It was first isolated in Europe and has a holarctic distribution, spanning Central Europe, Asia, and Africa. Central Europe has reported the highest reported human seropositivity rate, reaching 30%. Phylogenetic analysis has revealed a close relationship between TAHV and Lumbo virus (LUMV), with 94% amino acid sequence identity in their N proteins. TAHV is mainly transmitted by <i>Aedes</i> mosquitoes, and its vertebrate hosts include hares, rabbits, hedgehogs, and rodents. Flooding during the summer months due to climate change may be a catalyst for the spread of the virus. Despite the enormous potential threat of TAHV and its potential to cause meningitis, there is a notable dearth of information regarding its actual prevalence, the number of symptomatic cases, and its clinical manifestations in humans and animals. To date, no deaths have been attributed to TAHV, which might contribute to an underestimation of its public health significance. Given the anticipated future changes in climatic conditions, TAHV could pose a health threat in Europe and elsewhere. In this review, we summarize recent advancements in TAHV research, highlighting the need for enhanced research and resource allocation for its prevention and control.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we classified this virus and investigated its intrahost genomic diversity using next-generation sequencing. We sequenced HhAV-1 genomes from specimens from seven hedgehogs (two males and five females) with signs of encephalitis that were collected in Buckinghamshire, Gloucestershire, and Cambridgeshire, England, and had died or been euthanised between 2013 and 2024. Analysis of the intrahost populations of these seven HhAV-1 isolates and a previously described isolate revealed the presence of single-nucleotide polymorphisms (SNPs), which were most frequent in open reading frames 5, 6, and 7, encoding glycoprotein 5, the membrane protein, and the nucleocapsid protein. Pairwise comparisons of the eight HhAV-1 variants showed that the nucleotide sequence identity values in their combined complete coding sequences ranged from 76.2% to 100%. The eight HhAV-1 variants also shared at least 82.8% amino acid sequence identity in five domains that are involved in replication and are used for the classification of nidoviruses: 3CLpro, NiRAN, RdRp, ZBD, and HEL1. In a replicase-based phylogenetic tree of members of the family <i>Arteriviridae</i>, the HhAV-1 variants formed a sister cluster to African pouched rat arterivirus.

This review of the aetiology of dengue fever examines the complex interactions between the virus and the immune system and the interaction between viral and host factors and also covers outbreaks, the severity of disease caused by different serotypes, and methods for diagnosis of dengue, such as serological tests, nucleic acid amplification tests, and ELISA assays for detecting the NS1 antigen. Current treatment options and prevention strategies, including vector control measures, environmental interventions, and insect repellents are also discussed.

Nevertheless, there remains a significant gap in our knowledge regarding <i>Glutamicibacter</i> phages, particularly in comparison to those of the related actinobacteria. To date, only two virulent phages infecting <i>G. arilaitensis</i> have been described. To our knowledge, this is the first report on the isolation, characterization, and genome analysis of a temperate phage targeting <i>G. halophytocola</i>, an endophytic bacterium known for its plant-growth-promoting effect. The phage Ph-p5, with siphovirus structure, was isolated from soil. It exhibited a long latent period (120 min), a moderate burst size (87 ± 3 PFU/infected cell), and stability over a wide range of pH and temperature. The circularly permuted linear double-stranded DNA genome of phage Ph-p5, comprising 43,694 bp with a G + C content of 57.1%, contains 65 putative protein-coding sequences and one sequence encoding tRNA. Of the identified open reading frames, 33 were of unknown function, while the remaining ones were grouped into functional modules, including structural proteins, DNA replication and regulation, lysogeny, and lysis. The presence of intact lysogeny-related genes, together with the capacity for lysogenisation of the host strain <i>G. halophytocola</i> BIM B-1594, provides evidence that Ph-p5 is a temperate phage. Phylogenetic analysis demonstrated that phage Ph-p5 belongs to the class <i>Caudoviricetes</i> but exhibits significant divergence from known phages and may be assigned to a new genus, for which we propose the name “<i>Petuglutavirus”</i>.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143184785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
