We report sequencing of the O antigen encoded by the rfb gene cluster of Salmonella enterica serotype Jangwani (O17) and Salmonella serotype Cerro (O18). We developed serogroup O17- and O18-specific PCR assays based on rfb gene targets and found them to be sensitive and specific for rapid identification of Salmonella serogroups O17 and O18.
Sequence analysis of the rfb loci, encoding proteins involved in the biosynthesis of the Salmonella enterica O17 and O18 antigens: serogroup-specific identification by PCR.
