Mosquito Microbiome Interactions
Project Lead(s)
Senior Research Fellow
Project Background
Disease transmission blocking is an expanding area of vector-borne disease research which seeks to understand the mechanisms that disrupt the development and limit the transmission of parasite from vector to human host. Some micro-organisms associated with mosquitoes demonstrate anti-parasitic effects independent of the mosquito immune system. Understanding this mechanism could help propose bacteria-mediated strategies for vector and disease control.
Objectives/Research Areas
Research in the MoziBiome lab focuses on:
- clarifying the mechanisms involved in the inter-relationship between mosquito microbiota and mosquito-borne parasites,
- characterising mosquito-associated micro-organisms (bacteria, fungi, viruses, protists) of mosquitoes to identify the most effective combination of these for pathogen transmission-blocking,
- understanding bionomics and acquisition of microbes by mosquito vectors for novel disease control approaches,
- how micro-organisms influence variations in vector competence in natural mosquito populations.
