Brazil begins testing a new way to prevent disease transmission.
With this news, the mosquito Aedes aegypti, which was enemy turned ally.
The Brazil began testing on Wednesday (24) a new way to prevent dengue transmission. With this news, the mosquito Aedes aegypti, which was enemy turned ally.
The pots full of mosquitoes Aedes aegypti were opened in the middle of the street Tubiacanga, on Governor's Island, the North Zone of Rio de Janeiro.
But these mosquitoes are prepared in the laboratories of Fiocruz. Females carry a bacterium called Wolbachia, which blocks the transmission of dengue virus.
The bacterium is present in 60% of the insects in the world, but the Aedes aegypti and has needed for a force of science.
Researchers from Australia were the first to collect the Wolbachia from fruit flies and inject eggs of dengue mosquitoes. In this experiment, the majority of born larvae with bacteria. Then, adult mosquitoes were released in the wild in Australia, Vietnam and Indonesia.
"At 15 weeks after the start of releases of mosquitoes, the number of mosquitoes capable of transmitting dengue reduced by over 80%," says Fiocruz researcher Rafael Freitas.
Tubiacanga, with high dengue incidence, was the first in the Americas to receive the mosquitoes.
"If the dengue mosquito was now the enemy that Wolbachia is a mosquito friend," said the nurse Maria Inês Silva Barros.
This gesture of releasing 10 000 mosquitoes in nature will be repeated once a week for the next three to four months in Tubiacanga. During this period, the eggs and larvae of these insects will be monitored and analyzed in the laboratory to see if they are born with the bacteria. The forecast is that by the end of the year has already been a good result.
"We hope that maybe next season of dengue we already have a reduction of local cases. Working, we can make the expansion of this project for the country, "says the Fiocruz researcher Luciano Moreira.
Residents help researchers collect the eggs in the traps. But we also know that they must keep doing homework and keeping everywhere without standing water.
"One should not, at any moment, imagine that because we have new mechanisms of control we will reduce accountability and public participation in dengue control," says the President of Fiocruz, Paulo Gadelha.
