The ongoing COVID-19 pandemic increases the consumption of antimicrobial substances (ABS) due to the unavailability of approved vaccine(s). To assess the effect of imprudent consumption of ABS during the COVID-19 pandemic, we compare the 2020 prevalence of antidrug resistance (ADR) of Escherichia coli (E. coli) with a similar survey carried out in 2018 in Ahmedabad, India using SARS-CoV-2 gene detection as a marker of ABS usage. We found a significant ADR increase in 2020 compared to 2018 in ambient water bodies, harbouring a higher incidence of ADR E.coli towards non-fluoroquinolone drugs. Effective SARS-CoV-2 genome copies were found to be associated with the ADR prevalence. The prevalence of ADR depends on the efficiency of WWTPs (Wastewater Treatment Plants) and the catchment area in its vicinity. In the year 2018 study, prevalence of ADR was discretely distributed, and the maximum ADR prevalence recorded was ~60%; against the current homogenous ADR increase, and up to 85% of maximum ADR among the incubated E.coli isolated from the river (Sabarmati) and lake (Chandola and Kankaria) samples. Furthermore, wastewater treatment plants showed less increase in comparison to the ambient waters, which eventually imply that although SARS-CoV-2 genes and faecal pollution may be diluted in the ambient waters, as indicated by low C-value and E.coli count, the danger of related aftermath like ADR increase cannot be nullified. Also, Non-fluoroquinolone drugs exhibited overall more resistance than quinolone drugs. Overall, this is probably the first-ever study that traces the COVID-19 pandemic imprints on the prevalence of antidrug resistance (ADR) through wastewater surveillance and hints at monitoring escalation of other environmental health parameters. This study will make the public and policyholders concerned about the optimum use of antibiotics during any kind of treatment.
由于无法获得批准的疫苗,持续的 COVID-19 大流行增加了对抗微生物物质 (ABS) 的消耗。为了评估在 COVID-19 大流行期间不谨慎使用 ABS 的影响,我们将 2020 年大肠杆菌 (E. coli) 的抗药性 (ADR) 流行率与 2018 年在印度艾哈迈达巴德进行的类似调查进行了比较,该调查使用 SARS-CoV-2 基因检测作为 ABS 使用的标志物。我们发现,与 2018 年相比,2020 年在环境水体中,非氟喹诺酮类药物的 E. coli 抗药性发生率更高,ADR 显著增加。发现有效 SARS-CoV-2 基因组拷贝与 ADR 流行率相关。ADR 的流行率取决于污水处理厂 (Wastewater Treatment Plants) 的效率及其附近的集水区。在 2018 年的研究中,ADR 的流行率呈离散分布,记录到的最大 ADR 流行率约为 60%;而当前的 ADR 则呈均匀增加趋势,从从河流(萨巴尔马蒂河)和湖泊(钱德拉湖和坎卡里亚湖)样本中分离出来的孵育大肠杆菌中,最大 ADR 达到 85%。此外,与环境水相比,污水处理厂的增长幅度较小,这最终意味着,尽管 SARS-CoV-2 基因和粪便污染可能在环境水中被稀释,如低 C 值和大肠杆菌计数所表明的那样,但不能消除与相关后果(如 ADR 增加)相关的危险。此外,非氟喹诺酮类药物总体上比喹诺酮类药物表现出更高的耐药性。总体而言,这可能是首次通过废水监测追踪 COVID-19 大流行对抗药性(ADR)流行率的影响的研究,并暗示需要监测其他环境卫生参数的升级。这项研究将使公众和政策制定者关注在任何治疗中抗生素的最佳使用。
