The occurrence of Vibrios spp., which have been related with several infections in both<br />

humans and animals are known to be influenced by a high environmental temperature<br />

and high salinity of water. In this study, samples of water, seagrasses and sediments<br />

were taken from three different stations that consist of seagrasses bed from the<br />

species of Halodule pinifolia which is placed in Setiu Wetland Terengganu for detecting<br />

the presence of Vibrio spp. and to observe the trend of occurrences of Vibrio spp. in<br />

three of the studied stations. Among the three samples tested (water, sediments and<br />

seagrasses), the highest amount of the bacteria count is obtain from sediments which<br />

is 5.038CFU/g compared to water (2.752CFU/ml) and seagrasses (3.113CFU/g)<br />

respectively. While the detection and identification of Vibrio spp. was done by using<br />

Vitek 2 System (bioMérieux, Inc.). The results obtained were Photobacterium<br />

damselae with 99% probability, Aeromonas salominicida (93%) and Esherichia coli<br />

(86%) probability. Nevertheless, Vitek 2 has problems to identify and determine<br />

susceptibilities of some Vibrio species.<br />
