA of the malaria parasite in several of the family's mummies, including Tut's— he oldest such discovery. 2010-02-16T20:38:00Z Several other mummies in the study also showed DNA evidence for the presence of the malaria parasite Plasmodium falciparum, perhaps not surprising in a place like the Nile Valley. 2010-02-16T17:38:00Z The malarial mosquito and the malaria parasite within it are nothing if not innovative. Malaria's Tenacious Buzz 2010-07-09T22:09:00Z This revealed traces of the malaria parasite in his blood, the Journal of the American Medical Association says. 2010-02-16T16:49:00Z New genetic sampling techniques allowed scientists from France, Cameroon, Gabon and the US to examine evidence of malaria parasites in the faecal matter of wild gorillas and chimpanzees in Cameroon. 2010-01-18T22:53:00Z Previous versions used not AnAPN1 but parts of the malaria parasite to generate human immune responses. 2010-01-15T22:55:00Z The resemblance of the malaria parasite to that of recurrent fever is noted in the work of Sacharoff. Scientific American Supplement, No. 787, January 31, 1891 Bombard billions of malaria parasites with drugs and the creatures will evolve progeny that can withstand them. Malaria's Tenacious Buzz 2010-07-09T22:09:00Z Once Bitten The life cycle of the malaria parasite, Plasmodium. Malaria's Tenacious Buzz 2010-07-09T22:09:00Z And even without that side effect, using antigens from the malaria parasite would require multiple vaccines to fight the many different strains of malaria. 2010-01-15T22:55:00Z
