Family: Inoviridae

Genus: Villovirus

Distinguishing features

Vibrio phage Vf33 infects Vibrio parahaemolyticus strains expressing the K38 antigen. Virions are about 1,400 nm long and 7 nm wide, with a buoyant density in CsCl of 1.292 g/cm³. Virions are resistant to heating below 80 °C and to treatment with diethylether, acetone or methanol, but sensitive to chloroform. The genome is 8.4 kb long, and encodes 7 proteins (Taniguchi et al., 1984, Chang et al., 1998).
