Promising test in Australia to fight dengue fever

Promising trial in Australia to fight dengue fever

Sydney – Over 80% of a mosquito colony killing dengue fever was wiped out in an Australian city under a promising test to combat this dangerous viral infection. Researchers said Tuesday

Scientists from Samvets Scientific and Industrial Research Organization (CSIRO), a public Australian scientific research organization, has reproduced millions of non-biting Aedes aegypti male mosquitoes as part of a funded project. by Alfabet, Google's parent company.

Insects were infected with the bacterium Wolbachia, making them sterile. They were later released in Innisfail, a city in the regional state of Queensland (northeast). For more than three months, they hatched honey that laid eggs that had not hatched, causing a sharp decline in their population.

The mosque Aedes aegypti, one of the most dangerous in the world, is the vector dengue, zika virus, chikungunya and yellow fever. It is responsible for infection of millions of people every year around the world. Therefore, this scientific test is a major breakthrough, "says Kyran Stauton, Australian University James Cook.

"We learned a lot from participating in this first tropical trial and we are pleased to see this method applied to other areas where Aedes aegypti is a threat to life and health," he says.

This insect sterilization technique has previously done, but the challenge of succeeding mosquitos was to be able to produce enough of them to identify the men, to remove the biting women and then release them in numbers that are large enough to wipe out a population.

"We are very happy to see a significant removal of these dangerous biting Aedes aegypti mosquitoes, "said Nigel Snoad, from the Life Science Company Verify (Alphabet), who funded the project.
