Family: Inoviridae

Genus: Primolicivirus

Distinguishing features

Members of the species Pseudomonas virus Pf1, have virions of about 2,000 × 7 nm (Goldbourt et al., 2010), a genome of 7,349 bases and encode 14 proteins (Hill et al., 1991).  Pseudomonas phage Pf1 was isolated from Pseudomonas aeruginosa strain PAK, adheres to type IV pili and persists extra-chromosomally.
