^aPhage ϕJA1 isolated from sewage lyses multiple Y. pestis strains but not Y. pseudotuberculosis or E. coli K-12; it has some degree of homology to L-413C because its DNA is amplified in qPCR with one of two tested pairs of primers specific for L-413C (A.A. Filippov, Y. He, and K.V. Sergueev, unpublished data).

^dNA, not applicable.

^eT7_Yp is a T7 host range mutant isolated on the lawn of Y. pestis CO92; T7_Yp produces plaques on Y. pestis but not on Y. pseudotuberculosis or Yersinia enterocolitica and has a low plaquing efficiency on E. coli K-12 (A.A. Filippov, Y. He, and K.V. Sergueev, unpublished data).

^hR phage (R stands for “Russian” [12]) was originally isolated and studied by R.I. Kotlyarova [64] and is also designated as the Kotlyarova phage. Pseudotuberculosis diagnostic phages PST [63] and R [15] can lyse 92–100% of Y. pseudotuberculosis strains but are also active against the majority of Y. pestis strains.
