Isolation and determination of antimicrobial resistance of Arcobacter species isolated from animal faeces in the Diyarbakir region of Turkey using the 16S rDNA-RFLP method

摘要

In this study, the presence of Arcobacter spp. was investigated in the faeces of cattle, sheep, goats, dogs and cloacal swab samples of chickens using the 16S rDNA-RFLP method. The prevalence of Arcobacter in these species was found to be 13%, 12%, 16%, 4% and 33%, respectively. On the other hand, Arcobacter spp. could not be isolated from rabbit faeces. A total of 78 (13%) Arcobacter spp. isolates were obtained from the 500 faecal samples and 100 cloacal swab samples examined in this study. From these 78 Arcobacter isolates, 24 (30.8%), 20.(25.6%), 11 (14.1%), 8 (10.7%), 4 (5.1%), 3 (3.9%) and 2 (2.6%) were identified by 16S rDNA-RLFP as A. cryaerophilus, A..butz- leri, A. skirrowii, A. cloacae, A. cibarius, A. halophilus, and A. nitrofigilis, respectively. All A. cryaerophilus (n.= 24) isolates were found to be resistant to cloxacillin; all A. butzleri (n.= 20) and A. skirrowii isolates were found to be resistant to penicillinovobiocin, cefoperazone, tetracycline and cloxacillin. It was determined in this study that clinically healthy cattle, sheep, goats, dogs and chickens are reservoirs of Arcobacter spp.
