The tripartite interactions between the mosquito, its microbiota and Plasmodium

Area of Science:

• Vector biology
• Microbiology
• Malariology

Background:

• The mosquito microbiota significantly impacts Anopheles mosquito infection by Plasmodium parasites.
• This interaction influences mosquito fitness and vectorial capacity, presenting a natural barrier to malaria transmission.
• Recent research has focused on the complex interplay between mosquitoes, their microbiota, and Plasmodium.

Purpose of the Study:

• To review the effects of mosquito microbiota on Plasmodium infection and mosquito physiology.
• To discuss how these interactions influence malaria vectorial capacity.
• To highlight current challenges and future research directions in the field.

Main Methods:

• Literature review of recent functional characterization studies.
• Synthesis of findings on tripartite interactions (mosquito-microbiota-Plasmodium).
• Discussion of experimental and methodological challenges.

Main Results:

• Mosquito microbiota can inhibit Plasmodium infection and affect mosquito fitness.
• The composition of the mosquito microbiota is crucial for its impact on vectorial capacity.
• Significant progress has been made in understanding these functional interactions.

Conclusions:

• The mosquito microbiota represents a promising target for novel malaria transmission-blocking strategies.
• Further research is needed to address challenges in microbiota composition, non-bacterial microbiota characterization, and extra-gut microbiota studies.
• A deeper understanding of these interactions is essential for developing effective malaria control measures.
