INTRODUCTION
is an ubiquitous foodborne pathogen that represents a serious threat to public health and the food industry.
METHODS
In this study Whole Genome Sequencing (WGS) was used to characterize 160 isolates obtained from 22,593 different food sources in Montenegro during the years 2014-2022.
RESULTS
Isolates belonged to 21 different clonal complexes (CCs), 22 sequence types (STs) and 73 core genome multilocus sequence types (cgMLST) revealing a high diversity. The most prevalent STs were ST8 ( = 29), ST9 ( = 31), ST121 ( = 19) and ST155 ( = 20). All isolates carried virulence genes (VGs), 111 isolates carried mobile genetic elements (MGEs) (ranging from 1 to 7 MGEs) and 101 isolates carried plasmids (ranging from 1 to 3 plasmids). All isolates carried the intrinsic resistance genes and . None of the isolates carried acquired antimicrobial resistance genes (ARGs).
DISCUSSION/CONCLUSION: Continuous monitoring and surveillance of is needed for improving and ameliorating the public health.
引言
是一种普遍存在的食源性病原体，对公众健康和食品工业构成严重威胁。
方法
在本研究中，全基因组测序（WGS）被用于对2014年至2022年期间从黑山22593种不同食物来源中获得的160株分离株进行特征分析。
结果
分离株属于21种不同的克隆复合体（CCs）、22种序列类型（STs）和73种核心基因组多位点序列类型（cgMLST），显示出高度的多样性。最常见的STs是ST8（=29）、ST9（=31）、ST121（=19）和ST155（=20）。所有分离株都携带毒力基因（VGs），111株携带移动遗传元件（MGEs）（范围为1至7个MGEs），101株携带质粒（范围为1至3个质粒）。所有分离株都携带固有抗性基因和。没有分离株携带获得性抗菌抗性基因（ARGs）。
讨论/结论：需要对进行持续监测，以改善和提升公众健康。
