Sea turtles are the ancient marine reptiles that have a very important role in our
marine environment. There are many causes of the declination of their population
including diseases. Diseases come from three factors which are toxicological,
physiologic and microbial etiologies. Microbial organisms have been attributed to lower
hatching success of the juveniles, which may leads to the population decrease. The
objectives of this study are; 1) to determine the composition of bacteria and 2) to
identify the types of bacteria that present in the cloacal mucus of green sea turtles.
The results obtained reveals the present of six different bacteria strains. Four of them
were successfully identified through 16s rRNA, which are Ochrobactrum intermedium
(Strain T1), Pseudochrobactrum lubricantis (Strain T2), Klebsiella variicola (Strain T4)
and Shewanella upenei (Strain T6). O. intermedium shows the highest colony count
in all samples and the least is the unidentified species, Strain T3.
