Research Interests

The Bacterial Infection Group (BIG) works on a number of different pathogens and covers many aspects of infection ranging from the nature of the bacteria themselves through to the mechanisms involved in the host recognising and resisting infection. The main bacteria worked on include Salmonella entericaCampylobacter jejuni, bordetellae, veterinary streptococci (especially Streptococcus suis),Staphylococcus aureus and Haemophilus parasuis. We emphasise work leading to an understanding of the host-pathogen relationship, and use techniques ranging from functional genomics to mathematical modelling to try to understand the dynamics of the interactions of bacteria with their hosts. We work at all scales from the molecular to the whole animal, and use tissue-culture cells, in vitro organ culture and whole animal infection models. We are committed to maintaining strong basic research, but do this in the context of finding improved intervention strategies, be they reliant on better husbandry, small-molecule therapeutics, or immunotherapies including vaccination. Our work is as relevant to human infectious disease as it is to infectious diseases of other animals, and we strongly hold the view an approach based on comparative pathology, whereby a natural pathogen is studied in its natural host, is bound to be more productive and useful than studying a human pathogen in a non-natural rodent model.
