Clinical specimens included blood, bronchoalveolar lavage fluid (BALF), sputum, hydrothorax and cerebrospinal fluid (CSF) . mNGS and conventional culture were performed to compare detection rates and microbial community profiles.\u003Cbr>Results: Among 67 cases, mNGS identified pathogens in 89.55%(60/67), compared to 20.90%(14/67) by traditional culture. Of 14 dual-positive cases, only 1 (1/14, 7.14%) showed complete concordance, while most exhibited discordance or partial genus-level overlap. mNGS further detected viral co-infections in 44.78%(30/67) and identified fastidious/non-culturable pathogens such as enterovirus, human herpesvirus type 1, and Mycobacterium tuberculosis. Patients with chronic diseases were more susceptible to EB virus infections.\u003Cbr>Conclusion: mNGS significantly enhances pathogen detection in pulmonary infections, supports targeted antimicrobial therapy, and holds potential for contributing to clinical outcomes and reducing antibiotic resistance.\u003Cbr>Keywords: mNGS, pulmonary infection, pathogens, antibiotic resistance, detection |\n| --- |\n| Introduction\u003Cbr>Pneumonia is frequently observed in clinical settings and is typically caused by pathogens such as influenza A and B viruses, coronaviruses including SARS-CoV, MERS-CoV, and SARS-CoV-2, Klebsiella pneumoniae, Candida albicans, Pseudomonas aeruginosa, and Mycobacterium tuberculosis.1–3 These pathogens can cause varying degrees of damage to lung tissue. If anti-infective treatments are ineffective, there is a risk of severe decline in lung function or even respiratory failure, which can be life-threatening.4 The reference standard for diagnosing pulmonary infections primarily relies on the isolation and culture of pathogens, complemented by antimicrobial susceptibility testing to guide therapy.5,6 However, this culture-based approach has several critical limitations. First, the turnaround time is lengthy, typically requiring 48–72 hours, which delays diagnosis.7 Second, it has limited sensitivity for detecting fungal pathogens such as Aspergillus spp. and Cryptococcus spp., making the early diagnosis of fungal pneumoni","cbCaidmJGxls5J1U","https://ap.wps.com/l/cbCaidmJGxls5J1U","pdf",451274,"English","# Purpose\n# Methods\n# Results\n# Conclusion\n# Introduction","[{\"question\":\"What is the purpose of this study on mNGS and traditional culture?\",\"answer\":\"To evaluate diagnostic accuracy and clinical applicability of mNGS for pulmonary infections by comparing it with traditional culture methods in a TCM hospital setting.\"},{\"question\":\"How was the study conducted and who were the participants?\",\"answer\":\"A retrospective cohort enrolled 67 consecutively admitted patients with radiologically and clinically confirmed pulmonary infections between December 2022 and September 2024.\"},{\"question\":\"What were the main findings comparing mNGS with culture?\",\"answer\":\"mNGS detected pathogens in 89.55% of cases versus 20.90% by traditional culture, identified viral co-infections in 44.78%, and detected fastidious/non-culturable pathogens.\"}]","Comparative Evaluation of mNGS and Traditional Culture Methods in Pathogen Detection for Pulmonary Infections | PDF",1790620922]
