The frequent confusion of these infections may justify the use of a rapidly acting broad-spectrum antibiotic treatment. Methods: This study investigated the bactericidal kinetics of the neomycin-polymyxin B-nystatin (NPN) combination compared to those of two reference antibiotics (clindamycin and metronidazole) against 22 bacteria commonly implicated in AV and BV. Results: NPN exhibited bactericidal activity against the aerobic Gram-positive bacteria, with particularly high bactericidal activity being observed against streptococci, S. aureus, and C. amycolatum after 1 h at low dilutions and after 4 h for all dilutions. Enterococci were less sensitive to NPN. Clindamycin demonstrated poor rapid bactericidal activity against all Gram-positive bacteria tested. NPN manifested high bactericidal activity against all aerobic Gram-negative bacteria tested, whereas clindamycin showed bactericidal activity only after 4 h at a 1\/2 dilution. With respect to the four anaerobic strains tested, NPN demonstrated high bactericidal activity at all tested dilutions with concentration-dependent effects. Metronidazole exhibited lower or no rapid bactericidal activity. Conclusions: These results suggest that NPN has very fast bactericidal action against the main bacteria involved in AV and BV compared to clindamycin and metronidazole, highlighting its potential in managing bacterial vaginal infections.<\/jats:p>","DOI":"10.3390\/ph18030340","type":"journal-article","created":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T05:13:58Z","timestamp":1740633238000},"page":"340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["In Vitro Bactericidal Activity of a Neomycin-Polymyxin B-Nystatin Combination Compared to Metronidazole and Clindamycin Against the Main Bacteria Involved in Bacterial Vaginosis and Aerobic Vaginitis"],"prefix":"10.3390","volume":"18","author":[{"given":"Catherine","family":"Feuillolay","sequence":"first","affiliation":[{"name":"ACM Pharma Fonderephar, 35 Chemin des Mara\u00eechers, 31062 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvie","family":"Salvatico","sequence":"additional","affiliation":[{"name":"ACM Pharma Fonderephar, 35 Chemin des Mara\u00eechers, 31062 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"Escola","sequence":"additional","affiliation":[{"name":"Laboratoire Innotech International, Groupe Innothera, 22 Avenue Aristide Briand, 94110 Arcueil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4285-0519","authenticated-orcid":false,"given":"Barbara","family":"Quioc-Salomon","sequence":"additional","affiliation":[{"name":"Laboratoire Innotech International, Groupe Innothera, 22 Avenue Aristide Briand, 94110 Arcueil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fr\u00e9d\u00e9ric","family":"Carrois","sequence":"additional","affiliation":[{"name":"Laboratoire Innotech International, Groupe Innothera, 22 Avenue Aristide Briand, 94110 Arcueil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Roques","sequence":"additional","affiliation":[{"name":"Laboratoire de G\u00e9nie Chimique UMR 5503 (CNRS, INPT, UPS), Universit\u00e9 de Toulouse, 35 Chemin des Mara\u00eechers, 31062 Toulouse Cedex 9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"ref_1","first-page":"1095","article-title":"Diagnosis of vaginitis","volume":"62","author":"Egan","year":"2000","journal-title":"Am.
