The effects of high-intensity pulsed-light emissions of high or low UV content on the survival of predetermined populations of Listeria monocytogenes, Escherichia coli, Salmonella enteritidis, Pseudomonas aeruginosa, Bacillus cereus, and Staphylococcus aureus were investigated. Bacterial cultures were seeded separately on the surface of tryptone soya-yeast extract agar and were reduced by up to 2 or 6 log10 orders with 200 light pulses (pulse duration, approximately 100 ns) of low or high UV content, respectively (P < 0.001).  (+info)

Disinfection of upper gastrointestinal fibreoptic endoscopy equipment: an evaluation of a cetrimide chlorhexidine solution and glutaraldehyde. (2/846)

There is little information available on the bacteriological contamination of upper gastrointestinal fibreoptic endoscopes during routine use and the effects of 'disinfecting solutions'. A bacteriological evaluation was therefore made of cleaning an endoscope and its ancillary equipment with (1) water, (2) an aqueous solution of 1% cetrimide with 0.1% chlorhexidine, and (3) activated aqueous 2% glutaraldehyde. All equipment, but particularly the endoscope itself, was found to be heavily contaminated after use with a wide variety of organisms of which 53% were Gram positive. Cleaning the endoscope and ancillary equipment with water and the cetrimide/chlorhexidine solution alone or in combination was inadequate to produce disinfection but immersion in glutaraldehyde for two minutes consistently produced sterile cultures with our sampling technique. A rapid and simple method for disinfection of endoscopic equipment is therefore recommended and we think this is especially suitable for busy endoscopy units.  (+info)

A test for 'hygienic' hand disinfection. (3/846)

A standardised test procedure is described in which finger-tips are inoculated with broth cultures of organisms (Staphylococcus aureus, Staphyloccocus saprophyticus, Escherichia coli, and Pseudomonas aeruginosa): counts are made from washings of hands after disinfection with various antiseptic-detergents, alcoholic solutions, or unmedicated soap. 70% alcohol, with or without chlorhexidine, was the most effective preparation. The two antiseptic detergents showed variable results, but against Gram-negative bacilli neither was significantly more effective than plain soap. Some tests were also made on the death rate of organisms dried on the skin without disinfection.  (+info)

Drinking water disinfection byproducts: review and approach to toxicity evaluation. (4/846)

There is widespread potential for human exposure to disinfection byproducts (DBPs) in drinking water because everyone drinks, bathes, cooks, and cleans with water. The need for clean and safe water led the U.S. Congress to pass the Safe Drinking Water Act more than 20 years ago in 1974. In 1976, chloroform, a trihalomethane (THM) and a principal DBP, was shown to be carcinogenic in rodents. This prompted the U.S. Environmental Protection Agency (U.S. EPA) in 1979 to develop a drinking water rule that would provide guidance on the levels of THMs allowed in drinking water. Further concern was raised by epidemiology studies suggesting a weak association between the consumption of chlorinated drinking water and the occurrence of bladder, colon, and rectal cancer. In 1992 the U.S. EPA initiated a negotiated rulemaking to evaluate the need for additional controls for microbial pathogens and DBPs. The goal was to develop an approach that would reduce the level of exposure from disinfectants and DBPs without undermining the control of microbial pathogens. The product of these deliberations was a proposed stage 1 DBP rule. It was agreed that additional information was necessary on how to optimize the use of disinfectants while maintaining control of pathogens before further controls to reduce exposure beyond stage 1 were warranted. In response to this need, the U.S. EPA developed a 5-year research plan to support the development of the longer term rules to control microbial pathogens and DBPs. A considerable body of toxicologic data has been developed on DBPs that occur in the drinking water, but the main emphasis has been on THMs. Given the complexity of the problem and the need for additional data to support the drinking water DBP rules, the U.S. EPA, the National Institute of Environmental Health Sciences, and the U.S. Army are working together to develop a comprehensive biologic and mechanistic DBP database. Selected DBPs will be tested using 2-year toxicity and carcinogenicity studies in standard rodent models; transgenic mouse models and small fish models; in vitro mechanistic and toxicokinetic studies; and reproductive, immunotoxicity, and developmental studies. The goal is to create a toxicity database that reflects a wide range of DBPs resulting from different disinfection practices. This paper describes the approach developed by these agencies to provide the information needed to make scientifically based regulatory decisions.  (+info)

Chlorine inactivation of Escherichia coli O157:H7. (5/846)

We analyzed isolates of Escherichia coli O157:H7 (which has recently caused waterborne outbreaks) and wild-type E. coli to determine their sensitivity to chlorination. Both pathogenic and nonpathogenic strains were significantly reduced within 1 minute of exposure to free chlorine. Results indicate that chlorine levels typically maintained in water systems are sufficient to inactivate these organisms.  (+info)

