Abstract:
Genus and identification of bacteria species m foods and clinical specimen are
important. In Malaysia, one of the most important bivalve molluscs in aquaculture is
blood cockle (Anadara granosa). The consumption of bivalve molluscs is a major
source of cheap animal protein from marine organisms. However, it is capable of
causing food poisoning outbreak due to Vibrio spp. In the present study, the samples
were bought from Wet Market located in Batu Enam, Kuala Terengganu.
Conventional tests such as morphological, biochemical and physiological tests were
used to identify the green colonies Vibrio spp. on TCBS agar isolated from cockles
(A. granosa). Beside, by using software NTSYS pc version 2.1, the numerical
taxonomy was also used to cluster the Vibrio spp. They were compared with refer
database of two green colonies Vibrio species which were V parahaemolyticus and
V vulnifzcus. Here the isolates were identified as V parahaemolyticus due to the
similarity obtained from the numerical analysis was ranged from 76.92% to 88.89%.
Isolate 6 having the lowest percentage of similarity while the highest similarity was
isolate 3. The vibrios contents in blood cockles were in high amount ranged from p
arahaemolyticus isolates were detected where, 8 isolates showing �-haemolysis and
3 isolates were a-haemolysis on blood agar.
