Abstract

Klebsiella pneumoniae is ubiquitous and known to be a notorious pathogen of humans, animals, and plant-based foods. is a recognized trafficker of antibiotic resistance genes (ARGs) between and from different ecological niches. A total of 775 samples ( = 775) were collected from September 2017 to August 2019 from humans, animals, and environmental sources by applying the random convenient sampling technique. A total of 120 (15.7%) samples were confirmed as . The distribution of among humans, the environment, and animals was 17.1, 12.38, and 10%, respectively. Isolates have shown significant resistance against all the subjected antibiotics agents except colistin. ARGs profiling revealed that the highest percentage prevalence (67.5%) of was estimated in the isolates, and various carbapenem resistance genes that were found in the study were (43.3%), (38%), and (1.67%) . Overall, 21 distinct sequence types (ST) and 13 clonal complexes (CCs) were found through the multi-locus sequence typing (MLST) analysis. Taking together, the distribution of multi-drug resistance (MDR) clones in the  community and associated environment is alarming for the health care system of the country. Health policymakers should consider the role of all the integral parts of humans, animals, and the associated environment intently to cope with this serious public and animal health concern.

摘要

肺炎克雷伯菌广泛存在,是人类、动物和植物性食品中臭名昭著的病原体。它是不同生态位之间抗生素耐药基因(ARGs)的公认传播者。2017年9月至2019年8月期间,采用随机便利抽样技术,从人类、动物和环境来源共采集了775份样本(n = 775)。共有120份(15.7%)样本被确认为肺炎克雷伯菌。肺炎克雷伯菌在人类、环境和动物中的分布分别为17.1%、12.38%和10%。分离株对除黏菌素外的所有受试抗生素均表现出显著耐药性。ARGs分析显示,分离株中肺炎克雷伯菌的最高流行率估计为67.5%,研究中发现的各种碳青霉烯耐药基因分别为blaKPC(43.3%)、blaNDM(38%)和blaOXA-48(1.67%)。总体而言,通过多位点序列分型(MLST)分析发现了21种不同的序列类型(ST)和13个克隆复合体(CCs)。综合来看,多药耐药(MDR)肺炎克雷伯菌克隆在社区和相关环境中的分布对该国的医疗保健系统构成了警报。卫生政策制定者应认真考虑人类、动物和相关环境所有组成部分的作用,以应对这一严重的公共和动物健康问题。
