Source attribution modelling of Salmonella Typhimurium and the monophasic variant.

Monophasic Salmonella isolated from UK animals between 2014 and 2016. Sequence data will be used to define meaningful clusters for source attribution in Salmonella typhimurium and monophasic variants. This will help define meaningful clusters for future source attribution and outbreak investigations in Salmonella spp and use this data as inputs to redefine and if possible integrate existing source attribution models including also the approach based on foodborne outbreak data as described by Pires et al. 2012. Novel approaches will be built in a Bayesian framework to combine information on the pathogen (phylogenetic information, plasmid occurrence, virulence, etc.), the source (exposure, prevalence, import-export, etc.) and the human host (consumption, travel history etc.).
