Poliovirus is a deadly disease that needs to be eradicated in the world. Recently, issues with circulating vaccine-derived polioviruses (cVDPVs) in the Democratic Republic of the Congo (DRC) have been raised in the country. This article aims to determine the increase in Type 1 cVDPV1 and Type 2 cVDPV2 in the DRC. Relevant articles on PubMed, Google Scholar, ResearchGate, and Web of Science were searched from 2010 to 2023. Our findings indicate that the Democratic Republic of Congo has struggled with polio outbreaks, with the virus primarily linked to cVDPVs produced from vaccines rather than wild poliovirus. These cVDPVs have the potential to revert to their paralyzing capabilities by evolving from the weakened virus seen in the oral polio vaccination (OPV). Several regions in DRC have reported cVDPV outbreaks of cVDPVs. Numerous cVDPV2 outbreaks were documented in various provinces during the 2017–2018 period. Addressing the cVDPV outbreak in the DRC requires a concerted global effort, involving collaboration among governments, international health organizations, and donor agencies. There should be global support and collaboration among governments, international health organizations, and donor agencies to address the cVDPV outbreak in the DRC.
脊髓灰质炎病毒是一种致命疾病,需要在全球范围内根除。最近,刚果民主共和国(DRC)出现了疫苗衍生脊灰病毒(cVDPVs)流行的问题。本文旨在确定刚果民主共和国 1 型 cVDPV1 和 2 型 cVDPV2 的增加情况。我们在 PubMed、Google Scholar、ResearchGate 和 Web of Science 上搜索了 2010 年至 2023 年的相关文章。我们的研究结果表明,刚果民主共和国一直与脊髓灰质炎疫情作斗争,病毒主要与疫苗生产的 cVDPV 有关,而不是野生脊髓灰质炎病毒。这些 cVDPV 有可能从口服脊髓灰质炎疫苗(OPV)中的弱化病毒进化而来,从而恢复其麻痹能力。刚果(金)的多个地区都报告了 cVDPV 的爆发。2017-2018年期间,各省记录了多起cVDPV2疫情。应对刚果民主共和国的 cVDPV 疫情需要全球共同努力,包括各国政府、国际卫生组织和捐助机构之间的协作。各国政府、国际卫生组织和捐助机构应在全球范围内提供支持和协作,以应对刚果民主共和国的cVDPV疫情。

The recent global resurgence of Mpox (formerly monkeypox), primarily transmitted via close contact and respiratory droplets, highlights a significant shift in its epidemiology, particularly among men who have sex with men (MSM). This resurgence underscores the need for robust public health responses and improved surveillance. This comprehensive review of current literature focuses on recent outbreaks, virology, and available treatments. Epidemiological data were gathered from various international health reports and analysed to understand transmission dynamics and outbreak patterns. Mpox, characterised by symptoms like fever and rash, has shown variable clinical presentations, particularly among immunocompromised individuals. Recent outbreaks have prompted the development of new diagnostic methods and treatments, including antivirals like Tecovirimat and vaccines such as MVA-BN. Studies have demonstrated the effectiveness of these vaccines in preventing infection, which is crucial for outbreak containment. The global response to the Mpox resurgence requires integrated strategies combining vaccination, antiviral treatments, and public health policies tailored to high-risk populations. Future efforts should focus on vaccine distribution equity and enhancing diagnostic capabilities to effectively manage and mitigate the impact of Mpox.
主要通过密切接触和呼吸道飞沫传播的痘病毒(原猴痘)最近在全球再次流行,这突显了痘病毒流行病学的重大变化,尤其是在男男性行为者(MSM)中。这种流行病的重新抬头凸显了采取强有力的公共卫生应对措施和改进监测的必要性。本文对当前文献进行了全面回顾,重点关注近期的疫情爆发、病毒学和现有治疗方法。我们从各种国际卫生报告中收集了流行病学数据并进行了分析,以了解传播动态和疫情爆发模式。麻腮风以发热和皮疹等症状为特征,临床表现多种多样,尤其是在免疫力低下的人群中。最近的疫情爆发促使人们开发了新的诊断方法和治疗手段,包括 Tecovirimat 等抗病毒药物和 MVA-BN 等疫苗。研究表明,这些疫苗能有效预防感染,这对遏制疫情爆发至关重要。要在全球范围内应对麻风腮复发,就必须采取综合战略,将疫苗接种、抗病毒治疗和针对高危人群的公共卫生政策结合起来。未来的工作重点应放在疫苗的公平分配和提高诊断能力上,以有效管理和减轻麻风腮的影响。

Objectives

We investigated the genomic epidemiology of extended-spectrum β-lactamase-producing Enterobacter cloacae (ESBL-Ec) isolates from patients and hospital environment to better understand their distribution to help devising effective strategies for infection prevention and control.