Response of pathogenic Vibrio species to high hydrostatic pressure. (6/846)

Vibrio parahaemolyticus ATCC 17802, Vibrio vulnificus ATCC 27562, Vibrio cholerae O:1 ATCC 14035, Vibrio cholerae non-O:1 ATCC 14547, Vibrio hollisae ATCC 33564, and Vibrio mimicus ATCC 33653 were treated with 200 to 300 MPa for 5 to 15 min at 25 degrees C. High hydrostatic pressure inactivated all strains of pathogenic Vibrio without triggering a viable but nonculturable (VBNC) state; however, cells already existing in a VBNC state appeared to possess greater pressure resistance.  (+info)

Bronchoscopy-related infections and pseudoinfections--New York, 1996 and 1998. (7/846)

Bronchoscopy is a useful diagnostic technique that can be performed safely by trained specialists when the bronchoscopes in both inpatient and ambulatory-care settings are reprocessed properly to prevent transmission of infection. The New York State Department of Health received reports of three clusters of culture-positive bronchoscopy specimens obtained in 1996 and 1998 from patients at local health-care facilities. This report summarizes the results of investigations of these clusters, which indicated involvement of Mycobacterium tuberculosis, M. intracellulare, or imipenem-resistant Pseudomonas aeruginosa. Between patient uses, bronchoscopes had been cleaned, visually inspected, leak tested, and processed by STERIS System 1 processors (STERIS, Mentor, Ohio).  (+info)

Evaluation of disinfection and sterilization of reusable angioscopes with the duck hepatitis B model. (8/846)

PURPOSE: Nosocomial transmission of viral hepatitis and retrovirus infection has been reported. The expected risk is greatest for the hepatitis B virus (HBV). The duck HBV (DHBV) has similar biologic and structural characteristics to HBV and has been adopted as a suitable model for disinfectant testing. METHODS: Angioscopic examination of the external jugular vein was performed on DHBV-infected ducks. After use, the instrument was air dried for 3 minutes. Samples were obtained by flushing the channel with 5 mL of phosphate buffered saline solution. The samples were collected immediately after drying (control), after flushing with 5 mL of water, after glutaraldehyde disinfection for 5, 10, and 20 minutes, and after ethylene oxide gas sterilization. Angioscopes were either precleaned or uncleaned before disinfection/sterilization. Residual infectivity was assessed with inoculation of samples into the peritoneal cavity of day-old ducks (n = 231). RESULTS: DNA analysis results of liver samples showed that all 38 control ducks became infected. The frequency of DHBV infection was reduced to 93% (14 of 15) by flushing the angioscope with 5 mL of sterile water. No transmission occurred after the use of any of the properly precleaned and disinfected/sterilized angioscopes. However, after the use of the uncleaned angioscopes, the transmission rate was 90% (9 of 10) and 70% (7 of 10) after 5 and 10 minutes of contact time, respectively, in 2% glutaraldehyde. Even after the recommended 20 minutes of contact time, there was still 6% (2 of 35) transmission. After ethylene oxide sterilization, two of the recipient ducklings (2 of 35) were infected with DHBV. CONCLUSION: There was no disease transmission after reuse of disposable angioscopes adequately cleaned before disinfection or sterilization. However, if the angioscopes are inadequately cleaned, DHBV can survive despite glutaraldehyde disinfection or ethylene oxide sterilization. This contrasts with previous in vitro and in vivo data with solid surgical instruments. It is postulated that the presence of a narrow lumen or residual protein shielding within the lumen may compromise effective inactivation of hepadnaviruses on angioscopes, with the potential risk for patient-to-patient transmission.  (+info)

The first Ozone Pipeline Disinfection System (PDS) has now been operating for two years and a further two units were delivered to Sydney Water in March 2014. The trailers to date have proven to be reliable with no failures in service and have achieved their intended purpose. For a customer of the utility, the use of the ozone process is cost effective and reliable in achieving disinfection. When using the superchlorination process there may be a potential risk of customers accidently receiving highly chlorinated water. The Ozone process eliminates this risk. If Ozonated water were to be accidently released to customers the risk would be negligible as ozone decays very quickly. Download to find out more ...
Unlike most chemical disinfectants, ultraviolet disinfection does not produce any toxic byproducts like those produced when chlorine is used as a disinfectant in drinking water applications. Furthermore, UV does not alter the taste of the water or introduce odor, nor does it remove any beneficial mineral content. UV disinfection is also extremely safe as there are no toxic chemicals to transport or store as in the case of chlorine. There are also no residuals produced by the UV disinfection process. This lends well to disinfection in the food and beverage industries as well as air disinfection. In this era of environmental consciousness, Ultraviolet Disinfection is finding its way into more and more applications due to it being a green technology that helps to preserve the natural environment. ...
Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic character of the UV disinfection configuration.

