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 betwee
