Background

Sepsis is an acute response to infection; rapid detection of pathogens is essential. In this work, the time to positivity (TTP) of blood culture (BC), a key factor for species diagnosis, was studied.

Methods

In the experimental phase, six bacterial reference strains were tested under varying conditions, and three years of clinical blood culture data were reviewed. A total of 4,924 first positive BC bottles from 3864 patients hospitalized from 2019 to 2021 were analysed.

Results

Experimental results revealed that reducing the inoculum by a factor of 10 increased the TTP by an average of 1.5 hours. A blood sample volume between 1 and 3 mL per vial significantly improved bacterial detection. Each hour of delay before incubation reduced the TTP by 21 minutes; however, the overall TTP was still prolonged. Bacterial growth and viability were preserved at room temperature for up to 24 h. TTP could be exploited as a first diagnostic tool, as it significantly varied between species. Staphylococcus aureus can be differentiated from coagulase-negative staphylococci when the TTP is <12 hours (Specificity (Sp) = 0.95, positive predictive value (PPV) = 62 %, negative predictive value (NPV) = 76 %), and Enterobacteriaceae can be differentiated from Pseudomonas aeruginosa under the same threshold (Sensibility (Se) = 0.70, Sp = 0.93, PPV = 99 %). A TTP >15 hours exclude clinically relevant pathogens such as S. pneumoniae, S. agalactiae, and S. pyogenes.

Conclusion

This work shows how preanalytical factors play a major role in the time required for diagnosis, and highlights the potential of the TTP as a prediagnostic tool to improve sepsis management.
脓毒症是对感染的急性反应;快速检测病原体至关重要。本文对血培养(BC)的阳性时间(time to positive, TTP)这一物种诊断的关键因素进行了研究。方法在实验阶段,采用不同条件下的6种细菌对照菌株进行检测,并回顾3年临床血培养资料。分析了2019年至2021年住院3864例患者的4924个首次阳性BC瓶。结果接种量减少1 / 10可使TTP平均提高1.5 h。每瓶1至3毫升的血液样本量可显著提高细菌检测。孵育前每延迟1小时,TTP减少21分钟;然而,整个tpp仍被延长。细菌的生长和活力在室温下保存了24小时。TTP可以作为第一个诊断工具,因为它在物种之间存在显着差异。当TTP = 12 h时,金黄色葡萄球菌可与凝固酶阴性葡萄球菌区分(特异性(Sp) = 0.95,阳性预测值(PPV) = 62%,阴性预测值(NPV) = 76%),在相同阈值下,肠杆菌科可与铜绿假单胞菌区分(敏感性(Se) = 0.70, Sp = 0.93, PPV = 99%)。TTP 15小时排除临床相关病原体,如肺炎链球菌、无乳链球菌和化脓性链球菌。结论本研究显示了分析前因素在诊断所需时间中发挥的重要作用,并强调了TTP作为一种改善脓毒症管理的预诊断工具的潜力。

