Uncommon Salmonella Infantis Variants with Incomplete Antigenic Formula in the Poultry Food Chain, Italy

Emerg Infect Dis. 2024 Apr;30(4):795-799. doi: 10.3201/eid3004.231074.ABSTRACTUncommon Salmonella Infantis variants displaying only flagellar antigens phenotypically showed identical incomplete antigenic formula but differed by molecular serotyping. Although most formed rough colonies, all shared antimicrobial resistances and the presence of usg gene with wild-type Salmonella Infantis. Moreover, they were undistinguishable wild-type Salmonella Infantis by whole-genome sequencing.PMID:38526241 | DOI:10.3201/eid3004.231074
