The project starts from the concept that the host microbial community (MC) is influenced by the host itself and by the microbial community of the system in which the host is living. It is anticipated that there is a reciprocal interaction between the different compartments of the system in every stage of the life cycle.

The strength and the nature of those interactions can depend on the life cycle stage. Apart from these horizontal interactions, it is anticipated that microbial communities evolve as the host grows or the system changes. A certain degree of top-down conditioning belongs to the possibilities.

This would mean that the early colonisation of the host by certain micro-organisms, might condition the host response and determine the microbial community composition in later life stages. In addition the environment (e.g. temperature, feed, water quality, sanitation measurements) will determine to a great extent the composition and activity of the microbial communities in the different compartments. The environment can be modulated through the composition of the feed or through compounds that directly influence the activity of micro-organisms. On the other hand nutritional compounds or immunomodulators might have a direct influence on the host, modulating the microbial community of both host and system.
