Sampling from the water was conducted within 4 seasons. Arcobacter spp. was isolated using standard method then identified by Phenotyping tests. Finally, the identification of strain was verified by PCR method. After conducting of the Phenotyping methods and their authentication with molecular technique, fourteen strains of Arcobacter butzleri were identified. With regard to the obtained results, prevalence of this bacterium in the coastal waters of the Caspian Sea's was evaluated as 5.32 percent. The result obtained from this study is, in fact, regarded as the first report from the isolation of Arcobacter butzleri from Caspian Sea. Knowledge of the state of the entry and time span of the survival of the Arcobacter in the water environments to control the water quality and prevention from the disease is of importance. http://pubs.sciepub.com/jaem/2/2/5/jaem-2-2-5.pdf Arcobacter butzleri isolation Caspian Sea water sample
