Approche combinée d’analyses de séries temporelles et génomiques / exemple de la détection d’une augmentation de la présence de Salmonella Goldcoast en filière avicole

Abstract : Combined approach of time series and genomic analyses: example of the detection of an increase in the occurrence of Salmonella Goldcoast in the French poultry sector Salmonella, an ubiquitous bacteria, is the second-most frequent cause of bacterial food poisoning in France as well as in Europe. In this context, ANSES monitors the food chain via the Salmonella network, which has been centralizing serotyping results for non-human Salmonella for more than 20 years. A statistical tool for time series analysis has been developed for these data, enabling the early detection of unusual increases in specific serotypes at the national or regional level, or in a given sector. Coupling this statistical approach with the genomic analysis of strains makes it possible for these events to be characterized with a very high degree of precision. This article describes an example of this combined approach used for an unusual increase in Salmonella Goldcoast during the 2018-2019 period in France.
