Diopatra claparedii lives inside sedentary tube in mangrove and mudflats with medium
tide level. The role of bacteria in terms of pathogenicity, identified from Diopatra
claparedii is not clearly defined yet. The identification of bacteria from D. claparedii is
a new study and need to be explored to enhance importance of bacteria for future
medical diagnostic, industrial purposes and fulfil research needs. The main objective
of this study was to identify bacteria from internal organs of D. claparedii including
muscle, blood and blood vessels. Bacteria were isolated on agar and further identified
using BBL Crystal ID Kit. Results showed that Gram positive bacteria inhabited the
respiratory tract tissue such as muscle, blood and blood vessel and mostly found in
bacillus shape. Bacteria identified are Leifsonia aquatica, Brevibacillus brevis,
Corynebacterium sp, Corynebcaterium pseudogenitalium, and Corynebacterium
propinquum. L. aquatica has the highest confidence which was 0.996, compared to
the other bacteria.
