Distribution of individual genes was analyzed by a Fisher exact test and P < 0.05 was considered significant. Only isolates from dairy foods were considered. Results of poultry food isolate VE14510, stool isolate VE14571 and type strain were not included.
Gene was detected only in reference strains V583 and/or MMH594 meaning it was not detected in the type strain, the stool isolate VE14571 and the food isolate VE14510.
This difference (P = 0.0574) was close to the significance level.
Genes EF1876 and EF1877 were detected in the type strain.
Genes PAIEFxxxx correspond to EFxxxx genes in PAI of strain MMH594 (53).
