The three dsDNA phages tested in this study (isolated on V. parahaemolyticus) 1) infected the same hosts (V. parahaemolyticus, V. anguillarum and A. salmonicida); 2) presented high periods of survival in marine aquaculture water, however, 3) the VP-3 phage showed higher efficiency for the inactivation of V. parahaemolyticus than the VP-1 and VP-2 phages and 4) has a shorter latent period and a higher burst size than the other two phages.
