Figure 1

PCR amplification of the toxR gene (V. parahaemolyticus) and collagenase gene (V. alginolyticus) on agarose gel 1.5%. Lane L: 100-1000 bp. DNA Ladder. Neg.: Negative control (Enterobacteriaceae strain). Pos.: Positive control (local strain obtained from Central Lab. for quality control of poultry production, El-Giza, Egypt (CLQP)) (at 368 bp for toxR gene and 737bp for collagenase gene). Lanes 1-5: V. parahaemolyticus (toxR gene) positive and Lanes 1-5: V. alginolyticus (collagenase gene) negative.
