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.
