Abstract：
The emergence of antibiotic resistance in Acinetobacter spp. is a rising public health concern worldwide. The objective of this study was to investigate the prevalence of antibiotic-resistance genes and the virulence of Acinetobacter spp. isolated from soil and crops obtained from agricultural fields in South Korea. Eight Acinetobacter spp. isolates carried various antibiotic resistance genes, such as emrAB (100%), cat/craA (100%), and aadA gene (87.5%). Minimum inhibitory concentration (MIC) analysis revealed that strains harboring antibiotic resistance genes exhibited high resistance to the respective antibiotics, such as colistin, chloramphenicol, and streptomycin. Interestingly, most of these isolates had high capability of biofilm formation and swarming motility, along with faster growth rates. Taken together, our study demonstrated that antibiotic-resistant Acinetobacter isolated from agricultural settings in South Korea not only frequently carries antibiotic resistance genes but also has virulence-related traits.

摘要：
不动杆菌属中抗生素耐药性的出现。是全球范围内日益增加的公共卫生问题。本研究的目的是调查抗生素耐药基因的流行和不动杆菌属的毒力。从韩国农田获得的土壤和作物中分离出来。八个不动杆菌属。分离株携带各种抗生素抗性基因，如emrAB(100%)，猫/craA（100％），和aadA基因(87.5%)。最小抑制浓度（MIC）分析显示，具有抗生素抗性基因的菌株对各自的抗生素表现出高抗性，比如粘菌素,氯霉素,和链霉素.有趣的是,这些分离株中的大多数具有很高的生物膜形成能力和成群运动能力，以及更快的增长率。一起来看,我们的研究表明,从韩国农业环境中分离出的抗生素耐药不动杆菌不仅经常携带抗生素耐药基因,而且具有与毒力相关的性状.
