Senftenberg) is one of the most common serovars isolated from various animals and humans. According to the White\u2013Kauffmann\u2013Le Minor scheme, its antigenic formula is defined as 1,3,19:g,[s],t:\u2013, whereas 1,3,19:z27:\u2013 was formerly designated as serovar Simsbury but later excluded due to interconvertibility with Senftenberg. The H:z27 antigen is now recognized as an R-phase H antigen of S. Senftenberg. To clarify the genetic basis of H:z27 expression, we determined whole-genome sequences of H:z27-expressing isolates. These isolates belonged to sequence type (ST) 185 and harbored a horizontally acquired chromosomal locus containing fljB and fljA homologues, predicted to encode a flagellin and a translational repressor of fliC mRNA, respectively. Deletion of this locus resulted in expression of the H:g,s,t antigen instead of H:z27, as confirmed by serotyping and Western blot analysis. Bayesian temporal phylogenetic analysis suggested that the ST185 lineage acquired this locus around 1871 (95% highest posterior density: 1785\u20131934).<\/jats:p>","DOI":"10.1093\/femsle\/fnag076","type":"journal-article","created":{"date-parts":[[2026,7,2]],"date-time":"2026-07-02T11:35:03Z","timestamp":1782992103000},"source":"Crossref","is-referenced-by-count":0,"title":["Genetic
