Beyond their established hemostatic role, increasing attention has been directed toward their potential antimicrobial activity, primarily attributed to local acidification following carboxyl group dissociation. Discussing the possible implications of the antibacterial properties of OC\/ORC in veterinary surgical practice, this review critically examines the existing evidence. In vitro studies show that viable bacterial counts are significantly reduced in both Gram-positive and Gram-negative pathogens, including antibiotic-resistant strains. Historical in vivo animal models further support a reduction in bacterial recovery in contaminated tissues treated with OC. However, contemporary veterinary clinical trials specifically evaluating surgical site infection (SSI) outcomes remain limited. Documented limitations include variability in formulation, quantity-dependent degradation kinetics, and the potential for foreign body reactions when excessive material is retained. Current evidence suggests that OC may provide adjunctive antimicrobial effects under controlled experimental conditions, primarily in vitro and in standardized animal models, but these properties should be interpreted with caution, and its role should be integrated within comprehensive infection prevention strategies rather than considered a substitute for established perioperative protocols.<\/jats:p>","DOI":"10.3390\/vetsci13040349","type":"journal-article","created":{"date-parts":[[2026,4,6]],"date-time":"2026-04-06T02:06:21Z","timestamp":1775441181000},"page":"349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Considerations About the Antimicrobial Activity of Oxidized Cellulose and Oxidized Regenerated Cellulose and Their Potential Application in Veterinary Surgery"],"prefix":"10.3390","volume":"13","author":[{"given":"Riccardo","family":"Rinnovati","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Science, University of Bologna, Ozzano dell\u2019Emilia, 40064 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"D\u2019Angelo","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Science, University of Bologna, Ozzano dell\u2019Emilia, 40064 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3488-2948","authenticated-orcid":false,"given":"Angelo","family":"Peli","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47291 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Virginia","family":"Ralletti","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Science, University of Bologna, Ozzano dell\u2019Emilia, 40064 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1814-0688","authenticated-orcid":false,"given":"Federica","family":"Meistro","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Science, University of Bologna, Ozzano dell\u2019Emilia, 40064 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,3]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Medical and pharmaceutical application of oxidized cellulose","volume":"1","author":"Grabovac","year":"2020","journal-title":"Glas.
