The bacteria in the mosquito’s gut raises hope

in 2021, Malaria killed 619,000 peopleMost of them are on the African continent. New prospects for effective control of this mosquito-borne disease Raise high hopes. The optimism is now carried by a multinational team of researchers from the Johns Hopkins Bloomberg School of Public Health in Baltimore and the British laboratory GSK. These reports the worldThey discover a toxin from a bacterium that is able to stop the parasite’s development falciparumresponsible for malaria.

It’s bacteria Delphia tsorohatensis TC1 who is at the heart of all hopes. It is present in many plants as well as in the tissues and organs of some mammals, and produces a toxin that prevents the parasite from developing at an early stage. falciparum in the digestive system of mosquitoes, the researchers explain in an article published August 3 in the journal science.

However, this toxin has the ability to pass through mosquito tissues. So much so that one could imagine spraying a product based on Delftia tsuruhatensis TC1 onto surfaces like mosquito nets. Promising trials have already been carried out in Burkina Faso.

‘Real hopes as battle against disease stagnates’

“This is a major discovery that could direct the fight towards eradicating the disease,” says Pierre Bovet, the institute’s medical director. […] read more
