Genetic diversity of Acanthamoeba and clinical outcome predictors in Danish patients with Acanthamoeba keratitis

Acta Ophthalmologica, Volume 104, Issue 1, Page 44-51, February 2026.
Abstract Purpose Acanthamoeba keratitis (AK) is a severe corneal infection with potential detrimental effects on visual outcome and quality of life, primarily affecting young contact lens wearers. We report Acanthamoeba genotypes, subtypes and clinical outcome from Danish patients with AK. Methods Thirty‐nine PCR‐positive AK cases diagnosed and treated

Mechanism of Polyhexamethylene Biguanide Resistance in Purpureocillium lilacinum Strains.

Biocontrol science, 2022
Purpureocillium lilacinum has been recently found to contaminate a 20% (200,000 μg/mL) aqueous solution of polyhexamethylene biguanide hydrochloride (PHMB) . We aimed to elucidate the mechanism underlying the resistance of P. lilacinum to PHMB. First, we induced the PHMB-resistant (IR) strains IFM 67050 (IR) and IFM 65838 (IR) from the type strain P ...

Pantoea agglomerans in Equine Ulcerative Keratitis: Prevalence and Comparative Efficacy of Four Topical Antiseptics

Veterinary Ophthalmology, Volume 29, Issue 1, January 2026.
ABSTRACT Objective To determine the minimal bactericidal concentration (MBC) and effective contact time of four topical antiseptics—polyhexanide, povidone‐iodine (PVP‐I), hypochlorous acid (HOCl), and N‐acetylcysteine (NAC)—against Pantoea agglomerans, a pathogen frequently isolated in equine ulcerative keratitis.
