Phage vB_YenS_P400, a Novel Virulent Siphovirus of Isolated from Deer.

Phage vB_YenS_P400 isolated from deer, is a virulent siphovirus of , whose circularly permutated genome (46,585 bp) is not substantially related to any other phage deposited in public nucleotide databases. vB_YenS_P400 showed a very narrow host range and exclusively lysed two B4/O:3 strains. Moreover, lytic activity by this phage was only discernible at room temperature. Together with the finding that vB_YenS_P400 revealed a long latent period (90 to 100 min) and low burst size (five to ten), it is not suitable for applications but provides insight into the diversity of phages.