Molecular diagnostics have transformed clinical microbiology by enabling rapid, accurate, and highly sensitive detection of infectious agents, significantly improving patient outcomes and public health response. Over the past decade, advances in polymerase chain reaction (PCR), next-generation sequencing (NGS), digital PCR, isothermal amplification, and CRISPR-based assays have enhanced pathogen identification, antimicrobial resistance profiling, and outbreak investigation. These technologies have been instrumental in detecting and monitoring emerging and re-emerging viral pathogens such as SARS-CoV-2, Nipah, Zika, H5N1 avian influenza, Mpox, Ebola, Marburg, and MERS-CoV. Molecular diagnostics also play a critical role in antimicrobial resistance surveillance and hospital infection control by enabling high-resolution tracking of resistance genes and pathogen transmission dynamics. Despite these achievements, challenges remain regarding implementation costs, technical expertise, infrastructure, and the need for global standardization. Future directions focus on developing cost-effective, point-of-care molecular platforms, integrating artificial intelligence and bioinformatics for enhanced interpretation, and applying these technologies within One Health and environmental surveillance frameworks. These innovations will be pivotal for early outbreak detection, real-time data-driven decision-making, and equitable access to advanced diagnostics worldwide. Ultimately, molecular diagnostics are poised to remain the cornerstone of precision medicine and infectious disease control in the era of global health challenges.
分子诊断通过能够快速、准确和高度敏感地检测感染因子,显著改善了患者的治疗效果和公共卫生反应,改变了临床微生物学。在过去的十年中,聚合酶链反应(PCR)、新一代测序(NGS)、数字PCR、等温扩增和基于crispr的检测技术的进步加强了病原体鉴定、抗菌素耐药性分析和疫情调查。这些技术有助于发现和监测新出现和再出现的病毒性病原体,如SARS-CoV-2、尼帕病毒、寨卡病毒、H5N1禽流感、Mpox、埃博拉病毒、马尔堡病毒和中东呼吸综合征冠状病毒。分子诊断通过实现耐药性基因和病原体传播动态的高分辨率跟踪,在抗菌素耐药性监测和医院感染控制中也发挥着关键作用。尽管取得了这些成就,但在实施成本、技术专长、基础设施和全球标准化需求方面仍然存在挑战。未来的方向侧重于开发具有成本效益的护理点分子平台,整合人工智能和生物信息学以增强解释,并在“同一个健康”和环境监测框架内应用这些技术。这些创新对于及早发现疫情、实时数据驱动的决策以及在全世界公平获得先进诊断方法至关重要。最终,在全球健康挑战的时代,分子诊断仍将是精准医学和传染病控制的基石。

Objectives

GPR56, an adhesion G protein-coupled receptor, and CD99, a cell-surface glycoprotein, have emerged as important immunomodulators in HIV infection. GPR56 plays a crucial role in T cell migration, activation, and the interaction between the virus and the host cell. Concurrently, CD99 is implicated in regulating key processes such as T cell adhesion, migration, and apoptotic signaling. This study aimed to investigate their dynamic expression in T-cell subsets as potential biomarkers for AIDS progression and diagnosis.

Methods

Differentially expressed genes in T cells were screened using single-cell RNA sequencing. Experimental validation was performed by flow cytometry on peripheral blood samples from 36 PLWH (male:31, female:5, age: 41.58±12.42) and 35 healthy controls (male:25, female:10, age: 32.17±12.09). Systematically evaluated the protein expression profiles of GPR56 and CD99 on the surface of T cells. The Pearson method assessed correlation, and receiver operating characteristic (ROC) analysis evaluated diagnostic performance.

Results

GPR56 expression on CD8⁺ T cells increased significantly with disease progression (P < 0.05), while CD99 expression remained stable across stages. The CD8⁺GPR56⁺CD99⁺ T-cell subset demonstrated high diagnostic accuracy for HIV infection (AUC = 0.90), with frequencies that increased progressively with disease severity. Moderate co-expression of GPR56 and CD99 was observed in CD8⁺ T cells in both cohorts. In contrast, CD4⁺GPR56⁺ T cells showed no discriminative capacity between early-stage patients and controls.

Conclusions

GPR56 and CD99 exhibit distinct expression patterns during HIV infection. The CD8⁺GPR56⁺ and CD8⁺GPR56⁺CD99⁺ T-cell subsets serve as potent stage-specific biomarkers, with combined GPR56/CD99 analysis enhancing diagnostic precision for advanced AIDS.
gpr56是一种粘附G蛋白偶联受体,CD99是一种细胞表面糖蛋白,它们是HIV感染中重要的免疫调节剂。GPR56在T细胞迁移、激活以及病毒与宿主细胞的相互作用中起着至关重要的作用。同时,CD99还参与调节关键过程,如T细胞粘附、迁移和凋亡信号传导。这项研究旨在研究它们在t细胞亚群中的动态表达,作为艾滋病进展和诊断的潜在生物标志物。方法采用单细胞RNA测序技术筛选T细胞中差异表达基因。采用流式细胞术对36例PLWH(男31例,女5例,年龄41.58±12.42)和35例健康对照(男25例,女10例,年龄32.17±12.09)的外周血进行了实验验证。系统评价GPR56和CD99在T细胞表面的蛋白表达谱。Pearson方法评估相关性,受试者工作特征(ROC)分析评估诊断效果。结果gpr56在CD8 + T细胞上的表达随疾病进展而显著升高(P < 0.05),而CD99在各阶段的表达保持稳定。CD8 + GPR56 + CD99 + t细胞亚群对HIV感染的诊断准确率很高(AUC = 0.90),其频率随着疾病严重程度的增加而逐渐增加。在两个队列的CD8 + T细胞中均观察到GPR56和CD99的中度共表达。相比之下,CD4 + GPR56 + T细胞在早期患者和对照组之间没有表现出区分能力。结论sgpr56和CD99在HIV感染过程中表现出不同的表达模式。CD8 + GPR56 +和CD8 + GPR56 + CD99 + t细胞亚群是有效的阶段特异性生物标志物,GPR56/CD99联合分析提高了晚期艾滋病的诊断精度。

