frostyj Posted July 16, 2010 Share Posted July 16, 2010 THURSDAY, July 15 (HealthDay News) -- In what might someday be a major advance against one of the world's most devastating diseases, researchers say they've created a mosquito that is unable to infect humans with malaria. The University of Arizona team reported that their genetically altered mosquitoes are immune to the malaria-causing parasite, a single-cell organism called Plasmodium. The mosquitoes used in the research were Anopheles stephensi, a species that plays a major role in malaria transmission throughout the Indian subcontinent. It may be possible someday to replace wild mosquitoes with lab-bred mosquitoes that can't infect humans with malaria, researchers said. "If you want to effectively stop the spreading of the malaria parasite, you need mosquitoes that are no less than 100 percent resistant to it. If a single parasite slips through and infects a human, the whole approach will be doomed to fail," research leader and entomology professor Michael Riehle said in a university news release. He and his colleagues tested their genetically-altered mosquitoes by feeding them malaria-infested blood. Not a single mosquito became infected with the malaria parasite. "We were surprised at how well this works. We were just hoping to see some effect on the mosquitoes' growth rate, lifespan or their susceptibility to the parasite, but it was great to see that our construct blocked the infection process completely," Riehle said. Each year, about 250 million people worldwide contract malaria and about one million die, most of them children. The study appears July 15 in the journal PLoS Pathogens.

Burgundy Burner Posted July 16, 2010 Share Posted July 16, 2010 Now, if they can create one that sucks fat instead of blood, then we're talking! Link to comment Share on other sites More sharing options...
Madison Redskin Posted July 16, 2010 Share Posted July 16, 2010 So we are going to have mosquitos that can transmit malaria and mosquitos that can't transmit malaria. Awesome. Link to comment Share on other sites More sharing options...
Elessar78 Posted July 16, 2010 Share Posted July 16, 2010 Man, there's a huge alarm bell going off above a sign that says "law of unintended consequences" hey great for science that they got this far, but really let's fix it from a vaccine/human immunity standpoint and not by releasing an organism that mother nature never intended into the environment.

GhostofSparta Posted July 16, 2010 Share Posted July 16, 2010 I'd rather eliminate mosquitos. Sure, that would screw up the eco-system, but so might bio-engineering a completely new breed of mosquito. If that's the case, I'd rather err of on the side of a world without mosquitos.

Destino Posted July 16, 2010 Share Posted July 16, 2010 What could go wrong? lol Add me to the "no thanks" on the man made bugs. Especially when dealing with short life spans that can potentially evolve new changes quickly. Link to comment Share on other sites More sharing options...
Unforgiven Posted July 16, 2010 Share Posted July 16, 2010 Every time I read a story like this, my hope that we'll survive long enough to colonize other planets dies a little bit. Maybe us being stuck on Earth and never spreading out is for the best. Seriously? You're gonna genetically mutate an ancient insect that carries a disease that's been around hundreds of thousands of years and think no harm could come from this?

Here's a thought on genetically engineered insects. Killer Bees. Link to comment Share on other sites More sharing options...
Elessar78 Posted July 16, 2010 Share Posted July 16, 2010 Killer Bees. I don't see what the Wu Tang Clan has to do with any of this. Link to comment Share on other sites More sharing options...
frostyj Posted July 16, 2010 Author Share Posted July 16, 2010 I really don't see why this would be a bad thing. Just about everything we eat, drink touch is not how mother nature intended. Man made vaccine's and meds to boost our immune systems are not natural. How is this any different? Link to comment Share on other sites More sharing options...
SkinInsite Posted July 16, 2010 Share Posted July 16, 2010 These things will probably mutate and start the Zombie Apocalypse. Link to comment Share on other sites More sharing options...
PeterMP Posted July 16, 2010 Share Posted July 16, 2010 Come on people. They are mosquitoes. If there is evolutionary worse thing for humans than mosquitoes carrying maliara that is a benefit for mosquitoes, it is likely that mosquitoes would have already found it. These mosquitoes won't be able to mutate into anything that current wild mosquitoes are able to mutate into. There already are mosquitoes that don't carry malaria, and they didn't turn into mutant zombie causing mosquitoes. Link to comment Share on other sites More sharing options...
