Summary: Microorganisms including commensals and pathogens can live in complex communities in a range of environments including animal hosts. It is now known that these communities (known as microbiomes) can exert a profound effect on animal health. This project seeks (i) to understand where antimicrobial resistance genes reside in pig gut microbiotia and how they move between members of this complex microbial community and (ii) provide information on how probiotics may be utilised to reduce the dependence on antibiotics. The datasets will provide science-based foundation for surveillance and response programs for key biosecurity threats and assist with the development of predictive models for changes in the distribution of drug resistant bacteria.
