The global misuse of antimicrobial medication has further exacerbated the problem of antimicrobial resistance (AMR), enriching the pool of genetic mechanisms previously adopted by bacteria to evade antimicrobial drugs. AMR can be either intrinsic or acquired. It can be acquired either by selective genetic modification or by horizontal gene transfer that allows microorganisms to incorporate novel genes from other organisms or environments into their genomes. To avoid an eventual antimicrobial mistreatment, the use of antimicrobials in farm animal has been recently reconsidered in many countries. We present a systematic review of the literature discussing the cases of AMR and the related restrictions applied in North American countries (including Canada, Mexico, and the USA). The Google Scholar, PubMed, Embase, Web of Science, and Cochrane databases were searched to find plausible information on antimicrobial use and resistance in food-producing animals, covering the time period from 2015 to 2024. A total of 580 articles addressing the issue of antibiotic resistance in food-producing animals in North America met our inclusion criteria. Different AMR rates, depending on the bacterium being observed, the antibiotic class being used, and the farm animal being considered, have been identified. We determined that the highest average AMR rates have been observed for pigs (60.63% on average), the medium for cattle (48.94% on average), and the lowest for poultry (28.43% on average). We also found that Cephalosporines, Penicillins, and Tetracyclines are the antibiotic classes with the highest average AMR rates (65.86%, 61.32%, and 58.82%, respectively), whereas the use of Sulfonamides and Quinolones leads to the lowest average AMR (21.59% and 28.07%, respectively). Moreover, our analysis of antibiotic-resistant bacteria shows that and provide the highest average AMR rates (71.81% and 69.48%, respectively), whereas . provides the lowest one (29.75%). The highest average AMR percentage, 57.46%, was observed in Mexico, followed by Canada at 45.22%, and the USA at 42.25%, which is most probably due to the presence of various AMR control strategies, such as stewardship programs and AMR surveillance bodies, existing in Canada and the USA. Our review highlights the need for better strategies and regulations to control the spread of AMR in North America.
全球对抗菌药物的滥用进一步加剧了抗菌药物耐药性(AMR)问题,丰富了细菌此前用于逃避抗菌药物的基因机制库。AMR可以是内在的,也可以是后天获得的。它可以通过选择性基因改造或水平基因转移获得,水平基因转移使微生物能够将来自其他生物体或环境的新基因整合到其基因组中。为避免最终出现抗菌药物滥用的情况,许多国家最近重新审视了农场动物中抗菌药物的使用。我们对讨论北美国家(包括加拿大、墨西哥和美国)AMR情况及相关限制措施的文献进行了系统综述。检索了谷歌学术、PubMed、Embase、科学网和考克兰数据库,以查找有关食用动物抗菌药物使用和耐药性的合理信息,涵盖2015年至2024年的时间段。共有580篇涉及北美食用动物抗生素耐药性问题的文章符合我们的纳入标准。已确定不同的AMR发生率,这取决于所观察的细菌、所使用的抗生素类别以及所考虑的农场动物。我们确定,猪的平均AMR发生率最高(平均为60.63%),牛次之(平均为48.94%),家禽最低(平均为28.43%)。我们还发现,头孢菌素类、青霉素类和四环素类是平均AMR发生率最高的抗生素类别(分别为65.86%、61.32%和58.82%),而磺胺类和喹诺酮类的使用导致的平均AMR最低(分别为21.59%和28.07%)。此外,我们对抗生素耐药菌的分析表明,[此处原文缺失具体细菌名称]和[此处原文缺失具体细菌名称]的平均AMR发生率最高(分别为71.81%和69.48%),而[此处原文缺失具体细菌名称]的发生率最低(29.75%)。墨西哥的平均AMR百分比最高,为57.46%,其次是加拿大,为45.22%,美国为42.25%,这很可能是由于加拿大和美国存在各种AMR控制策略,如管理计划和AMR监测机构。我们的综述强调了在北美需要更好的策略和法规来控制AMR的传播。
