To assess viral etiologies of hospitalized patients with pulmonary infection, bronchoalveolar lavage fluid (BALF) specimens were collected from non-COVID-19 adult patients (n ​= ​333, including patients with lower respiratory tract infection, tuberculosis, lung cancer, and pulmonary nodules) between November 2020 and November 2021. Multiple common respiratory pathogens were detected using multiplex reverse-transcription polymerase chain reaction. The result showed that at least one virus was identified in 35.44% (118/333) of the cases. Among these, influenza virus was the most commonly identified, followed by the parainfluenza virus, coronavirus, human rhinoviruses, and human respiratory syncytial viruses. The tuberculosis group demonstrated the highest viral detection rate, yet paradoxically exhibited the lowest co-infection rate. In contrast, the highest co-infection frequency was observed in the pulmonary nodules group. Patients with viral infections exhibited more severe clinical symptoms compared to those without detected viral infections. However, this observation was only noted in the lower respiratory tract infection group among the different disease groups. Notably, among patients infected with a specific virus, there were no significant differences in viral load between single and co-infections. Our study identified the major causative agents in hospitalized adult patients with pulmonary infection, offering insights for precise disease diagnosis and the prevention of unnecessary use of antimicrobial drugs.</div></div>","PeriodicalId":23654,"journal":{"name":"Virologica Sinica","volume":"40 2","pages":"Pages 166-175"},"PeriodicalIF":5.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the construction of a wild-type HBoV1 infectious clone has been reported, generating HBoV1 infectious clone carrying foreign reporter genes with suitable insertion sites in its genome while retaining replicative ability remains challenging. Here, HBoV1 infectious clones harboring the 11-amino-acid HiBiT tag at five distinct insertion sites were constructed and evaluated. Only the recombinant HBoV1 carrying the HiBiT tag in the N-terminus of the NS1 protein (HBoV1-HiBiT<sub>NS1</sub>) displayed comparable characteristics to wild-type HBoV1 as determined via the analysis of viral DNA copy number, NanoLuc activity, viral protein expression, and the formation of replication intermediates. Notably, the replication kinetics of HBoV1-HiBiT<sub>NS1</sub> could be examined by monitoring NanoLuc activity, which was noted to be correlated with the viral DNA level. Additionally, we successfully applied HiBiT-tagged HBoV1 for the evaluation of antiviral drug activity and identified ivermectin (EC50 ​= ​2.27 ​μM) as a potent anti-HBoV1 replication drug.
