Identification of Vibrio anguillarum by PCR (rpoN Gene) Associated with Vibriosis in Marine Fish in Turkey

Authors: DİDEM DEMİRCAN, AKIN CANDAN

Abstract: The main causative agent of vibriosis is Vibrio anguillarum. In this study, 33 V. anguillarum strains were isolated from the internal organs of marine fish showing typical clinical signs of vibriosis, and these strains were identified by biochemical tests. For comparison of these results, API 20E and BIONOR Mono-Va agglutination kits were used. Finally strains were amplified by PCR using the rpoN gene. Although the phenotypic properties of V. anguillarum strains varied, the rpoN gene from chromosomal DNA was amplified in all strains. In conclusion, this gene could be used in the diagnosis of V. anguillarum strains isolated in Turkey.
