Bacterial strains used and results of phage propagation as detected by a standard lysis procedure and by the described qPCR assay.

Notes: Phage propagation was performed at 28°C unless it is specifically indicated in the column “φA1122 Growth/qPCR”.*Serovars of Y. pseudotuberculosis and Y. enterocolitica are shown in parentheses if known.**On Y. pseudotuberculosis IB, a very weak propagation of φA1122 was observed at 24°C, six orders of magnitude lower than in Y. pestis CO92.