This work aims to describe the shift in microbial diversity and community structure within a hospital hot-water system upon the introduction of on-site monochloramine disinfection. Drinking water distribution systems, including premise plumbing of buildings, contain a diverse microbiological population. Proposed ASHRAE Legionella standards will likely result in a significant increase in the use of on-site water disinfection systems in a diverse array of buildings, with unknown impact on the microbial ecology of the premise plumbing. To date, the majority of on-site disinfection systems have been installed in hospitals, creating a valuable testing ground to observe the impact of on-site disinfection systems on microbial ecology prior to wide application. To gain a better understanding of the shift in microbial ecology introduced by monochloramine disinfection, this study will characterize the microbial populations within the hospital system by sequencing of the 16S ribosomal gene isolated from ...

The phage induced disinfection rates of Escherichia coli K-12 MG1655 in the presence of coliphage Ec2 were determined under a wide range of phage and bacterial concentrations. These rates were elucidated to determine if phages could be used in water and wastewater treatment systems as a biological based disinfectant. Disinfection rates ranging from 0.13 ± 0.1 to 2.03 ± 0.1 h⁻¹ were observed for E. coli K12. A multiple linear regression model was used to explain the variance in the disinfection rates, and this model demonstrated an interaction effect between the initial phage and bacterial concentrations. Furthermore, the results were modeled with particle aggregation theory, which over predicted the disinfection rates at higher phage and bacterial concentrations, suggesting additional interactions. Finally, the observed and predicted disinfection rates were used to determine additional design parameters. The results suggested that a phage based disinfection process may be suitable for the ...

A method which enhances a disinfection process by using a catalyst which increases in effective surface area during the process. Also disclosed are contact lens disinfecting systems which are designed to maintain a high concentration of hydrogen peroxide solution for a longer period of time before increasing the overall surface area of catalyst exposed to the hydrogen peroxide solution. The devices utilize pressure from expanding oxygen generated within the system through use of a small catalyst, or through exposure of only a small portion of a large catalyst, to control deployment of the large catalyst for completing disproportionation of the hydrogen peroxide.
There is a raise in concern as shown in recent studies, that when it comes to the traditional wastewater disinfection methods such as chlorination and ozonation, there is a formation of health related disinfection by-products such as trihalomethanes and haloacetic acids that can have carcinogenic tendencies. One of the alternative methods available for commercialization in the near future are advanced oxidation processes, which use semiconductor photochemistry in disinfection. The most effective photo catalyst for these disinfection purposes is TiO2, which is a non-toxic substance that is widely used in products like toothpastes and cosmetics. Traditionally these methods are added as a tertiary or final stage of wastewater treatment, which renders them an additional cost to wastewater systems. In this research, heterogeneous photo catalysis of TiO2 is combined with a pressure driven nanofiltration system, in order to integrate disinfection into a water quality solution and avoid the separation ...
More than one third of the population in rural and in peri-urban areas of developing countries has no access to sufficient or clean drinking water free of pathogens. Thus, waterborne gastroenteritis remains a major infrastructural and public health problem particularly, as effective treatment (filtration, chlorination, treatments plants) is often beyond financial means or environmental resources used for water purification (fire-boiling, burning carbon-based fuels) become scarce in those communities. In this context solar disinfection of drinking water is especially appealing using a combination of irradiation by direct sunlight and solar heating to kill the water-borne patho¬gens in contaminated drinking water. To date, the efficacy of the SODIS technology as a home-based, low-cost intervention to provide safe drinking water in low income countries is well established, and a large-scale promotion and dissemination program is under way in seven Latin American countries. The principal objective ...
Antiseptic preparations used repeatedly to disinfect the skin caused a reduction in yield of resident flora to a low equilibrium level beyond which further reduction did not occur. This equilibrium varied with the antiseptic preparation used. In a comparison of three preparations, the lowest equilibrium level was obtained with 95% ethyl alcohol. The further reduction in yield of skin bacteria on using alcohol after repeated disinfection with an antiseptic detergent preparation (two-phase disinfection) was not paralleled by a further reduction when the preparations used in the two phases were reversed, the antiseptic detergent being used after repeated disinfection with ethyl alcohol. Two-phase disinfection was therefore seen to be due to further reduction in skin bacteria from the low equilibrium obtained with the antiseptic detergent to the lower level obtainable by alcohol disinfection. When repeated disinfection to equilibrium with alcohol was followed by a second-phase handwash with a ...

