Antibiotic resistance genes and bacteria (ARGs and ARB) in vegetable or fruit pose risks to ecological environment health. However, the assessment of ARGs and ARB from one popular vegetable, fresh tomato, has not been carried out before. In this study, high-throughput quantitative PCR and 16S rRNA gene Illumina sequencing technology were used to explore the antibiotic resistance characteristics of bacteria on five common cultivars of fresh tomatoes from supermarket. A total of 191 ARGs and 10 mobile genetic elements (MGEs) were detected on the tomato surfaces. The distribution profile of ARGs and MGEs was different among samples, with the organic tomatoes showing more ARGs and MGEs number and relative abundance. Aminoglycoside resistance genes strA and strB, sulfonamide resistance gene sul1, and multidrug resistance gene qacΔ1-01 were the predominant ARGs. Dominant MGEs were transposase genes, which might promote horizontal gene transfer (HGT) of ARGs. Network analysis indicated that fifteen bacterial families might be the potential hosts of ARGs, and the detected MGEs might have positive correlation with ARGs. These results revealed the bacterial ARGs and MGEs from fresh tomato, which might help guide human to pay more attention to ecological environment impacts of ARGs and ARB on the surfaces of vegetable or fruit |
