coli Sm10 into V. anguillarum by conjugation. Transconjugants were selected by utilizing the chloramphenicol resistance gene located on the suicide plasmid. The incorporation of the recombinant pNQ705 was confirmed by PCR amplification.

The 5′ region of rtxA was amplified using the primer pair pm256 and pm257 (Table 3), digested with XhoI and XbaI, and then cloned into the region between the XhoI and XbaI sites on pDM4 (GenBank accession no. KC795686), deriving pDM4-rtxA5′. The 3′ region of rtxA was amplified using the primer pair pm258 and pm259 (Table 3), digested with XbaI and SacI, and then cloned into the region between the XbaI and SacI sites on the pDM4-rtxA5′. The resulting pDM4-rtxA5′-rtxA3′ was transformed into E. coli Sm10 to produce the transformant strain S252, which was mated with V. anguillarum S171 (vah1).