Despite the life-saving benefits of the vaccination with the live attenuated oral polio vaccine, or Sabin (OPV), OPV still evolves rapidly to lose attenuating determinants critical to the reacquisition of virulence, resulting in vaccine-derived, virulent poliovirus variants. The circulation of these variants within under-immunized populations leads to the further evolution of circulating, vaccine-derived poliovirus with increased transmission capacity, representing a significant risk of polio re-emergence. Although the wild poliovirus type 2 (WPV2) had been declared as eradicated worldwide in 2015, outbreaks of circulating VDPV-type 2 (cVDPV2) have been increasingly reported, especially after the tOPV-bOPV switch that occurred in 2016, which resulted in building a cohort of susceptible individuals with lower type 2 intestinal immunity. Since the response to outbreaks is done through conducting supplementary immunization activities (SIAs) using type-2 containing OPV, this carries a risk of mutations, especially with suboptimum coverage and potential further circulation. The recent detection of outbreaks of cVDPV2 in some countries necessitated the development of a genetically stable novel oral polio vaccine type 2 (nOPV-2) to decrease the chances of mutations and hence outbreaks. This review highlights the recent outbreaks of VDPV serotypes, emphasizing the role of the World Health Organization and the Global Polio Eradication Initiative in detecting and controlling VDPV outbreaks. The emerging VDPV, strategies implemented, reported clinical trials, and proposals for developing nOPV. The way the review is presented will encourage assertiveness, assist in posing open-ended questions, and provide several ideas for further research.
尽管口服脊髓灰质炎减毒活疫苗或Sabin (OPV)疫苗接种可带来挽救生命的益处,但口服脊髓灰质炎疫苗仍会迅速进化,失去对重新获得毒力至关重要的减毒决定因素,从而导致疫苗衍生的强毒脊髓灰质炎病毒变体。这些变异在免疫接种不足的人群中传播,导致循环的疫苗衍生脊髓灰质炎病毒进一步演变,传播能力增强,代表脊髓灰质炎再次出现的重大风险。尽管野生脊髓灰质炎病毒2型(WPV2)已于2015年在全球范围内被宣布根除,但循环脊灰病毒2型(cVDPV2)暴发的报道越来越多,特别是在2016年发生tOPV-bOPV转换之后,这导致建立了一个2型肠道免疫力较低的易感个体队列。由于对疫情的应对是通过使用含2型口服脊髓灰质炎疫苗开展补充免疫活动(SIAs)来完成的,这有突变的风险,特别是在覆盖率不理想和可能进一步传播的情况下。最近在一些国家发现了cVDPV2的暴发,因此有必要开发一种遗传稳定的新型口服脊髓灰质炎2型疫苗(nOPV-2),以减少突变和暴发的机会。这篇综述强调了最近暴发的脊髓灰质炎病毒血清型,强调了世界卫生组织和全球根除脊髓灰质炎行动在发现和控制脊髓灰质炎病毒暴发方面的作用。新兴的VDPV,实施的策略,报告的临床试验,以及发展nOPV的建议。评论的呈现方式将鼓励自信,有助于提出开放式问题,并为进一步的研究提供一些想法。

Background

The DiaSorin LIAISON® QuantiFERON-TB Gold Plus test offers automation advantages over the standard QIAGEN ELISA; however, data comparing the two methods in pregnant women are lacking. We assessed the categorical and quantitative agreement between these interferon-gamma release assay platforms for latent tuberculosis infection (LTBI) detection in a cohort of pregnant women in Uganda.

