本研究旨在调查11种市售食用昆虫（小蟋蟀粉、小蟋蟀、蝗虫、粉虫幼虫、巨型蟋蟀）中11个可转移抗生素抗性（AR）基因[erm（A）、erm（B）、erm（C）、vanA、vanB、tet（M）、tet（O）、tet（S）、tet（K）、mecA、blaZ]的发生情况。水蝽、黑蚂蚁、有翅白蚁、犀牛甲虫、蝼蛄、蚕蛹和黑蝎子），以便为风险评估提供第一个基线。在所研究的 AR 基因中，tet(K) 出现频率最高，其次是 erm(B)、tet(S) 和 blaZ。就不同 AR 决定因素的出现而言，样本之间存在很高的变异性。聚类分析和主坐标分析将 11 个样品分为两个主要聚类，一个包括除泰国生产的样品外的所有样品，另一个包括荷兰生产的样品。 (C) 2016 Elsevier B.V. 保留所有权利。
This study was aimed at investigating the occurrence of 11 transferable antibiotic resistance (AR) genes [erm(A), erm(B), erm(C), vanA, vanB, tet(M), tet(O), tet(S), tet(K), mecA, blaZ] in 11 species of marketed edible insects (small crickets powder, small crickets, locusts, mealworm larvae, giant waterbugs, black ants, winged termite alates, rhino beetles, mole crickets, silkworm pupae, and black scorpions) in order to provide a first baseline for risk assessment. Among the AR genes under study, tet(K) occurred with the highest frequency, followed by erm(B), tet(S) and blaZ. A high variability was seen among the samples, in terms of occurrence of different AR determinants. Cluster Analysis and Principal Coordinates Analysis allowed the 11 samples to be grouped in two main clusters, one including all but one samples produced in Thailand and the other including those produced in the Netherlands.
