A study was conducted to determine the prevalence of Vibrio species in seawater
samples obtained from the coast of Malacca, Penang (Batu Feringgi , George
Town), and Terengganu, respectively.
Four Vibrio cholerae 0139, 10 V. cholerae non-O1, 7 V. cholerae O1 , 160 Vibrio
parahaemolyticus, and 57 Vibrio vulnificus strains were isolated from 240 seawater
samples 4/32 (0.13%), 3/32 (0 09%), 2/32 (0.06%), and 24/32 (0.75%) seawater
samples obtained from Malacca were positive for V. cholerae O 139, V. cholerae
non-O1, V. cholerae O1 , and V. parahaemolyticus strains, respectively. 6/30 and
7/30 seawater samples obtained from Batu Feringgi and George Town beaches
were positive for V. parahaemolyticus, strains, respectively. All the
V. parahaemolyticus strains were Kanagawa-negative. Fifty seven V. vulnificus
strains of biotype 1 were isolated from II ( 18.33%) of 60 seawater samples obtained around Marang beach (Terengganu). The antibiotic resistance patterns of
all Vibrio species strains tested showed that all were resistant to one or more of the
antibiotics tested
