On the other hand, the Myoviridae phages (P-1, P-2, and P-5) had a slightly longer latent period of 20-30 min.
 observed that Myoviridae phages drastically lost phage activity (3.5 logs PFU [mL.sup.-1]) after 60 min of incubation at 60[degrees]C.
The average burst size of tested phages was about 329 phages per infected cell, which is more than the typical range of 50-100 PFU [cell.sup.-1] for many Myoviridae and Siphoviridae phages [77, 78].
Phage characterization shows that it belongs to family Myoviridae which not only efficiently lyses VRE but also has outstanding thermal and pH stability that makes it a potential candidate for antibacterial therapy.
