Viral transmission among bats in the Indian Ocean

This project is structured around two main scientific objectives: (i) the molecular characterization of the diversity of viruses circulating within bat colonies, and (ii) the study of the temporal dynamics of viral transmission within the colonies.

Seasonal environmental changes have major effects on the life cycle of many organisms, influencing factors such as reproduction period, migration, and various other behaviors. The regularity of these events also impacts interactions between hosts and their infectious agents. Bats inhabiting the islands of the southwest Indian Ocean exhibit a highly pronounced seasonal gregarious behavior, forming colonies that are conducive to the transmission of infectious agents. The "colonial living" behavior could represent a major ecological factor in viral transmission mechanisms, and we can hypothesize that this characteristic would have significant effects on the diversity and transmission dynamics of associated viruses.
