I draw your attention to a symposium that might be of interest. It is organised in June 2015 in paris (National vet school in Maisons-Alfort). The symposium "Pathobiome: pathogens in microbiotas in hosts" will explore different issues on the impact of microbial interaction within vectors and hosts on the evolutionary dynamics and transmission of pathogens.
The symposium will be held in Paris from 23th to 25th June 2015.
