Effects of stabilized hypochlorous acid on oral biofilm bacteria

Microbe(s): NCBI - Oral Biofilm Bacteria

ABSTRACT - Full Text PDF

Low concentrations of HOCl (5 ppm), stabilized with 0.14% or 2% HAc, significantly reduced viability in multi-species biofilms representing supra- and sub-gingival oral communities, after 5 min, without causing erosion of HA surfaces. No equivalent antimicrobial effect was seen for CHX. Gram-positive and Gram-negative bacteria showed no significant differential suceptibility to stabilized...

Effectiveness of Hypochlorous Acid to Reduce the Biofilms on Titanium Alloy Surfaces in Vitro

Microbe(s): International Journal of Molecular Sciences - E. coli and P. gingivalis

ABSTRACT - Full Text PDF

Within the limitations of this in vitro model, HOCl is effective for cleaning biofilm-contaminated implant surfaces and has the potential to be an antiseptic for peri-implantitis treatment. These results suggest that the efficacy of HOCl is equivalent to NaOCl and CHX. The concentration of HOCl (0.018%) was lower than those for NaOCl (1.3%) and CHX (0.2%) but still showed efficacy against the...

Hypochlorous acid: an ideal wound care agent with powerful microbicidal, antibiofilm, and wound healing potency

Microbe(s): Wounds 26 (2014): 342-350

ABSTRACT - Full Text PDF

Introduction. Chronic wounds and the infections associated with them are responsible for a considerable escalation in morbidity and the cost of health care. Infection and cellular activation and the relation between cells are 2 critical factors in wound healing. Since chronic wounds offer ideal conditions for infection and biofilm production, good wound care strategies are critical for wound...

Efficacy of acidic and basic electrolyzed water in eradicating Staphylococcus aureus biofilm

Microbe(s): Canadian Journal of Microbiology 58.4 (2012): 448-454

ABSTRACT - Full Text PDF

Staphylococcus aureus is a major pathogen. It can form biofilm on the surfaces of medical devices and food equipment, which makes it more difficult to eradicate. To develop a novel method to eradicate S. aureus biofilm, the effects of electrolyzed water on removing and killing S. aureus biofilm were investigated in this study. By using a biofilm biomass assay with safranin staining and...

Microbe(s): Journal of Food Protection 68.7 (2005): 1375-1380

ABSTRACT - Full Text PDF

Biofilms are potential sources of contamination to food in processing plants, because they frequently survive sanitizer treatments during cleaning. The objective of this research was to investigate the combined use of alkaline and acidic electrolyzed (EO) water in the inactivation of Listeria monocytogenes biofilms on stainless steel surfaces. Biofilms were grown on rectangular stainless steel...

Antiseptic Effect of Slightly Acidic Electrolyzed Water on Dental Unit Water Systems

Microbe(s): The Bulletin of Tokyo Dental College 55.2 (2014): 77-86

ABSTRACT - Full Text PDF

Biofilm formation in dental unit water systems (DUWSs) can contaminate water from three-in-one syringes, air rotors, and low-speed handpieces. This may serve as a potential source of infection for dentists, dental staff, and patients, so these systems must be sterilized. Becaslightly acidic electrolyzed water (SAEW) is often used as a disinfectant for food, the aim of this study was to...
