PURPOSE A recent increase in Acanthamoeba keratitis (AK) cases has been associated with Complete MoisturePlus, although many cases used other solutions. Complete MoisturePlus contains taurine and hydroxypropyl methylcellulose, unlike other multipurpose solutions (MPSs). The purpose of this study is to (1) determine contact lens solution efficacy against recent clinical and tap water Acanthamoeb...

Irrigating wounds with tap water does not increase colonisation, but controlled studies are required for further evidence. Microbial colonisation was assessed in skin wounds, before and after irrigation with tap water, and was compared with irrigation using 0·9% sodium chloride sterile solution. The study included 120 subjects with chronic, traumatic, vascular, pressure or neuropathic wounds. A...

The continuous expansion of urban areas is associated with increased water demand, both for domestic and non-domestic uses. To cover this additional demand, centralised infrastructure, such as water supply and distribution networks tend to become more and more complicated and are eventually over-extended with adverse effects on their reliability. To address this, there exist two main strategies...

Legionella spp. are ubiquitous in aquatic habitats and water distribution systems, including dental unit waterlines (DUWLs). The aim of the present study was to determine the prevalence of Legionella in DUWLs and tap water samples using PMA-qPCR and standard culture methods. The total viable counts (TVCs) of aerobic heterotrophic bacteria in the samples were also determined. Legionella spp. wer...

Previous work suggests that δ(18)O values of human hair can be used to constrain the region-of-origin of unknown individuals, but robust assessments of uncertainties in this method are lacking. Here we assess one source of uncertainty - temporal variation in the δ(18)O value of drinking water - using a monthly tap water survey of δ(18)O to develop geospatial models (i.e., maps) of the intra-ann...

Background and objectives: Stenotrophomonas maltophilia is one of the pathogenic bacteria originated from water and is released through water. This study was conducted with the aim of isolating Stenotrophomonas maltophilia from water and water tap in the environment and investigating the existence of rpfF gene and its relation with biofilm formation, motility and the extracellular enzymes of

BACKGROUND Tap water scalds can be devastating and are entirely preventable. This topic has received notable attention in Canada in recent years, with a national campaign in 2001 directed at parents recommending that they lower the water temperature of their home water heater. This campaign has been evaluated and reported as a successful population-based intervention. OBJECTIVES The present s...

Stable isotopes in water (e.g., δ2H and δ18O) are important indicators of hydrological and ecological patterns and processes. Tap water can reflect integrated features of regional hydrological processes and human activities. China is a large country with significant meteorological and geographical variations. This report presents the first national-scale survey of Stable Isotopes in Tap Water (...

The growth kinetics of Flavobacterium sp. strain S12 specialized in the utilization of glycerol, and a number of oligo- and polysaccharides were determined in batch-culture experiments at 15 degrees C in pasteurized tap water supplied with very low amounts of substrates. Kss for the growth on maltotriose, maltotetraose, maltopentaose, and maltohexaose were 0.03 microM or less and below those fo...

OBJECTIVE To estimate the associations of acidity and concentration of selected minerals in household tap water with the risk of type 1 diabetes. RESEARCH DESIGN AND METHODS We designed a population-based case-control study with 64 cases of type 1 diabetes and 250 randomly selected control subjects. Acidity, color, and mineral content were measured in tap water from each participant's househo...
