resistance genes

Geneticists discover that insecticide resistance genes work together in mosquitoes, increasing their survival rate with important consequences for pest management.

Mosquitoes harboring two insecticide-resistance genes have been found to survive unexpectedly well in an insecticide-free environment where carrying such genes would normally expected to be a burden.

This results from the genes interacting with one another to the advantage of the host and to the detriment of pest management strategies affecting human health.

Drug resistant hospital superbugs like MRSA have been kept under control in Denmark for more than 30 years.

But the latest reports say that in the last 10 years MRSA cases have risen 10 times as new strains of bacteria with resistance genes spread through the community.
