Epidemiology of Salmonella in poultry: the use of whole genome sequencing to identify points of entry and transmission pathways

Sign up or log in to save this to your schedule and see who's attending!

Current routine surveillance activities for Salmonella spp. in commercial poultry production rely on the use of phenotyping (serotyping and phage typing) tools to determine the entry of Salmonella into populations. The usefulness of MLVA typing (Salmonella Typhimurium) for surveillance beyond outbreak investigation and trace-back to farm have not been substantiated in field studies. The rapid introduction of whole genome sequencing means some of these tools are rapidly becoming unavailable. Despite many years of surveillance and research, we still know very little about the genetic relationships between Salmonella Typhimurium phage types and MLVA profiles and their usefulness in routine field surveillance in commercial production settings. In this study, I compared the use phenotyping (phage typing) and genotyping (MLVA) with whole genome sequencing to understand points of introduction and transmission of Salmonella Typhimurium within two poultry enterprises, egg layer and chicken meat.
