Engineered Skin Microbiome Reduces Mosquito Attraction to Mice

Area of Science:

• Microbiology
• Vector Biology
• Genetic Engineering

Background:

• The skin microbiome significantly influences mosquito attraction through volatile cues.
• L-(+)-lactic acid produced by skin bacteria is a key attractant for mosquitoes.
• Current repellents like DEET offer limited protection duration.

Conclusions:

• Engineering the skin microbiome to reduce attractive volatiles is a viable strategy to mitigate mosquito attraction.
• This approach offers a promising new avenue for developing long-lasting repellent products.
• Reducing vector attraction through microbiome modification can help prevent mosquito bites and pathogen transmission.
