Strain-specific tracing of bacterial transmission events. The heat map reports in red, purple, and blue the successful strain-specific identification of genomes assembled from shotgun metagenomics data by means of PCR, SNP profiling or PCR and SNP profiling, respectively. Presence of these strains was tested in the CF, LIT, MIL, and PC matrices sampled from the same cheese production site where they were identified. The production site is reported on the right side of the heat map. The table reports genes involved in utilization of milk-related carbohydrates predicted in the partial genomes of the traced strains. Source data are provided as a Source Data file
