This study aimed to isolate and characterize a lytic bacteriophage with therapeutic potential against MDR P. mirabilis. Using the clinical MDR P. mirabilis strain Pm 07 as host, a bacteriophage, vB_Pmc_P-07 (P-07), was successfully isolated from fecal and sewage samples via an enrichment protocol. Phage P-07 forms plaques surrounded by a distinct translucent \u201chalo,\u201d suggesting the production of depolymerase. It achieved high titers of up to 1.40 \u00d7 108 PFU\/mL and exhibited a narrow host range, high stability across a broad range of temperatures (40\u201360 \u00b0C) and pH (4\u201312), as well as considerable anti-biofilm activity. An optimal multiplicity of infection (MOI) of 0.001 was determined. Whole-genome sequencing revealed a linear double-stranded DNA genome of 58,582 bp with a GC content of 46.91%, encoding 63 open reading frames. Crucially, no virulence or antibiotic resistance genes were detected, supporting its safety profile. Phylogenetic analysis classified P-07 within the Casjensviridae family, closely related to phages PM87 and pPM01. These findings indicate that phage P-07 is a novel, safe, and effective lytic phage with strong potential as a biocontrol agent against biofilm-forming MDR P. mirabilis in swine.<\/jats:p>","DOI":"10.3390\/v17111419","type":"journal-article","created":{"date-parts":[[2025,10,27]],"date-time":"2025-10-27T02:50:48Z","timestamp":1761533448000},"page":"1419","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Genomic and Biological Characterization of a Novel Proteus mirabilis Phage with Anti-Biofilm Activity"],"prefix":"10.3390","volume":"17","author":[{"given":"Yan","family":"Liang","sequence":"first","affiliation":[{"name":"College of Animal Science and Technology, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nana","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shenghui","family":"Wan","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanfang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuwan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Food and Bioengineering, Henan University of Science and Technology, Luoyang 471023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2649-4144","authenticated-orcid":false,"given":"Yonggang","family":"Qu","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5575","DOI":"10.1099\/ijsem.0.001485","article-title":"Genome-based phylogeny and taxonomy of the \u2018Enterobacteriales\u2019: Proposal for Enterobacterales ord. nov. divided into the families Enterobacteriaceae, Erwiniaceae fam. nov., Pectobacteriaceae fam. nov., Yersiniaceae fam. nov., Hafniaceae fam. nov., Morganellaceae fam. nov., and Budviciaceae fam. nov","volume":"66","author":"Adeolu","year":"2016","journal-title":"Int.
