Mathematical Modelling of the Dynamics and Control of Salmonella

The Pig Site – Key findings are outlined from a research project carried out at the University of Liverpool which was funded by the Biotechnology and Biological Sciences Research Council and BPEX, as part of a Collaborative Award in Science and Engineering (CASE) studentship.
The aim of the research was to develop mathematical models to understand the dynamics of Salmonella transmission on finishing pig farms in the UK and assess whether farm structure has any effect on this. The aim was to use these models to investigate where control strategies should be aimed.
Two key forms of unit structure (fully slatted and solid floor) were analysed and three models describing Salmonella transmission were developed:
  • Single room, fully-slatted floor
  • Multiple rooms, fully-slatted floor
  • Single room, solid floor
The models identified some key results with regard to on-farm Salmonella dynamics.
A principal finding showed that there is not a single action that can solve the problem but rather, a number of aspects should be targeted… Continue Reading
