Biofilms

Stewart P, Stoodley P, Gilbert P, McBain A, Bierman S, Dreeszen P, Thompson B, Budgell S, Ceri H.

Biofilms are nothing new to our world. They can be found in any environment that has a flow of water and a contact surface. Biofilms can be deleterious or beneficial depending on where they are found and which organisms they are comprised of. As a society, however, we most commonly associate the issue of biofilms with their related infections. Examples of these are otitis media and bacterial endocarditis, which are caused by bacteria entering a fluid filled part of the body. Accelerated Hydrogen Peroxide® (AHP®) is relatively new yet proven technology that has gained a reputation as being one of the most effective yet safe technologies on the market. In fact, two studies have been conducted using AHP highlighting its ability to kill and remove biofilms. This document will help you and decision makers to better understand what Biofilms are and the relevance of using a disinfectant capable of killing and removing them.

How Reliable are ATP Bioluminescence Meters in Assessing Decontamination of Environmental Surfaces in Healthcare Settings?

Navid Omidbakhsh, Faraz Ahmadpour, Nicole Kenny

This study evaluated the ability of four ATP bioluminescence meters to accurately determine the efficacy of disinfectants in healthcare settings. By comparing ATP bioluminescence meter results to actual cell culture tests, the researchers determined that these widely-used meters may not always provide accurate results, and that their activity may be affected by various disinfectant ingredients.

Attitudes and beliefs, not just knowledge, influence the effectiveness of environmental cleaning by environmental service workers

Matlow A.G. et al.

Environmental cleaning has been shown in numerous studies to have a direct impact in reducing Healthcare Associated Infections (HAIs). The importance of the Environmental Service Worker (ESW) in directly interrupting the chain of infection cannot be overlooked. Interventions for improving environmental cleaning often focus on education; however, little effort is given to understanding ESWs’ attitudes and beliefs towards their role and how understanding these attitudes and beliefs may help to develop strategies that further improve environmental cleaning

Assessment of Accelerated Hydrogen Peroxide® disinfectant wipes in removal of chemotherapeutic agents from hard non-porous environmental surfaces

Chemotherapy agents (also known as cytotoxic agents) are used in chemotherapy treatment to stop or slow the growth of cancer cells. However, these agents can also affect healthy cells and are known to have high toxicity which can be harmful to individuals that are not under chemotherapy treatment. In addition, chemotherapy molecules are known to be highly resistant to inactivation by chemical disinfectants. In order to protect personnel preparing chemotherapy drugs, choosing a disinfectant with the ability to cleanse or degrade chemotherapy agents is an essential aspect of the pharmacy’s/laboratory’s infection control and biosecurity program. In this investigation, Accelerated Hydrogen Peroxide® (AHP®) exhibited complete removal of all chemotherapy agents tested.

Evaluation of the Efficacy of Disinfectant Footmats for the Reduction of Bacterial Contamination on Footwear in a Large Animal Veterinary Hospital

Hornig, K.J., Burgess, B.A., Saklou, N.T., Johnson, V., Malmlov, A., Van Metre, D.C., Morley, P.S., Byers, S.R.

Infection control is critical to providing high-quality patient care as well as maintaining a safe working environment for personnel in veterinary hospitals. Many North American veterinary teaching hospitals (VTHs) utilize footbaths and footmats at entrances and key control points throughout the veterinary hospital in an endeavor to decrease trafficking of pathogenic microorganisms throughout the facility via contaminated footwear. Studies have shown that disinfectant footmats and footbaths may be helpful, but are not absolute methods, for eliminating contamination on footwear in veterinary hospital environments. While disinfectant footmats may be considered reliable in decreasing footwear contamination, the magnitude of these decreases is limited.

Infection Prevention and Control in the Dental Office, 2009

This document was developed by the Royal College of Dental Surgeons of Ontario (RCDSO) and approved by Council in November of 2009 and revised in 2010. These Guidelines, which replace those issued by RCDSO in January 2002, are significantly broader and reflect current knowledge of the transmission of infection and how to prevent and control it. The document is intended to provide all Oral Health Care Workers (OHCWs) with the knowledge to properly implement necessary infection prevention and control measures in their dental practice. This document specifically mentions the relatively new yet proven Accelerated Hydrogen Peroxide® (AHP®) technology as an effective disinfectant for non-critical devices, environmental surfaces and for the high level disinfection of semicritical devices.

Efficacy of disinfectants containing accelerated hydrogen peroxide against conidial arthrospores and isolated infective spores of Microsporum canis and Trichophyton spp.

Moriello K, Hondzo H.

Dermatophytosis (ringworm), in pets is a skin condition typically caused by fungal infections, more specifically Microsporum canis and Trichophyton spp. Disinfectants, especially sodium hypochlorite (bleach), are commonly used to kill spores not removed during the "hard" cleaning process. Bleach is commonly recommended in the fight against ringworm for its known ability to kill spores. However, it is widely recognized that bleach degrades if not used by the expiry date impacting its efficacy, requires the use of personal protective equipment (as it is a respiratory irritant and can cause damage to the skin and eyes) and has corrosive properties that are known to cause damage to fabrics and surfaces. As a result, a comprehensive analysis was undertaken to determine if Accelerated Hydrogen Peroxide® (AHP®) would be a suitable alternative to sodium hypochlorite.

Quality Control is Indispensable for Automated Dilution Systems with Accelerated Hydrogen Peroxide

O’Neill C. et al.

Accelerated Hydrogen Peroxide® (AHP®) is a patented synergistic blend of commonly used, safe ingredients that when combined with low levels of hydrogen peroxide dramatically increase its germicidal potency and cleaning performance. To ensure maximum efficacy, AHP concentrated products can be diluted with automated dilution control systems. However, just as we wouldn’t run our automobiles without regular oil changes and tire rotations, so to we shouldn’t operate these systems without regularly scheduled preventative maintenance. This evaluation focused on an AHP disinfectant and its associated dilution system to emphasize the importance of performing quality checks on other hospital grade disinfectants that are diluted and dispensed from automated control systems.

Tanning bed hygiene: Microbes found on tanning beds present a potential health risk

Russak JE, Rigel DS.

On an average day in the Unites States, more than 1 million people use tanning salons. However, dermatologists say you may be getting more than just a tan while using salon beds. Studies show that bacteria and viruses can lurk inside tanning beds, including the dreaded herpes virus. Currently, there is little uniformity in sanitary guidelines for tanning salons. Although cleanliness is encouraged, most states have no monitoring or enforcement methods

The National White-Nose Syndrome Decontamination Protocol

Pseudogymnoascus destructans (Pd) is a fungus that causes White-Nose Syndrome (WNS) in hibernating bats. The fungus grows on the bats nose, wings and ears and is highly transmissible between bats and also by human-assisted transmission from cave to cave. Caving is becoming more popular, either from a scientific point of view or recreationally. The fungus is causing severe mortality within bat populations across the United States and eastern Canada. It was estimated in 2012 that 5.7-.6.7 million bats have died because of WNS, some species seeing mortality of up to 98%. This is raising concern over potential impacts this may have on ecosystems, such as insect control, pollination or seed dispersal. With no known cure, biosecurity must play a critical role in prevention.
