摘要

随着抗生素的广泛应用甚至误用,抗生素耐药基因(ARGs)广泛存在于从自然环境到发酵食品等各种环境中,对公众和环境健康构成了新的威胁。实时荧光定量PCR (real-time fluorescence quantitative PCR, qPCR)技术是土壤、水等环境样品中ARGs检测的常用方法。本研究收集了来自中国4个地区的8种泡菜,采用qPCR方法鉴定了13个抗性基因的存在性。结果表明,泡菜共检测到11个耐药基因,所有样品均检测到blaTEM基因,未检测到neo和cat基因。抗性基因的丰度变化,aada1(1.09×105 - 5.94×106册/ g),检测(1.48×105 - 2.2×106册/ g), ermc(1.01×105 - 5.35×105册/ g), hyg(1.35×105 - 1.93×106册/ g), aadd(4.46×105 - 1.60×106册/ g), nat1(1.04×105 - 5.04×105册/ g), nptII(2.17×104 - 1.69×105册/ g), sul1(2.01×105 - 4.60×105册/ g), tetl(1.23×105 - 6.18×105册/ g), shble(1.68×104册/ g),和箍(4.8×104 - 1.9×105册/ g)。我们还讨论了qPCR用于泡菜ARGs分析的特异性和敏感性评估,验证了该方法的可行性和有效性。对泡菜中的细菌进行了分离纯化,并对其耐药性进行了研究。本研究对酸菜抗性基因的风险评估具有重要意义。提出了有效的预防措施,以减少耐药基因的传播,保护公众的饮食健康。

Occurrence and Abundance of Antibiotic Resistance Genes in Chinese Traditional Pickles.

With the widespread application and even misuse of antibiotics, antibiotic resistance genes (ARGs) are extensively present in various environments, from natural environment to fermented foods, posing emerging threat to public and environmental health. The real-time fluorescence quantitative PCR (qPCR) technique is commonly used to detect ARGs of environmental samples such as soil or water. In this study, eight types of pickles were collected from four regions of China and the existence of 13 resistance genes was assessed by qPCR. The results showed that a total of 11 resistance genes were detected in pickles, the blaTEM gene was detected in all samples, and the neo and cat genes were absent. The abundance of resistance genes varied, aada1 (1.09 × 105 to 5.94 × 106 copies/g), blaTEM (1.48 × 105 to 2.2 × 106 copies/g), ermc (1.01 × 105 to 5.35 × 105 copies/g), hyg (1.35 × 105 to 1.93 × 106 copies/g), aadd (4.46 × 105 to 1.60 × 106 copies/g), nat1 (1.04 × 105 to 5.04 × 105 copies/g), nptII (2.17 × 104 to 1.69 × 105 copies/g), sul1 (2.01 × 105 to 4.60 × 105 copies/g), tetl (1.23 × 105 to 6.18 × 105 copies/g), shble (1.68 × 104 copies/g), and stra (4.8 × 104 to 1.9 × 105copies/g). We also discussed the specificity and sensitivity assessment of qPCR applied to ARGs analysis in pickles, verifying the feasibility and validity of the method. Bacteria were isolated and purified from pickles as well and their antimicrobial resistance was studied. This study is of great significance for the risk assessment of resistance genes in pickles. Effective and preventive solutions were proposed to reduce the spread of resistance genes and protect public dietary health.

期刊介绍: Foodborne Pathogens and Disease is one of the most inclusive scientific publications on the many disciplines that contribute to food safety. Spanning an array of issues from "farm-to-fork," the Journal bridges the gap between science and policy to reduce the burden of foodborne illness worldwide. Foodborne Pathogens and Disease coverage includes: Agroterrorism Safety of organically grown and genetically modified foods Emerging pathogens Emergence of drug resistance Methods and technology for rapid and accurate detection Strategies to destroy or control foodborne pathogens Novel strategies for the prevention and control of plant and animal diseases that impact food safety Biosecurity issues and the implications of new regulatory guidelines Impact of changing lifestyles and consumer demands on food safety.
