Chlorine dioxide (ClO2) is an antimicrobial agent recognized for its disinfectant properties. In this study, the sanitizing effects of ClO2 solutions against Salmonella enterica and Erwinia carotovora in water, on tomato surfaces, and between loads of tomatoes were evaluated. In water, ClO2 at 5, 10, and 20 ppm caused a > or = 5-log reduction of S. enterica within 6, 4, and 2 s, respectively. H...

Household point-of-use (POU) water treatment technologies targeted at vulnerable populations are microbiologically effective and, in small trials, improve health. We do not understand the factors that influence preference for and adoption of these technologies by target end-users. We cycled 400 rural subsistence farm households in western Kenya through three randomly ordered two-month trials of...

Intravenous injection is the most common and important action in patients admitted to the hospitals. It may cause local or systemic complications or infections. One of the cases that can be effective in prevention of infection is to use appropriate skin disinfectant solution during injection. This study is a controlled, clinical, trial one in which two disinfectant solutionsof 2% Chlorhexidine ...

Disinfectant concentration (i.e. mainly monochloramine and dichlo-ramine in the present case) at every point in a water distribution system is an important indicator of water quality. However chlorine decays in water due to reactions with various substances and thus possibly fails to disinfect the distribution system properly. In particular bioolm formed by bacteria on the walls of distribution...

BACKGROUND Norovirus, formerly known as Norwalk virus, is an important cause of gastroenteritis outbreaks in hospitals, food services, schools, and cruise ships. Infection control practices by using disinfectants to eliminate noroviruses from surfaces and environmental samples reduce the morbidity and spread of virus outbreaks. There are not many commercial disinfectants effective against norov...

Heinmets, Taylor, and Lehman (1954) treated a suspension of cells of Escherichia coli strain B/r with disifectant and found that after treatment none or only a few viable organisms were present. However, when the liquid (containing the cells which had been exposed to the disinfectant) was mixed with a solution of a metabolite in phosphate buffer and incubated overnight at 37 C, a large number o...

In orthodontics effective disinfection of pliers in short time is important. We aimed to evaluate the effectiveness of three disinfectant solutions (two quaternary ammonium compounds (Deconex, Micro10+) and one hydrogen peroxide disinfectant (Sanosil)) in orthodontic pliers’ disinfection. Nine Adams pliers were sterilized with autoclave. Pliers were contaminated with standard and hospital staph...

Li Chen: Comparison of Sporicidal Activities of Commercial Disinfectant Wipes for Surface Decontamination (Under the direction of Sally Mauriello) Digital intraoral receptors present an infection control challenge since they cannot be sterilized using traditional methods. This study evaluated the sporicidal effectiveness of CaviWipe ® , Volo ™ , and Dispatch ® wipes by directly treating spore s...

Formaldehyde is one of the most commonly used of soil disinfectants. Its efficacy against fungi in the soil is well established, but it has at least two faults. The cost of the treatment is relatively high and the time which must be allowed to elapse between treatment and seeding, if the treatment is not to injure germination, is sometimes objectionable. The principal object of the work here de...

Cryptosporidium parvum oocysts and Clostridium perfringens spores are very resistant to chlorine and other drinking-water disinfectants. Clostridium perfringens spores have been suggested as a surrogate indicator of disinfectant activity against Cryptosporidium parvum and other hardy pathogens in water. In this study, an alternative disinfectant system consisting of an electrochemically produce...
