The chlorophenols have disinfectant-like tastes, detectable in water in concentrations ranging from 0.04 parts per billion (ppb) for 2, 6-dichlorophenol to 30 ppb for pentachlorophenol (PCP). The chlorophenols are soluble in most organic solvents and are slightly soluble in water. Chlorocresols share the disinfectantchemical taste of the chlorophenols, and may have even lower taste threshold va...

Sunshine is the Best Disinfectant Once again, Pennsylvania has made national headlines as a pioneer in the public reporting of information related to medical quality. Now with the release of PHC4's report on hospitalacquired infections (HAI) in Pennsylvania, the state has focused a very bright light on a critical health care issue with national policy implications. Indeed, Pennsylvania is the f...

Despite recently revived interest in gaseous disinfection or sterilization, only two compounds, formaldehyde and ethylene oxide, have been used to any great extent for this purpose. As discussed by Phillips (1957) in a review of gaseous sterilization, several other compounds have been mentioned in the literature as possessing bactericidal properties in the vapor state but have been put to littl...

Drinking water disinfection was shown to be an important public health measure around the turn of the century. In the United States, it was perhaps the single most important factor in controlling typhoid fever, a waterborne disease that was rampant throughout the world during the last century. It may also be assumed that disinfection was important in limiting the number of cases of other diseas...

This study evaluated the effect of a 2% chlorhexidine-based disinfectant (CHX) on the short-term resin-dentin bond strength of a self-etch adhesive system to human dentin with different mineral contents. Dentinal mineralization was tested at 4 levels (sound, and after 2, 4, or 8 days of demineralization-remineralization cycles) and disinfectant at 2 levels [deionized water (DW, negative control...

egionnaires’ disease is caused by Legionella bacteria, which colonize 12–70% of hospital water systems (Lin et al, 1998b). Of the Legionnaires’ disease cases reported to the Centers for Disease Control and Prevention (CDC), 25–45% were hospital-acquired (Benin et al, 2002). Legionella and other opportunistic pathogens colonize water systems; cause pneumonia, wound, and bloodstream infections in...

The aim of this study was evaluation an organic germicide (Aquagerm) histological affects on Rainbow trout (Oncorhynchus mykiss) vital tissues. This new disinfectant is an aquatic antiseptic and mixed-oxidant disinfectant which is produced for the first time in Iran. This new product mechanism is based on oxidant properties of pro-sulphate which attack crucial structures of pathogens. In this s...

abstract       background and aim: dimensional changes of the impression materials after disinfection is a serious problem in dentistry which could fail the treatment. the aim of this study is to determine the effect of three disinfectants:2% deconex,5.25% sodium hypochlorite and nanosil d2 ,on dimensional changes of bayer alginate.       materials and methods: this experimental study was condu...

Most infants admitted to premature baby or neonatal surgical units are nursed in incubators during part of their stay in hospital. There are many advantages of nursing these infants in incubators, but there is also one great disadvantage, the danger of bacterial colonization and contamination inside the incubator. The temperature inside the incubator approaches that of the body and many of thes...
