Genomic analysis of bacteriophage ESP2949-1, which is virulent for Cronobacter sakazakii

초록

Virulent phage ESP2949-1, which was isolated from sewage, has an icosahedral head, a contractile tail, and a double-stranded DNA genome with a length of 49,116 bp with 50.09% G+C content. Phage ESP2949-1 showed 3% similarity to enterobacteria phage TLS. Bioinformatics analysis of the phage genome revealed 43 putative open reading frames (ORFs). Predicted protein products of the ORFs were determined and described. Based on its morphology, phage ESP2949-1 can be classified as a member of the family Myoviridae. To our knowledge, this is the first report of the genomic sequence and characterization of phage ESP2949-1 isolated from sewage.
