A newly identified virulent Cronobacter sakazakii phage, ESSI-2, was isolated from fecal samples from swine. The morphological characteristics evident under a transmission electron microscope indicated that phage ESSI-2 belonged to the family Myoviridae. The genome of phage ESSI-2 comprised a double-stranded DNA of 28,765 bp with a G+C content of 55. 17%. Bioinformatic analysis of the phage genome identified 36 putative open reading frames (ORFs). The genome of phage ESSI-2 was not significantly similar to that of a previously reported bacteriophage of the members of Enterobacteriaceae. A lysogeny module was found within the genome of this virulent phage.