Methods

We screened ESBL-Ec at Bugando Medical Center (BMC) in Mwanza, Tanzania. Rectal swabs from orthopedic patients on admission and swabs from the neighboring inanimate environment were collected. Following microbial culture, DNA was extracted from pure ESBL-Ec, and whole-genome sequencing was done. Sequence typing (ST), plasmid replicons, drug resistance, and virulence genes were deciphered using the Rapid Microbial Analysis Pipeline (rMAP).

Results

We obtained 209 ESBL isolates, of which 15 (7.2 %) were ESBL-Ec [8 (53.3 %) from patients and 7 (46.7 %) from the environment]. Seven isolates were novel and eight were diverse, each with a unique ST. All isolates harbored two to five β-lactamase genes, with the predominance of blaCTX-M-15 (15/15), blaOXA-1 (14/15), blaTEM (14/15) and blaACT (12/15). The most common non β-lactam drug resistance genes were aac(3)-IIa (14/15), aac(6′)-Ib-cr (14/15), fosA (14/15), and qnrB1 (12/15), aph(3″)-Ib (10/15) and aph(6)-Id (10/15). Eleven different types of plasmid replicons were identified in 14/15 of the isolates, harboring one to five plasmids, with the most common plasmids being IncFII (11/15) and IncFIB (10/15). All isolates harbored the outer membrane protein (ompA), and curli protein (csg) was in 14/15 isolates.

Conclusion

Admitted orthopedic patients and the hospital environment act as a reservoir of ESBL-Ec with diverse STs and endowed with drug resistance and arsenals of virulence genes, calling for their routine screening on admission for mitigation of potential subsequent infections.
目的我们调查了从患者和医院环境中分离出的产扩展谱β-内酰胺酶肠杆菌(ESBL-Ec)的基因组流行病学,以更好地了解它们的分布情况,从而帮助制定有效的感染预防和控制策略。方法我们在坦桑尼亚姆万扎的布甘多医疗中心(BMC)对 ESBL-Ec 进行了筛查。我们收集了骨科病人入院时的直肠拭子和邻近无生命环境中的拭子。微生物培养后,从纯净的 ESBL-Ec 中提取 DNA 并进行全基因组测序。利用快速微生物分析管道(rMAP)对序列分型(ST)、质粒复制子、耐药性和毒力基因进行了破译。结果我们获得了209株ESBL分离株,其中15株(7.2%)为ESBL-Ec[8株(53.3%)来自患者,7株(46.7%)来自环境]。7 个分离株是新分离株,8 个是多样性分离株,每个分离株都有独特的 ST。所有分离株都携带 2 至 5 个 β-内酰胺酶基因,其中以 blaCTX-M-15 (15/15)、blaOXA-1 (14/15)、blaTEM (14/15)和 blaACT (12/15)为主。最常见的非β-内酰胺类耐药基因是 aac(3)-IIa (14/15)、aac(6′)-Ib-cr (14/15)、fosA (14/15) 和 qnrB1 (12/15)、ph(3″)-Ib (10/15) 和 aph(6)-Id (10/15)。在 14/15 株分离物中发现了 11 种不同类型的质粒复制子,携带 1 至 5 个质粒,其中最常见的质粒是 IncFII(11/15 株)和 IncFIB(10/15 株)。结论入院的骨科患者和医院环境是 ESBL-Ec 的贮藏库,其 STs 多种多样,并具有耐药性和毒力基因库,因此需要在入院时对其进行常规筛查,以减少潜在的后续感染。

Background

Carbapenem-resistant Acinetobacter is of increasing global concern because infections are challenging to treat with standard antibiotics. Here, we identified a previously uncharacterised Acinetobacter sp. clinical isolate as Acinetobacter colistiniresistens co-producing IMP-1 and OXA-58. We also examined expression of genes related to antibiotic susceptibility and drug resistance, including blaIMP.

