In the next SISTR release check serogroup predictions. In version 1.1.1 the predicted O9,46 antigen was reported as D1 serogroup instead of expected D2 for PulseNet sampleID 21-01676. Not critical, but need to check the cause of this serogroup misassignment.
The Salmonella O antigens belonging to serogroups O2 (A), O4 (B), O8 (C2–C3), O9 (D1), O9,46 (D2), O9,46,27 (D3), O3,10 (E1–E3), and O1,3,19 (E4) form a distinct set that is characterized by having a Gal residue as the first sugar of the O unit and a wbaP gene in the O-antigen gene cluster
In the next SISTR release check serogroup predictions. In version 1.1.1 the predicted O9,46 antigen was reported as D1 serogroup instead of expected D2 for PulseNet sampleID 21-01676. Not critical, but need to check the cause of this serogroup misassignment.
