Uetakevirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts. There are currently three species in this genus, including the type species Salmonella virus Epsilon15.[1][2] These phages are temperate and infect Salmonella (Salmonella virus Epsilon15) and Escherichia coli (Escherichia phage PhiV10).

Structure

Viruses in Uetakevirus are non-enveloped, with icosahedral and Head-tail geometries, and T=7 symmetry. The diameter is around 70 nm with a short tail of about 15 nm and tailspikes surrounding an external tail hub.[1] The genomes of these phages are linear double stranded DNA (~40kilobases), terminally redundant and circularly permuted. Transcriptional units separate the genome in an early and a late region, one on the negative strand (regulation and recombination) and the one on the positive strand (packaging, morphogenesis, lysis and integration).[3] Genomes are around 40kb in length.[1]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. Dna templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion. [1]
