Genome sequence analysis of Cronobacter phage PF-CE2 and proposal of a new species in the genus Pseudotevenvirus.

The genome of a Cronobacter sakazakii M1 phage named PF-CE2 was characterized in this work, and a new species named "Cronobacter virus PF-CE2", in the genus Pseudotevenvirus of the subfamily Tevenvirinae of the family Myoviridae is proposed. The Gp190 gene of phage PF-CE2 is predicted to encode a bacteriophage-borne glycanase that is capable of degrading fucose-containing exopolysaccharides produced by C. sakazakii M1. Furthermore, we propose changing the taxonomic status of eight additional phages based on nucleotide sequence comparisons. This work provides a theoretical basis for subsequent heterologous expression of the phage PF-CE2 glycanase and provides an important reference for the preservation and sharing of these phages.
