Antimicrobial susceptibility of Arcobacter butzleri isolated from environmental samples in north of Iran

Introduction: During the past decade Arcobacter has been shown to be responsible for gastrointestinal disease in human and animal. These organisms may enter the environment, including drinking water, through the feces of animals, birds or infected humans. The major purpose of this study was isolation, identification and antimicrobial susceptibility of Arcobacter spp. isolated from river water in north of Iran.Material and Methods: Arcobacter spp. was isolated using standard method then identified by Phenotyping tests. Finally, the identification of strain was verified by PCR technique. Then antimicrobial susceptibility of the isolates against different antibiotics and Minimal Inhibitory Concentration (MIC) values were determined by disc diffusion and E-test respectively.Results: In general, 15 strains of Arcobacter butzleri were isolated. The results obtained indicated that frequency of occurrence of Arcobacter butzleri in environmental sample was high. All strain was resistant to Penicillin G, aztreonam, cephalothin, oxacillin and trimethoprim/sulfamethoxazole. In addition, the lowest values of MIC were found for Azithromycin, while the highest value was found for chloramphenicol.Conclusion: Overall, our observations, illustrated that pathogenic Arcobacter were existed in river water in north of Iran and therefore, the people who living in this area must respect to the personal hygiene in order to avoid from Arcobacter infection.
