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

Taxonomy

The following three species are assigned to the genus: [2]

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]

Phikmvvirus is a genus of viruses that infect bacteria. There are currently 16 species in this genus including the type species Pseudomonas virus phiKMV. Bacteriophage phiKMV and its relatives are known to be highly virulent phages, producing large clear plaques on a susceptible host. The only reported exception is phage LKA1, which yields small plaques surrounded by a halo. While all other P. aeruginosa-specific phikmvviruses use the Type IV pili as primary receptor, LKA1 particles attach to the bacterial lipopolysaccharide layer.
