Fig. 2From: Oxidative stress, gene expression and histopathology of cultured gilthead sea bream (Sparus aurata) naturally co-infected with Ergasilus sieboldi and Vibrio alginolyticusVibrio alginolyticus virulence genes (collagenase, VptoxR, tdh) using Multiplex PCR. Agarose gel electrophoresis (1.5% agarose) of the collagenase (lanes 1–4) amplification products (738 bp) of V. alginolyticus strains. Lane: M, molecular weight marker. Neither amplification products (296 bp) for VptoxR, nor amplification products (270 bp) for tdh. Lanes 1, 2, 3, and 4 refer to VAK4, VASk3, VAM6, and VASp1 isolates, respectivelyBack to article page
