Shakerian A, Rahimi E, Dehkordi FS., Identification and characterization of resistant Arcobacter isolated from meat products, Onl J Vet Res., 21(12): 766-776, 2017. Authors describe prevalence, virulence genes and antibiotic resistance of Arcobacter species isolated from meat products. Samples were cultured and results confirmed by PCR. Disk diffusion was done to determine antimicrobial resistance. Of 340 samples, 47 (13.82%) were positive for Arcobacter with A. butzleri 10.29% and A. skirrowii 0.08%. Minced meat was contaminated in 33.4% samples but nuggets and sausage were free from Arcobacter. The most common virulence factors in Arcobacter spp were cadF, ciaB, mviN and pldA and least, hecA and hecB. We found high antibiotic resistance to tetracycline (100%), ampicillin (100%), penicillin (91.48%), gentamycin (85.10%), erythromycin (80.85%), streptomycin (74.46%), clindomycin (57.44%), ciprofloxacin (57.44%), methicillin (55.31%) and chloramphenicol (51.06%).
