Complete genome sequence of the novel lytic avian pathogenic coliphage NJ01

Bacteriophages of the C3 morphotype, characterized by very long heads that exceed their width several times, are extremely rare among the Podoviridae family members and constitute only 0.5% of over 5,500 phages that have been examined by the electron microscope (H. W. Ackermann, Arch. Virol. 152:227-243, 2007; H. W. Ackermann, Arch. Virol. 146:843-857, 2001). To date, among those phages proven to be C3, only coliphage phiEco32, Lactococcus phage KSY1, Vibrio phage 71A-6, and Salmonella enterica phage 7-11, but no avian pathogenic Escherichia coli (APEC) bacteriophages, have been completely sequenced (A. Chopin, H. Deveau, S. D. Ehrlich, S. Moineau, and M. C. Chopin, Virology 365:1-9, 2007; S. A. Khan, et al., Mol. Cell Probes 15:61-69, 2001; A. M. Kropinski, E. J. Lingohr, H. W. Ackermann, Arch. Virol. 156:149-151, 2011; D. Savalia, et al., J. Mol. Biol. 377:774-789, 2008) and are available in public databases. We isolated a bacteriophage from a scale duck market in Nanjing, Jiangsu province, named NJ01, that infects APEC. Sequence and morphological analyses revealed that phage NJ01 is a C3-like bacteriophage and belongs to the Podoviridae family. Here, we announce the complete genome sequence of phage NJ01 and submit the results of our analysis.
