Recent studies have shown that both compounds have equivalent inactivation effects when tested on purified viruses. However, in practical applications, the presence of organic matter is common and can significantly affect disinfectant performance. We conducted several experiments comparing these two disinfectants under different conditions to better understand their practical efficacy. When an infected cell culture medium (serum-free) was used as the test virus, chlorous acid water and sodium hypochlorite solution showed reduced efficacy. This decrease was attributed to the presence of aa in the medium. Notably, sodium hypochlorite solution showed a more pronounced reduction in potency compared with chlorous acid water. In addition, we evaluated the SARS-CoV-2 inactivation effects of chlorous acid water and sodium hypochlorite solution under various organic loading conditions simulating real-world contamination scenarios such as blood, vomit and saliva. The organic materials used included BSA, SRBCs, polypeptone, FBS and artificial saliva. The results showed that chlorous acid water demonstrated superior resilience to organic matter interference compared with sodium hypochlorite solution. These results suggest that chlorous acid water may be more effective than sodium hypochlorite solution in inactivating viruses on contaminated surfaces, particularly in healthcare settings where organic contamination is common. In summary, our research suggests that chlorous acid water may be a more effective disinfectant in practical settings.</p>","PeriodicalId":94366,"journal":{"name":"Access microbiology","volume":"7 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12451309/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133110","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}

We used direct RNA sequencing to comprehensively profile the transcriptomic and epitranscriptomic landscapes of human HEK-AT cells infected with SARS-CoV-2 at 8 h post-infection, compared to mock controls. We analysed viral and host transcriptomes, focusing on gene and transcript expression, isoform usage and RNA m6A modifications. Viral RNA sequencing reads showed 3' end-biassed coverage indicative of subgenomic RNA synthesis, with high expression of <i>N</i> gene subgenomic RNA reads. Sixteen m6A modification sites were consistently identified in the viral genome, primarily within the <i>ORF1ab</i> and <i>S</i> genes. In the human transcriptome, we found 254 positions with significantly altered m6A modification rates, with 119 showing decreased modification and 135 showing increased modification in infected cells. Genes with decreased m6A modifications were enriched in the neurotrophin signalling pathway. Transcript-level analysis identified 19 upregulated and 12 downregulated transcripts. Notably, transcript discovery and quantification revealed a novel isoform of the <i>HIST1H2BK</i> gene, which was significantly more expressed in infected cells compared to mock controls. Isoform switching analysis revealed 24 significant switches involving 21 genes, implicating mitochondrial reprogramming and immune-related pathways.

Diagnostic testing for COVID-19 is critical for understanding epidemiology, contact tracing, case management and controlling the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Real-time reverse transcription PCR test, the gold standard test, involves fairly complex steps and takes nearly 24-48 h to generate the results. GeneXpert is a rapid nucleic-acid-detection-based test approved by the Indian Council of Medical Research, which can shorten the turnaround time significantly. <b>Aim.</b> The study aimed to compare the performance of GeneXpert against the gold standard real-time reverse transcription PCR for SARS-CoV-2. <b>Materials and methods.</b> This retrospective study was conducted at a tertiary care centre from 25 March 2020 to 8 December 2020. The nasopharyngeal/oropharyngeal swabs that were sent to the Viral Research and Diagnostic Laboratory for testing of SARS-CoV-2 by GeneXpert [cartridge-based nucleic acid amplification test (CBNAAT)] were included for the study. A total of 270 samples (220 samples positive and 50 samples negative for SARS-CoV-2 by GeneXpert) were simultaneously tested for real-time reverse transcription PCR. Real-time reverse transcription PCR was considered as gold standard test (reference) for calculating the sensitivity and specificity of the GeneXpert (CBNAAT) test. <b>Results.</b> Out of the total samples tested (<i>n</i>=270) for SARS-CoV-2, 220 were positive, and 50 were negative for SARS-CoV-2 by GeneXpert. Among 220 GeneXpert SARS-CoV-2-positive samples, 118 (53.64%) were also positive by real-time reverse transcription PCR, while 102 (46.36%) showed negative results by real-time reverse transcription PCR. However, 50 GeneXpert negative samples showed 100% agreement with real-time reverse transcription PCR, i.e. they were also negative by real-time reverse transcription PCR. The GeneXpert sensitivity and specificity for COVID-19 were seen to be 100% (95% CI: 96.92-100%) and 32.89% (95% CI: 25.50-40.97%), respectively, as compared to the gold standard real-time reverse transcription PCR test. The positive predictive value and negative predictive value of GeneXpert for COVID-19 were found to be 53.64% and 100%, respectively. <b>Conclusion.</b> This study highlights that the GeneXpert test is highly sensitive and found to be useful in emergency and challenging situations for rapidly ruling out negative cases. However, due to its relatively low specificity, positive results should be confirmed with real-time reverse transcription PCR.
