This study developed a highly sensitive and efficient method for the detection of brucellosis by introducing a one-tube nested quantitative real-time PCR (qPCR) approach, representing a remarkable advance in the field. The method demonstrated an impressive analytical sensitivity of 100 fg/μL, surpassing conventional qPCR and enabling the detection of even low levels of DNA. In addition, the study's comprehensive evaluation of 250 clinical samples revealed a specificity of 100% and a sensitivity of 98.6%, underscoring its reliability and accuracy. Most importantly, the new method significantly improved the detection rate of low-burden samples, reducing cycle threshold values by an average of 6.4. These results underscore the immense potential of this approach to facilitate rapid and accurate brucellosis diagnosis, which is critical for effective disease management and control.
本研究通过引入一种单管巢式定量实时 PCR（qPCR）方法，开发了一种高灵敏度和高效率的布鲁氏菌检测方法，这是该领域的一项重大进展。该方法的分析灵敏度令人印象深刻，达到 100 fg/μL，超过了常规 qPCR，能够检测到甚至低水平的 DNA。此外，该研究对 250 份临床样本的全面评估显示，其特异性为 100%，灵敏度为 98.6%，突出了其可靠性和准确性。最重要的是，该新方法显著提高了低负担样本的检测率，平均降低了 6.4 个循环阈值。这些结果突显了该方法在促进快速、准确的布鲁氏菌病诊断方面的巨大潜力，这对于有效管理和控制疾病至关重要。
