Isolation and identification of Vibrio spp. from common Geloina (Polymesoda expansa) from Gong Batu, Setiu, Terengganu

Abstract

Twelve isolates were successfully isolated from Common Geloina (Polymesoda expansa) at Gong Batu, Setiu, Terengganu. They were identified as Vibrio a/gino/yticus (25 % ), Vibrio harveyi (16. 7 % ), Vibrio parahaemo/yticus ( 41. 7 % ), and Vibrio fluvialis (16.7 %) by using morphological, biochemical and physiological tests. Iso]ates were primarily selected based on their color on TCBS agar after 24 hours incubation. The identification also was done using reference isolates from Bergey' s Manual and Alsina' s Keys. Moreover, numerical analysis was done to get percentage of similarity among isolates as well as similarity isolates forming dendrogram among the isolates. Results indicated a significant presence of potentially pathogenic of Vibrio species along Terengganu and it shows that (;ommon Geloina (Polymesoda expansa) as important carrier of Vibrio species.
