Evaluation of Polyhexamethylene Biguanide (PHMB) as a Disinfectant for Adenovirus [PDF]

JAMA Ophthalmology, 2013
Swimming pools can be a vector for transmission of adenovirus ocular infections. Polyhexamethylene biguanide (PHMB) is a disinfectant used in swimming pools and hot tubs.To determine whether PHMB is an effective disinfectant against ocular adenovirus serotypes at a concentration used to disinfect swimming pools and hot tubs.In vitro laboratory study ...

Variable effects of exposure to formulated microbicides on antibiotic susceptibility in firmicutes and proteobacteria [PDF]

, 2016
Microbicides are broad-spectrum antimicrobial agents that generally interact with multiple pharmacological targets. While they are widely deployed in disinfectant, antiseptic, and preservative formulations, data relating to their potential to select for ...

Effects of formulation on microbicide potency and mitigation of the development of bacterial insusceptibility [PDF]

, 2015
Risk assessments of the potential for microbicides to select for reduced bacterial susceptibility have been based largely on data generated through the exposure of bacteria to microbicides in aqueous solution.

Polyhexamethylene biguanide functionalized cationic silver nanoparticles for enhanced antimicrobial activity [PDF]

Nanoscale Research Letters, 2012
Abstract Polyhexamethylene biguanide (PHMB), a broad spectrum disinfectant against many pathogens, was used as a stabilizing ligand for the synthesis of fairly uniform silver nanoparticles. The particles formed were characterized using UV-visible spectroscopy, FTIR, dynamic light scattering, electrophoretic mobility, and TEM to measure their ...

Antimicrobial effectiveness of polyhexamethylene biguanide on Enterococcus faecalis, Staphylococcus epidermidis and Candida albicans [PDF]

Medicinski Glasnik, 2018
Aim To evaluate the antimicrobial activity of 0.2% polyhexamethilene biguanide (PHMB) in root canal models infected with Enterococcus faecalis, Candida albicans and Staphylococcus epidermidis. PHMB was compared in these tests with 2.5% NaOCl and 0.2% CHX.

Transient and sustained bacterial adaptation following repeated sublethal exposure to microbicides and a novel human antimicrobial peptide [PDF]

, 2014
Microbicides (biocides) play an important role in the prevention and treatment of infections. While there is currently little evidence for in-use treatment failures attributable to acquired reductions in microbicide susceptibility, the susceptibility of ...

Disposable negative pressure wound therapy system enhances punch graft acceptance in equine distal limb wounds

Equine Veterinary Education, EarlyView.
Summary This case series describes the use of a disposable, canister‐free negative pressure wound therapy (NPWT) system (PICO®) in combination with punch grafting for the treatment of distal limb wounds in three horses. Each horse presented with complex traumatic injuries resulting in delayed or inadequate healing of distal limb wounds.
