Instead of healing the pots, a new anti-malarial strategy – 27/02/2013

It was developed by a group of scientists from the United States of America A "cure" technique for malaria mosquitoes by eliminating insecticides, according to a study published in Nature on Wednesday. The goal is the same: prevent people from spreading human illness.

Research, directed by the Public Health School T.H. Chan at the Harvard University, showed the drug atovaquoneTo prevent and treat malaria, These insects are also effective.

As humans take their mouths, mosquitoes they suck through the legsWhen they are contacted with the atovaquone surface, for example, in the bed networks.

Experts believe that the mosquitoes treated with this drug were introduced in 2000, He has completely blocked the development of Plasmodium falciparum parasiticThe cause of malaria.

"Elbows are very resistant to organisms They have developed resistance against all insecticides. By eliminating malaria parasites in mosquitoes, we can not kill them effectively preventing them Contagious malaria, "said Flaminia, Catteruccia, immunology teacher and infectious diseases.

In his opinion, the use of mosquito nets helps combat this "destructive disease" "A simple yet innovative idea" "it is safe" for the public and also "respect for the environment".

In the last 20 years, insecticides have been applied to mosquito-resistant applications About 68% of malaria cases have been avoided, some species have recently developed the most common fuels of resistance, known as pirotroids, homes and agriculture.

For this study, scientists have found female Anopheles mosquito mosquitoes responsible for atovaquone compounds, to apply prophylactic abilities to block and develop Plasmodium falciparum parasite.

They found insects he completely abolished the parasite Atovaquone low concentration (100 micrometres per square meter) and six minute exposure, similar to those treated with insecticide bed absorbents.

Experts have similar results with other similar drugs, although underlined by atovaquone, it does not have any effect on life expectancy or mosquito reproductive abilities.

"When we used mechanical data in real world prevalent insecticide resistance, mosquito protection and malaria, an additional use of a compound like atovaquone could reduce malaria transmission to almost malaria. We had data in Africa," said Douglas Paton, chief author of research.
