Antibiotic Resistance and Plasmid Profiles of Vibrio Isolates from Cultured Silver Sea Bream, Sparus sarba

摘要

A total of 51 potential pathogenic vibrios were isolated frommoribund silver sea bream (Sparus sarba) collected from fish farms inHong Kong. Using the API 20E system and the scheme of Alsina andBlanch (1994), 7 speices were identified fromall isolates. Thesespecies were Vibrio alginolyticus (24 strains), Vibrio vulnificus (12strains), Vibrio parahaemolyticus (7 strians), Vibrio logei (4strains), Vibrio pelagius II (2 strains), Vibrio fluvialis (1 strain)and Vibrio meditterranei (1 strain). The three dominant species (V.Alginolyticus, V. Vulnificus and V. parahaemolyticus) were confirmedto be virulent to sea Bream by experimental challenge.
