Research project Mechanisms by which pathogens manipulate vector behaviour to enhance transmission

Pathogen renders host more attractive to vector, increasing the risk of its transmission.

The overall purpose and aim of this research proposal is to further analyse the effect of pathogen metabolites on manipulating the human and vector hosts. One specific aim is to clarify why mosquitoes are attracted to infected humans, by increasing our understanding of the volatile compounds induced by pathogen metabolites. Another aim is to assess the effect of the metabolites on the olfactory system of the vector by 1) mapping and modelling the antennal transcriptomes from infected  and infective mosquitoes; and 2) evaluating the behavioural changes mosquitoes exposed to infectious host blood. This will add to my original study, in which a number of novel genes and neural signalling pathways changed expression after infection. The findings of this project may lead to novel ways to decrease mosquito biting, particularly on infective humans, and hence reduce disease transmission.
