The microbes associated with polychaete may produce bioactive compound that also
can give advantage to the polychaete as a host to the microbes. Bacterial infections
is the major health problem worldwide. This study was perfomed to characterize
bacteria and to determine antimicrobial activity produce by bacteria associated with
Marphysa moribidii. The sample of polychaete was taken in Pantai Morib, Selangor.
Biochemical test and Bbl crystal test were utilized to characterize and to identify the
species name of bacteria that associated in Marphysa moribidii. Disk diffusion Kirby-
Bauer method was performed to test the susceptibilty and resistant of isolated bacteria
from gut and surface. The bacterial strain was identified as Corynebacterium
pseudogenitalium and Elizabethkingia meningoseptica for each isolated bacteria. The
antimicrobial activity showed that there is significant difference between gut and
surface. The study of antimicrobial activity need to be continued for further
identification of new antibiotic to against bacteria pathogen.
