The use of sanitizers is essential for produce safety. However, little is known about how sanitizer efficacy varies with respect to the chemical surface properties of produce. To answer this question, the disinfection efficacies of an oxidant-based sanitizer and a new surfactant-based sanitizer for porcine rotavirus (PRV) strain OSU were examined. PRV was attached to the leaf surfaces of two ka...

Haloacetic acids (HAAs), which are formed during the disinfection of drinking waters with chlorine, are regulated by the US Environmental Protection Agency (EPA) under the Stage 1 Disinfectant/Disinfection Byproducts (D/DBP) Rule. Recently, three studies have been reported indicating that low concentrations of HAAs can also be formed during disinfection with chloramines. Methods currently appro...

STATEMENT OF PROBLEM Clinicians have used disinfection materials to remove surface contaminants during cavity preparation. It has been postulated that disinfection materials may negatively affect shear bond strength of restorative materials. If so, large numbers of restorations may be predestined for early failure with the use of a disinfection protocol. PURPOSE The purpose of this study was ...

Dental impressions disinfection is important to reduce the risk of cross contamination but this process may produce dimensional distortions. Peracetic acid is a disinfectant agent with several favorable characteristics yet underutilized in Dentistry. The aim of this paper is to compare the dimensional stability of casts obtained from addition silicone and polyether impressions that were immerse...

Background: An outbreak of Stenotrophomonas maltophilia was observed in the cultures of bronchial aspirations. After systematic culturing of the scopes and reprocessing the equipment, it turned out to be a pseudo-outbreak caused by a failure of the disinfector to sterilize ultrasound scopes, subsequently resulting in cross infection of the bronchoscopes via the connecting tubes in the dryer. Ob...

The goal of this study was to evaluate the potential of an advanced oxidation process (AOP) for microbiocidal and virucidal inactivation. The viruses chosen for this study were bacteriophage MS2, T4, and T7. In addition, Bacillus subtilis spores and Escherichia coli were studied. By using H(2)O(2) in the presence of filtered ultraviolet (UV) irradiation (UV/H(2)O(2)) to generate wavelengths abo...

BACKGROUND This study was conducted to investigate an outbreak caused by imipenem-resistant Acinetobacter baumannii (IRAB) in a medical intensive care unit (ICU) in a regional hospital. METHODS In response to an IRAB outbreak from October 2012 to February 2013, we developed several infection control measures, including an extensive review process of environmental cleaning and disinfection, an...

The aim of this study was to investigate the removal of Escherichia coli and heavy metals (Pb, Cd 2+ and Zn ) from wastewater using silver-modified clinoptilolite under different experimental conditions through the combined disinfection of pathogenic microorganisms by the silver ions and sorption of heavy metals on clinoptilolite. Batch experiments were conducted to look at the effects of initi...
