The aim of this study was to assess the genotoxic potential of a dextrin\u2013polyvinyl alcohol\u2013iodine (D\/PVA\/I-1) complex in accordance with OECD guidelines. Genotoxicity was evaluated in vitro using two complementary assays: the mammalian cell micronucleus test (OECD TG 487) in L5178Y TK+\/\u2212 cells and the bacterial reverse mutation assay (Ames test, OECD TG 471) using Salmonella typhimurium strains TA98, TA100, TA1535, TA1537 and Escherichia coli WP2 uvrA, both in the presence and absence of metabolic activation (S9). In the micronucleus assay, no statistically significant increase in micronucleus frequency was observed at concentrations ranging from 0.039 to 0.625 mg\/mL compared with the negative control. In the Ames test, no increase in revertant colony numbers was detected in any tested bacterial strain at concentrations up to 1250 \u03bcg\/plate. At higher concentrations, pronounced cytotoxic and bactericidal effects were observed without evidence of mutagenic activity. Overall, the results demonstrate that the D\/PVA\/I-1 complex does not exhibit genotoxic or mutagenic potential under the tested in vitro conditions, indicating a favorable genetic safety profile and supporting further preclinical evaluation for potential biomedical applications.<\/jats:p>","DOI":"10.3390\/polym18141771","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T12:00:17Z","timestamp":1784548817000},"page":"1771","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["In Vitro Measurement of Genotoxicity of Antimicrobial Dextrin\u2013Polyvinyl Alcohol\u2013Iodine Complex"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3100-6523","authenticated-orcid":false,"given":"Tamara","family":"Bukeyeva","sequence":"first","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9621-3534","authenticated-orcid":false,"given":"Seitzhan","family":"Turganbay","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Kazakh National Women\u2019s Teacher Training University, Almaty 050000, Kazakhstan"},{"name":"Petroleum Engineering Institute \u201cOne Belt, One Road\u201d, Kazakh-British Technical University, Almaty 050000, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8610-7321","authenticated-orcid":false,"given":"Ardak","family":"Jumagaziyeva","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7428-0074","authenticated-orcid":false,"given":"Zhanar","family":"Iskakbayeva","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saltanat","family":"Jumabayeva","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7791-3145","authenticated-orcid":false,"given":"Anar","family":"Seysembekova","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingcheng","family":"Hao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Colloid and Interface Chemistry, Ministry of Education, Shandong University, Jinan 250100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana","family":"Askarova","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alina","family":"Sabdanbekova","sequence":"additional","affiliation":[{"name":"Department of Immunology and Virology, Kyrgyz State Medical Academy, Bishkek 720020, Kyrgyzstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dokturbek","family":"Adambekov","sequence":"additional","affiliation":[{"name":"Department of Immunology and Virology, Kyrgyz State Medical Academy, Bishkek 720020, Kyrgyzstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amir","family":"Azembayev","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaukhar","family":"Askhatkyzy","sequence":"additional","affiliation":[{"name":"JSC \u201cScientific Center for Anti-Infective Drugs\u201d, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1016\/j.ijsu.2017.06.073","article-title":"Povidone iodine in wound healing: A review of current concepts and practices","volume":"44","author":"Bigliardi","year":"2017","journal-title":"Int.
