background : dental unit waterlines (duwls) are ideal nvironment for development of microbial biofilms. microbial contamination of water in duwls is thought to be the result of biofilm formation as it could serves as a haven for pathogens. the aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of isfahan university o...
The paper presents the results regarding the electron beam irradiation of fresh Salvia Officinalis and Calendula Officinalis. Irradiation is already a well-known decontamination method, but it received less attention for medicinal plants, especially on fresh herbs. Microbial load behaviour, antioxidant activity, and enzymatic inhibition activity were measured for doses up to 50 kGy. Herbs are d...
We investigated eyewear contamination levels in the operating room to assess infection risk and inform protocol development. Microbial contamination after use was found in 37.7% of disposable and 94.9% of reusable eyewear pieces. After disinfection, 74.4% of reusable eyewear also cultured positive. Disposable eyewear may reduce intercase contamination risk. Reusable eyewear may carry ongoing bi...
A retrospective study was made of the effectiveness of an eye bank decontamination and storage method. A comparison was made between microbial cultures taken from the limbus at enucleation and from scleral remnants recovered after surgery. Organisms were isolated from the limbus of 73% of donor eyes and from 4% of remnants. Standard eye bank procedures were found to eradicate gut and skin organ...
Microbial degradation of petroleum hydrocarbons is one of the major practices in natural decontamination process. The present study investigated about the isolation of bacteria from crude oil contaminated site and gravimetric analysis of degradation in which, two bacterial isolates formed maximum clearing zone on mineral salt medium. Among these isolate S2 showed maximum growth (0.85mg/ml) and ...
BACKGROUND/AIMS Povidone-iodine (PVP -I) is applied for microbial decontamination of human eyes donated for transplantation. Concentrations and immersion times vary greatly. The effectiveness and toxicity of PVP-I were assessed for different decontamination protocols. METHODS Human donor eyes and corneas were immersed in different concentrations (5-100 mg/ml) of PVP-I for different times (2-3...
The climate crisis is one of the biggest challenges for humanity in 21st century. Production and consumption meat contributes to global warming by causing emissions climate-relevant gases. Freshly grown sprouts are part an alternative, as they less polluting but still a nutritious food. However, warm humid sprouting conditions may cause pathogenic microorganisms thrive. Decontamination methods ...
