Bruynoghevirus

Bruynoghevirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts. There are currently seven species in this genus, including the type species Pseudomonas virus LUZ24.[1][2]

Structure

Viruses in Bruynoghevirus are non-enveloped, with an icosahedral head (63 nm) and a short tail (12x8 nm).[1] Although these phages produce small and turbid plaques, all attempts to isolate stable lysogenic P. aeruginosa clones failed. In addition, their genome (around 45kb) does not encode obvious genes indicative of lysogeny.[3] Genomes are linear, around 45kb 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]
