Isolation and identification of vibrio fluvailis from goldfish Carassius auratus In AL NajafAl-Ashraf Governorate

Abstract

This study aimed to diagnose the Vibrio fluvailis and identify some of the virulence genes, Eighty six samples were obtained from gold fish Carassius auratus which were suffering from infection. Fourty one samples of gold fish Carassius auratus gave a positive result for the Vibrio fluvailis, in percentage ( 47.6%) . The biochemical tests were conducted to confirm the infection as well as the examination of API 20. Polymerase chain technique was used to identify virulence genes hupO that have a role in the pathogenesis of bacteria isolated.
