Evidence for the existence of a restriction-modification system common to several species of the family Vibrionaceae.
A broad-host-range vibriophage KVP40 originally isolated on Vibrio parahaemolyticus 1010 was restricted and modified by strains of at least five Vibrio and one Photobacterium species. 1010 was a non-restricting host. An anti-restriction mutant KVP40 aar1 was isolated after propagating the phage on a restricting host, V. anguillarum VIB36. KVP40 aar1 grown on either 1010 or VIB36, as well as the parental phage grown on VIB36, showed much higher efficiencies of plating on all the restricting hosts as compared with the parental phage grown on 1010, indicating that these restricting hosts probably share a common restriction-modification system active in vivo on KVP40.
