Type Species

00.037.0.01.001.     Enterobacteria phage MS2

List of Species Demarcation Criteria in the Genus

A major difference between members of the species Enterobacteria phage MS2 and Enterobacteria phage BZ13 (formerly called subgroups I and II) is a ~60 nt deletion in the 3'UTR of members of Enterobacteria phage BZ13, comprising three small RNA hairpins. There is also a 35 nt deletion in the replicase gene of members of Enterobacteria phage BZ13 producing a shorter hairpin stem. Furthermore, the percentage of as or nt sequence identity is dramatically lower between the two species than between strains within a species. Species can also be distinguished by serological means and by species-specific antisense DNA probes.

List of Species Demarcation Criteria in the Genus

The major difference between Enterobacteria phage Qβ and Enterobacteria phage F1 (formerly called subgroups III and IV respectively) is a ~90-nt deletion in the maturation-protein gene of (Qβ). corresponding to a bifurcated hairpin. There is also the extra stem-loop (V1) in the 3'UTR of members of Enterobacteria phage Qβ that is lacking in members of Enterobacteria phage F1. Species can also be differentiated by serological criteria and by species-specific antisense DNA probes. Finally, the percentage of as or nt sequence identity is dramatically lower between the two species than between strains within a species.