Methods

In this cross-sectional diagnostic comparison, 261 pregnant women were enrolled at Kawempe National Referral Hospital in Kampala, Uganda (September–December 2020). Plasma samples were initially tested with QIAGEN ELISA (QFT-ELISA) in 2021, stored at −80°C, and retested in 2025 with both LIAISON® chemiluminescent immunoassay (QFT-CLIA) and QFT-ELISA. Agreement was assessed using Cohen's kappa, Bland-Altman analysis, and Deming regression analyses. Stability over four years was evaluated using weighted kappa and transition analyses. Subgroup analyses examined agreement by HIV status and trimester

Results

Of the 261 enrolled participants, 231 samples (88.5 %) remained viable after four years storage. Overall agreement between QFT-CLIA and QFT-ELISA in 2025 was 90.5 % (Cohen's Kappa 0.82; 95 % CI: 0.75-0.89). Bland-Altman analysis showed minimal systematic bias (mean difference for TB1-Nil: +0.046 IU/mL, p = 0.608, TB2 Nil: +0.0776 IU/mL, p = 0.3175), and Deming regression confirmed linearity (slope, 0.94-0.96). Among the 187 samples that remained QFT-stable between 2021 and 2025, the agreement improved to 98.4 % (kappa 0.97; 95 % CI: 0.94-1.00), with category-specific agreement of 93.6 %, 97.5 %, and 100 % for positive, negative, and indeterminate results, respectively. Four-year stability varied according to baseline classification: 57.1 % for positive samples, 97.5 % for negative samples, and 75.0 % for indeterminate samples. Agreement was similar between HIV-positive (84.6 %, Kappa 0.76) and HIV-negative participants (90.8 %, Kappa 0.82; p = 0.357).

Conclusions

The LIAISON® platform demonstrated excellent agreement with the QIAGEN ELISA for LTBI detection during pregnancy, particularly when storage effects were minimized. Long-term cryopreservation disproportionately affects positive samples. The automation of the LIAISON® platform supports high-throughput implementation in antenatal care settings; however, fresh sample testing should be prioritized for clinical decision-making.
与标准QIAGEN ELISA相比,DiaSorin LIAISON®QuantiFERON-TB Gold Plus测试具有自动化优势;然而,在孕妇中比较两种方法的数据缺乏。我们评估了这些干扰素γ释放检测平台在乌干达一组孕妇中检测潜伏结核感染(LTBI)的分类和定量一致性。方法在这项横断面诊断比较中,于2020年9月至12月在乌干达坎帕拉的Kawempe国家转诊医院登记了261名孕妇。血浆样品于2021年首次使用QIAGEN ELISA (QFT-ELISA)进行检测,保存于- 80°C,并于2025年使用LIAISON®化学发光免疫测定(QFT-CLIA)和QFT-ELISA进行复检。采用Cohen’s kappa分析、Bland-Altman分析和Deming回归分析评估一致性。使用加权kappa和过渡分析评估四年以上的稳定性。亚组分析检查了HIV状态和妊娠期的一致性。结果在261名登记的参与者中,231份样本(88.5%)在4年的储存后仍然存活。2025年QFT-CLIA和QFT-ELISA的总体一致性为90.5% (Cohen’s Kappa 0.82; 95% CI: 0.75-0.89)。Bland-Altman分析显示最小的系统偏差(TB1-Nil的平均差异为+0.046 IU/mL, p = 0.608, TB2 -Nil的平均差异为+0.0776 IU/mL, p = 0.3175), Deming回归证实线性(斜率为0.94-0.96)。在2021年至2025年间保持qft稳定的187个样本中,一致性提高到98.4% (kappa 0.97; 95% CI: 0.94-1.00),阳性、阴性和不确定结果的类别特异性一致性分别为93.6%、97.5%和100%。四年稳定性根据基线分类而变化:阳性样品57.1%,阴性样品97.5%,不确定样品75.0%。hiv阳性参与者(84.6%,Kappa 0.76)和hiv阴性参与者(90.8%,Kappa 0.82, p = 0.357)之间的一致性相似。结论:LIAISON®平台与QIAGEN ELISA在妊娠期LTBI检测中表现出良好的一致性,特别是在储存影响最小化的情况下。长期低温保存对阳性样品的影响不成比例。LIAISON®平台的自动化支持产前保健设置中的高通量实施;然而,临床决策应优先考虑新鲜样本检测。

