This is the authors' abstract. We don't add key points for this paper.

Fowl typhoid (FT) is a concerning poultry disease caused by S. Gallinarum.Five S. Gallinarum lineages (I to V) were demonstrated in South American farms.S. Gallinarum lineages have specific antimicrobial resistance / virulence genomic profiles.Main FT outbreaks in Brazil have been caused by the specific lineage II.