Methods

The isolate was deposited at the National Institute of Technology and Evaluation (NITE) as Acinetobacter sp. NBRC 110496. Susceptibility was defined according to the Clinical and Laboratory Standards Institute (CLSI) breakpoints. Genomic and clonal analyses were performed to identify species and resistance genes.

Results

The isolate was resistant to β-lactams, including broad-spectrum cephalosporins and carbapenems, polymyxins, and trimethoprim/sulfamethoxazole. Genomic analysis identified the isolate as A. colistiniresistens harbouring blaIMP-1, blaOXA-58, blaOXA-670, aac(6′)-Ib, aac(6′)-Ij, ant(3”)-II, aph(3’)-VI, msrE, mphE, and sul1. Colistin resistance was associated with the eptA-like gene, which encodes a lipid A-modifying enzyme. SNP-based phylogenetic analysis revealed that the strain clustered with other strains isolated in Japan. The IMP-1/OXA-58-producing strain described in this study has a novel integron structure surrounding blaIMP-1, aacA and sul1.

Conclusions

Colistin-resistant IMP-1/OXA-58-co-producing A. colistiniresistens was identified in a patient. This isolate could serve as a reservoir for carbapenemase-producing organisms. This study suggests that screening for colistin-resistant isolates is crucial to preserve colistin as a therapeutic agent for multidrug-resistant bacteria. Identification of this MDR isolate in Asia, and the danger of it spreading worldwide, should raise serious concerns.
背景由于标准抗生素难以治疗的感染,耐碳酸培南的不动杆菌越来越受到全球关注。在此,我们发现了一种以前未定性的临床分离株醋肽杆菌,它能同时产生 IMP-1 和 OXA-58。我们还检测了与抗生素敏感性和耐药性相关的基因(包括 blaIMP)的表达情况。方法该分离株作为 Acinetobacter sp. NBRC 110496 存于国家技术与评估研究所(NITE)。根据临床和实验室标准研究所(CLSI)的断点来确定敏感性。结果该分离菌对β-内酰胺类耐药,包括广谱头孢菌素和碳青霉烯类、多粘菌素和三甲双胍/磺胺甲噁唑。基因组分析确定该分离株为大肠杆菌,含有 blaIMP-1、blaOXA-58、blaOXA-670、aac(6′)-Ib、aac(6′)-Ij、ant(3")-II、aph(3')-VI、msrE、mphE 和 sul1。秋水仙素抗性与 eptA-like 基因有关,该基因编码一种脂质 A-修饰酶。基于 SNP 的系统发育分析表明,该菌株与日本分离的其他菌株存在聚类。本研究中描述的产 IMP-1/OXA-58 菌株具有围绕 blaIMP-1、aacA 和 sul1 的新型整合子结构。该分离株可能是产碳青霉烯酶菌的储库。这项研究表明,筛查耐大肠菌素的分离株对于保留大肠菌素作为耐多药细菌的治疗药物至关重要。在亚洲发现这种耐多药分离株以及它在全球传播的危险应引起人们的严重关注。

The IMP-1/OXA-58-producing strain described in this study has a novel integron structure surrounding <em>bla</em><sub>IMP-1</sub>, <em>aacA</em> and <em>sul1</em>.</div></div><div><h3>Conclusions</h3><div>Colistin-resistant IMP-1/OXA-58-co-producing <em>A. colistiniresistens</em> was identified in a patient. This isolate could serve as a reservoir for carbapenemase-producing organisms. This study suggests that screening for colistin-resistant isolates is crucial to preserve colistin as a therapeutic agent for multidrug-resistant bacteria. Identification of this MDR isolate in Asia, and the danger of it spreading worldwide, should raise serious concerns.</div></div>","PeriodicalId":38074,"journal":{"name":"New Microbes and New Infections","volume":"62 ","pages":"Article 101484"},"PeriodicalIF":2.9,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142318766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
