Family: Inoviridae

Genus: Tertilicivirus


Distinguishing features

Virions of Pseudomonas phage Pf3 are about 700 nm long and 7 nm wide and adhere to the conjugative RP4 pili of Pseudomonas aeruginosa. The phage genome is 5,833 nt long, encodes 9 proteins and persists extra-chromosomally in the bacterial host (Newman et al., 1982, Luiten et al., 1985).
