Argentine scientists have discovered a fungus capable of destroying mosquito larvae transmit dengue and chikungunya. They hope to convert it into "biological insecticide."
It is a hope in the fight against the epidemic of dengue and chikungunya. Scientists at the National University of La Plata, near Buenos Aires, reported having discovered a deadly fungus to larvae of fifteen varieties of mosquitoes, including those that spread the virus chikungunya and dengue.
In their work, the ten researchers say the fungus (Leptolegnia chapmanii) can develop in different environments, in pure water or soiled, whatever the temperature. And for a small fee, they specify.
Soon a "biological insecticide scale"?
The goal now is to develop a liquid or tablet that "could be introduced into the water for the fungus develops and eliminates larvae" explained Thursday research director, Juan Guarcia. Converted "in biological Insecticide large scale ", the fungus would control the spread of viruses.
Several methods are developed to fight against these diseases. In Guyana, where 881 cases of dengue were recorded in late July, the state has authorized the use of "notwithstanding" malathion, an insecticide banned in Europe in the fight against the disease. Dengue fever, also known as "tropical flu," has spread dramatically in the past of decades as World Health Organizations (WHO).
Currently there is no approved vaccine against these diseases. American researchers have however made a first clinical vaccine against chikungunya which has proved very promising trial. Present in southern Europe since the mid-2000s, the virus is poised to expand in the Americas.