Since November 2023, an increase in M. pneumoniae respiratory infections has been observed in France. Macrolides are the reference treatment and are indicated as first-line therapy. Macrolide-resistant strains have been described in clinical isolates, especially in Asian countries. In the present manuscript, we report the persistence of an M. pneumoniae strain from an immunocompromised child with CCR2 deficiency on prophylactic azithromycin treatment. Antimicrobial susceptibility testing showed acquisition of macrolide resistance after treatment with azithromycin. Molecular typing using two typing methods revealed the persistence of the same strain over time. This case highlights the need for access to rapid detection tools to determine the causative pathogen and potential antimicrobial resistance mechanisms. This is particularly important for patients with comorbidities receiving prophylactic antibiotics and require additional caution. Acquisition of resistance can lead to complications and extended hospitalisation. Higher molecular resolution would be useful for the detection of putative heteroresistance in M. pneumoniae.
自2023年11月以来,法国观察到肺炎支原体呼吸道感染有所增加。大环内酯类药物是参考治疗,是一线治疗。临床分离株中有大环内酯耐药菌株,特别是在亚洲国家。在本文中,我们报道了一名免疫功能低下的CCR2缺乏症儿童在预防性阿奇霉素治疗后持续存在肺炎支原体菌株。药物敏感性试验显示阿奇霉素治疗后获得大环内酯类耐药。使用两种分型方法进行分子分型,揭示了同一菌株随时间的持久性。这一病例突出表明,需要获得快速检测工具,以确定致病病原体和潜在的抗微生物药物耐药性机制。这对接受预防性抗生素治疗的合并症患者尤其重要,需要格外谨慎。获得耐药性可导致并发症和延长住院时间。更高的分子分辨率将有助于检测肺炎支原体推定的异源耐药性。

Metallo-β-lactamase (MBL)-producing carbapenemase-producing Enterobacterales (CPE) present significant therapeutic challenges due to resistance to most β-lactam agents, including carbapenems. Aztreonam combined with avibactam (ATM/AVI) provides a promising treatment strategy, but standardized antimicrobial susceptibility testing (AST) methods remain limited. This study evaluated the performance of the MTS™ ATM/AVI gradient strip (Liofilchem) with the CLSI-recommended ceftazidime-avibactam plus aztreonam (CZA/ATM) broth disk elution (BDE) method in 36 CPE and 9 Stenotrophomonas maltophilia clinical isolates. Categorical agreement between these methods was 97.2 % for CPE and 88.9 % for S. maltophilia. Whole-genome sequencing was used for discrepancy analysis. Based on accuracy, reproducibility, and ease of use, the ATM/AVI gradient strip was selected as the preferred method for clinical laboratory testing.
产生金属β-内酰胺酶(MBL)的产碳青霉烯酶肠杆菌(CPE)由于对大多数β-内酰胺类药物(包括碳青霉烯类)的耐药性而面临重大的治疗挑战。氨曲南联合阿维巴坦(ATM/AVI)是一种很有前景的治疗策略,但标准化的抗菌药物敏感性试验(AST)方法仍然有限。本研究采用clsi推荐的头孢他啶-阿维巴坦加氨曲仑(CZA/ATM)肉汤盘洗脱法(BDE)对36株CPE和9株嗜麦芽寡养单胞菌临床分离株进行了MTS™ATM/AVI梯度试纸条(Liofilchem)检测。CPE和嗜麦芽链球菌的分类符合率分别为97.2%和88.9%。采用全基因组测序进行差异分析。基于准确性、重现性和易用性,我们选择ATM/AVI梯度试纸作为临床实验室检测的首选方法。
