We thoroughly characterized the virological and pathogenic features of eight different pandemic SARS-CoV-2 strains, from the WT strain to current circulating sublineage EG.5.1, both in vitro and in vivo. Besides detailed virological features observed in Vero E6 cells, the Omicron variants, from BA.1 to EG.5.1, exhibited enhanced infectious effects to upper respiratory tract in K18 human angiotensin-converting enzyme (ACE2) (K18 hACE2) transgenic mice. Both XBB.1.9.1 and EG.5.1 presented stronger tropism to brain, which could be the main reason for the increased lethal effects on mice. In addition, the pathogenesis comparisons among all these viruses in C57BL/6JGpt mice indicated that Omicron variant BA.1 and two new sublineages XBB.1.9.1 and EG.5.1 possessed dual tropisms to both human and mice, which were further confirmed by subsequent bioinformatic analyses and actual affinity comparison between viral RBDs and mouse or human receptor ACE2. Furthermore, the immunocompromised BKS-db mice were found to be more susceptible to Omicron strains compared to C57BL/6JGpt mice, which revealed that viral infectivity was determined by both its affinity to the host receptor and host immunocompetence. Thus, this study not only contributes to a systematic understanding of the pathogenic features of SARS-CoV-2 in mice, but also provides new insights to combat potential future surges of new SARS-CoV-2 variants.</p></div>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"96 11","pages":""},"PeriodicalIF":6.8,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142667973","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}

In the summer of 2022, an unusual outbreak of enteroviral central nervous system (CNS) infections occurred that was attributed to CVB2. Cerebrospinal fluid (CSF) samples collected from patients in 2015–2022 were tested for enterovirus via RT-PCR, followed by Sanger sequencing for positive cases. CVB2 samples were further sequenced in the P1 region using NGS. A total of 30 CSF samples were identified as CVB2, with 60% of these cases occurring between June and August 2022. The 2022 CVB2 variants were associated with severe clinical symptoms, including encephalitis (50%) and ataxia (27.8%). Samples from 2015 to 2020 were also included due to the absence of these symptoms. Phylogenetic analysis revealed that CVB2 strains from 2019 to 2020 were also distinct from those obtained in 2022. Amino acid analysis of the capsid proteins VP1, VP2, and VP3 identified three unique substitutions with potential antigenic significance in the 2022 variant: S67A in VP2, and T93A and E274D in VP1. These substitutions were not present in earlier strains or reported in the literature, suggesting they may influence the virus's virulence. The clinical observations from this study highlight new patterns of CVB2 infection in the CNS that had not been previously observed. Additionally, it identifies unique genetic changes in the 2022 CVB2 variant that may account for the increased virulence seen in the 2022 outbreak.

Aptima HPV can not only detect HPV mRNA but also HPV DNA though it is much more efficient at detecting HPV RNA than DNA. Currently, there are few studies on the distribution of HPV E6 and E7 mRNA and DNA in the same individual.

We conducted a retrospective analysis of laboratory results and clinical records about positive CSF cultures reported by the SPARSS network from 2017 to 2023. The study covered three distinct periods: January 2017 to December 2019 (before the COVID-19 pandemic), January 2020 to December 2022 (during the COVID-19 pandemic), and January 2023 to December 2023 (after the COVID-19 pandemic), with a total of 5793 CSF isolates collected. Notably, the proportion of male patients (61.3%) was higher than that of females. After COVID-19, we observed a notable shift in the seasonal peak of CSF pathogens, with a delay of approximately 3 months. Remarkable alterations were evident in both pediatric and adult CSF isolate profiles. In children, the predominant pathogens included coagulase-negative <i>Staphylococcus</i> (CoNS), <i>Streptococcus pneumonia,</i> and <i>Escherichia coli</i>. Notably. After COVID-19, there was a significant decrease in the proportion of CoNS (<i>p</i> = 0.0039) and a notable increase in <i>E. coli</i> (<i>p</i> = 0.0067). In adults, the top three pathogens were CoNS, <i>Acinetobacter baumannii,</i> and <i>Klebsiella pneumoniae</i>.
