AIMS We investigated the effectiveness of ozone (aqueous and gaseous) treatment as an alternative sanitizing technology to common conventional disinfectants in reducing the microbial contamination of both water and air. METHODS Ozone was added for 20 minutes to a well-defined volume of water and air by the system named "Ozonomatic®". The effectiveness of ozonation was determined by counting C...
UNLABELLED Dental Unit Water Systems (DUWS) are used in dental practices to provide water for cooling of dental equipment and irrigation of the oral cavity. However, they have been demonstrated to be contaminated with micro-organisms. There are currently no European Union (EU) Commission guidelines for the microbial quality of water discharged by DUWS. This study was part of an EU research prog...
Nonhealing diabetic foot ulcers (DFUs) are a common and costly complication of diabetes. Microbial burden, or "bioburden," is believed to underlie delayed healing, although little is known of those clinical factors that may influence microbial load, diversity, and/or pathogenicity. We profiled the microbiomes of neuropathic nonischemic DFUs without clinical evidence of infection in 52 individua...
A total of 300 one-day old male broilers (Cobb 500) were randomly divided into four treatment groups. The groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kGy electron-beam irradiated diets. A total of 5 replicates were performed. The chemical composition of the diet was not affected by irradiation.Irradiation doses of 5 an...
Microbial fuel cells are obtaining increased attention in wastewater treatment technology because of provision of effective treatment in presence of a low organic load through continuous electrical power supply. This paper studies the voltage reutilization performance of a microbial fuel cell using recycled wastewater from its treatment process as an anodic fuel. The experimental results show t...
BACKGROUND Bacteria have long been recognized as the primary etiology for pulpal and periapical lesions, which necessitates the elimination of bacteria from the root canal system. In primary teeth, irrigation and debridement is the main protocol required to disinfect the canal. Biomechanical preparation cannot be vigorously done on the primary teeth due to anatomical barrier such as thin and fl...
An experiment was conducted to determine whether spraying hatching eggs with electrolyzed oxidizing (EO) water would decrease eggshell microbial load and hence improve hatchability, chick quality, and broiler growth performance. Eggs were collected from a broiler breeder flock; half the eggs were sprayed with EO water and the other half were left untreated. Enterobacteriaceae and total aerobic ...
Microbiological control is very important in food industry to prevent foodborne diseases. Therefore, the present investigation was undertaken to assess the microbiological quality of fresh vegetables collected from several regions of Ropar, Punjab, India. A total of 36 vegetable samples were collected and examined for their microbial load. Contamination was mainly found in cauliflower, peas, ca...
Pre-milking teat disinfection is practised in several countries to prevent environment-related mastitis. This study was designed to prove the antimicrobial efficacy of a foaming, iodine-based teat disinfectant with five different concentrations (250; 500; 1,000; 2,000 and 3,000 ppm) against a negative control. For this purpose the split-udder design was used and within an udder two teats were d...
Current microbial methodologies to determine fish quality are laborious and have long time required to obtain results. The impediometric technique as a rapid sensitive method was used to determine the correlation between impedance detection times (IDTs) and conventional reference psychrophilic and mesophilic plate counts of fish in order to develop models for predicting the microbial quality an...
