Using Microbes as Mosquito Repellents
Researchers have discovered that certain chemicals produced by microbes on human skin can either attract or repel mosquitoes. By manipulating the skin's microbiome, it may be possible to make individuals less attractive to mosquitoes. Experiments with engineered bacteria that produce lower levels of a specific chemical showed promising results in reducing attractiveness to mosquitoes, paving the way for potential long-lasting, living mosquito repellents.
