This study presents the first report of\n                      <jats:italic toggle=\"yes\">E. marmotae<\/jats:italic>\n                      isolation from\n                      <jats:italic toggle=\"yes\">Berylmys bowersi<\/jats:italic>\n                      in Guizhou province. We conducted genetic, biochemical, and antibiotic resistance analyses on four isolates, designated as S2-2, S2-4, S2-5, and S2-6. Phylogenetic analysis based on 16S rRNA sequences revealed over 99.5% homology with\n                      <jats:italic toggle=\"yes\">E. marmotae<\/jats:italic>\n                      , while pulsed-field gel electrophoresis and whole-genome sequencing confirmed genetic similarity. Gene annotation highlighted the presence of 137 virulence factors and five antibiotic resistance mechanisms, including resistance to fluoroquinolones and tetracyclines. Resistance phenotypes of 35 antibiotics showed resistance to penicillin, erythromycin, rifampin, and co-trimoxazole. The strains exhibited significant biochemical diversity, with positive results for several fermentation pathways and negative motility assays. This study underscores the emerging zoonotic potential of\n                      <jats:italic toggle=\"yes\">E. marmotae<\/jats:italic>\n                      and its associated health risks in wildlife and humans.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        The isolation of\n                        <jats:italic toggle=\"yes\">Escherichia marmotae<\/jats:italic>\n                        from\n                        <jats:italic toggle=\"yes\">Berylmys bowersi<\/jats:italic>\n                        represents a novel discovery, expanding the known host range of this bacterium.
