Campylobacter spp. is recognized as one of the most common pathogens involved in the development of gastrointestinal infections in humans. The current study aimed to enhance the knowledge on the occurrence and molecular characterization of Campylobacter spp. in pigs and cattle origin caecum samples (n = 56) collected in one year, from nine Romanian slaughterhouses, and to determine the antimicrobial resistance profile of the isolated strains. All Campylobacter spp. strains (n = 41) isolated from swine and cattle caecum samples were analyzed in terms of antimicrobial resistance, in accordance with the EURL protocol and with the Commission Implementing Decision No. 2020/1729. The prevalence rate for C. coli. in pig caecum samples was 92.3% (36/39), and the prevalence of C. jejuni, in cattle origin samples was 29.4% (5/17). C. coli strains isolated from pigs proved resistant to tetracycline 75% (27/36), ciprofloxacin 69.4% (25/36), erythromycin 8.3% (3/36), ertapenem 2.8% (1/36) and gentamicin 2.8% (1/36), but no resistance was observed towards chloramphenicol. C. jejuni strains originating from cattle expressed resistance to ciprofloxacin 60.0% (3/5) and tetracycline 20.0% (1/5), but they were susceptible to chloramphenicol, erythromycin, ertapenem and gentamicin. In the present study, 19.5% (7/36) C. coli strains isolated from pigs were identified as multidrug-resistant (MDR) bacteria. The obtained results demonstrated that pigs especially, but cattle to, can be considered important natural reservoirs for zoonotic multidrug-resistant Campylobacter strains, having a stimulating effect for further studies aiming at the molecular screening of the genotypic antimicrobial resistance processing of a higher number of samples.

弯曲杆菌属被认为是人类胃肠道感染发展中最常见的病原体之一。当前的研究旨在增强对弯曲杆菌属的发生和分子特征的了解。对一年内从九个罗马尼亚屠宰场收集的猪和牛的盲肠样本（n  = 56）进行检测，并确定分离菌株的抗菌谱。所有弯曲杆菌属。 根据 EURL 协议和委员会实施决定第 2020/1729 号，对从猪和牛盲肠样本中分离出的菌株（n = 41）进行了抗菌药物耐药性分析。大肠杆菌的患病率。猪盲肠样本中空肠弯曲菌的患病率为 92.3% (36/39)，牛源样本中空肠弯曲菌的患病率为29.4% (5/17)。从猪中分离出的大肠杆菌菌株被证明对四环素75％（27/36）、环丙沙星69.4％（25/36）、红霉素8.3％（3/36）、厄他培南2.8％（1/36）和庆大霉素2.8％耐药（ 1/36)，但未观察到对氯霉素的耐药性。牛源空肠弯曲菌对环丙沙星60.0%（3/5）和四环素20.0%（1/5）耐药，但对氯霉素、红霉素、厄他培南和庆大霉素敏感。在本研究中，从猪身上分离出的 19.5% (7/36)大肠杆菌菌株被鉴定为多重耐药 (MDR) 细菌。所获得的结果表明，猪，尤其是牛，可以被认为是人畜共患多重耐药弯曲杆菌菌株的重要天然宿主，对进一步研究更多样本的基因型抗菌药物耐药性处理的分子筛选具有刺激作用。
