# SISTR SISTR (*Salmonella In Silico* Typing Resource) produces serovar predictions from whole-genome sequence assemblies by determination of antigen gene and cgMLST gene alleles using BLAST. Pathogenwatch uses the `cgmlst_subspecies` and `serovar` fields from the JSON output. is used as a base image. ### How to cite Yoshida CE, Kruczkiewicz P, Laing CR, et al.
