title: Restriction mediated by pAV2 affects the transfer of plasmids in Acinetobacter calcoaceticus.
abstract: The naturally occurring plasmid pAV2 restricts the entry of the P class plasmid RP4 and the W class plasmids R388 and S-a into Acinetobacter calcoaceticus strain EBF65/65 from Escherichia coli. The W class plasmids only transfer from E. coli into pAV2-strains. Plasmid RP4 is modified in the presence of pAV2 such that it is no longer restricted on entry into pAV2 recipients of strain EBF65/65.
