Complete Genome Sequence of Bacteriophage EFC1 Infecting Enterococcus Faecalis From Chicken

Abstract In response to Enterococcus faecalis infection of chicken origin, a multi host lytic phage, EFC1 was isolated and characterized the double-stranded circular DNA genome with size of 56099 bp, containing 89 predicted protein coding genes as well as 2 tRNAs involved in intron, structure, transcription, packaging, DNA replication, modification, lysis. Observation of the structure by electron microscopy and comparative phylogenetic analysis of terminase large subunit showed that the phage EFC1 belongs to a new member of Siphoviridae, which is relatively distantly related to its high similarity phages. The phage EFC1 has no relevant virulence genes and antibiotic resistance genes.
