Given the current lack of effective broad-spectrum antiviral therapies, it is important to investigate the pathogenic mechanisms of viruses using animal models in order to accelerate the development of intervention strategies. This review systematically examines the progress in the development of animal models for enterovirus research, with particular emphasis on non-human primates, rodents, and non-viral infection models. Non-human primates are considered ideal for studying natural enterovirus infections due to their high degree of physiological and immunological similarity to humans. Rodent models, while cost-effective and relatively easy to handle, often rely on the use of viruses with adaptive mutations or immunodeficient animals, which may not fully replicate the human immune response. Non-viral infection models can be used to obtain novel insights into virus-host interactions. Current challenges include the need to overcome discrepancies between animal models and human disease phenotypes, as well as the limitations imposed by the host specificity of viral strains. Future research should integrate multi-omics technologies, organoids, and artificial intelligence to optimize model construction, advance translational research, and provide precise tools for enterovirus prevention and control.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 8","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144590362","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}

Here, we investigated the effects of various classes of antibiotics on <i>Escherichia coli</i> infection by phages that use different receptors, including vitamin B<sub>12</sub> outer membrane transporter (BtuB), lipopolysaccharide (LPS), outer membrane protein A (OmpA), and nucleoside-specific porin (Tsx). Among the antibiotics tested, ampicillin did not affect phage infection, whereas colistin, chloramphenicol, and tetracycline inhibited phage infection irrespective of the phage receptor. In contrast, kanamycin inhibited infection of kanamycin-resistant <i>E. coli</i> by the BtuB-targeting phages, but not by the phages using LPS, OmpA, or Tsx. The receptor-specific antagonistic effect of kanamycin on BtuB-targeting phage infection was stronger than the effect observed with colistin, chloramphenicol, or tetracycline. When using a <i>btuB</i>-knockout mutant, we observed reduced kanamycin accumulation and increased kanamycin resistance compared to wild-type <i>E. coli</i>, suggesting that BtuB might be involved in kanamycin uptake. These results suggest that the antagonism between kanamycin and BtuB-targeting phage infection may be linked to the role of BtuB in facilitating kanamycin uptake.
