Identification of Vibrio Spp. from Cultured Seabass Lates Calcarifer and Their Antibiogram Relationship with Plasmid Profiles

Abstract

Thirty eight bacteria isolates were recovered from seabass with vibrios is. These isolates were identified using the convention albiochemical tests and the API - 20E system. Most isolates were cream in colour, round, convex and entire. They were grouped into the genus Vibrio with the following traits: Gram-negative short rods, motile, positive catalase and oxidase reactions, fermentative metabolism towards Hugh and Leifson glucose medium and ferments D-glucose by producing acid but not gas. Yellow colonies (identified as Vibrio alginolyticus) and green colonies (identified as Vibrio parahaemolyticus) were obtained on TCBS agar. The API - 20 E test strips identified fifteen isolates as V. parahaemolyticus and twenty three isolates as V. alginolyticus. Comparative studies between