There are many benefits to treating your water with ultraviolet disinfection. For example, avoiding harsh chemicals like bleach and chlorine. And reducing your carbon footprint. UV Disinfection is a safe, low maintenance way to kill bacteria in your treated water without changing the taste, color or smell.
The influence of disinfection by-products (DBPs) on the operation and design of water treatment plants has been increasing since the early studies by Rook on trihalomethanes (THMs) (Stevens, 1977). Work conducted in the 1980s identified the existence of nonvolatile halogenated organics (non-THM organics), of which the majority produced by chlorination were haloacetic acids (HAAs), within the HAAs, dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) were the dominant members. Concern over potential health effect led the U.S. Environmental Protection Agency (USEPA) to set a maximum contaminant level (MCL) for total THMs and HAAs. The disinfectant/disinfection by-product rule (D-DBP Rule) currently proposed by the USEPA will lower the MCL for THMs and HAAs. Past and pending DBP regulations have provided a momentum to seek a better understanding of how these compounds are formed as well as how their production can be controlled. Drinking water utilities are preparing for these major

Disinfection of water is mandatory for swimming pools. Most of them use Chlorine or its derivates for that purpose. When entering the pool bathers bring substances such as sweat, hairs and cosmetics that react with disinfectants and form disinfection by-products (DBPs) which are known to be harmful for human health. In order to avoid the formation of these undesirable products new technologies for pool water treatment must be developed or alternatively a control system of the DBPs in the pool. The most important DBPs and their precursors are organic. Nanofiltration (NF) comes up as a possible solution for the problem as it is capable of rejecting organic matter. A nanofiltration filtration plant was installed in an indoor pool in Germany. The existed pool water treatment included flocculation, powdered activated carbon adsorption and ultrafiltration. During this study a branch current was treated by the new NF plant. The nanofiltration plant treated 0.3% of the global recycle flow, meaning ...

An understanding of the methods and mechanics of sterilization and disinfection is necessary to prevent bacterial cross-contamination. Since sterilization of impressions is not possible, because of the high temperature and time needed, disinfection is the method of choice. The most effective means of disinfecting impressions is to immerse them in disinfectant solution for 30 minutes. Most hydrophobic impression materials exhibit minimal distortion when disinfected in this manner. Irreversible hydrocolloid (alginate) and hydrophilic silicones distort when immersed and can be disinfected by spraying and placing in a sealed plastic bag for manufacturers recommended time. Internal disinfection (replacing water with disinfectant before impression taking) is the method of choice for alginate, since it allows immediate pouring of the impression after removal from the oral cavity.
The individual methods of disinfection peracetic acid (PAA) and UV radiation and combined process PAA/UV in water (synthetic) and sanitary wastewater were employed to verify the individual and combined action of these advanced oxidative processes on the effectiveness of inactivation of microorganisms indicators of fecal contamination |i|E. coli|/i|, total coliforms (in the case of sanitary wastewater), and coliphages (such as virus indicators). Under the experimental conditions investigated, doses of 2, 3, and 4 mg/L of PAA and contact time of 10 minutes and 60 and 90 s exposure to UV radiation, the results indicated that the combined method PAA/UV provided superior efficacy when compared to individual methods of disinfection.

Heads of both basic and senior high schools (SHSs) in the Ashanti Region have called on the government to consider factoring into the programmes of both the Ministry of Education (MoE) and the Ghana Education Service (GES) a quarterly disinfection exercise in schools.. This, according to them, would not only fight the coronavirus disease (COVID-19) but also protect the students from contracting it.. The heads of schools made the call on Thursday, 25 September, 2020 during the third phase of the nationwide disinfection and fumigation exercise in basic and SHSs in the Ashanti Region.. Speaking to journalists, the Headmaster of Kumasi Academy, Mr Samuel Kwame Gato, entreated the MoE and GES to consider the matter of quarterly disinfection in schools seriously, particularly as the virus was still lurking.. He said the first and second exercises helped his school a great deal, thus insisting that the third one would do same as they welcome the second year students back to school.. He was optimistic ...

By Chris Adam. The COVID-19 pandemic has shed new light on the needs for improved disinfection methods, both for individuals and facilities.. Purdue University innovators have developed an airborne disinfection method - using food-coloring dyes - to be applied to the entire body and rooms for sterilization purposes and lowering the risk of infection.. The Purdue teams disinfection method uses edible materials. The Purdue team presented the technology in July during a COVID-19 virtual conference sponsored by the National Council of Entrepreneurial Tech Transfer.. Most of the antiviral and antibacterial sprays used for airborne antiviral and antibacterial disinfectants, such as aerosolized hydrogen peroxide, ozone, and deep ultraviolet illumination, are a biohazard risk to humans, said Young Kim, an associate professor of biomedical engineering at Purdue. Additionally, disinfectants containing titanium dioxide and noble metal nanoparticles pose carcinogenic and cytotoxicity risks.. Kim also ...
The hand disinfectant dispenser is a mobile disinfectant column that can be used wherever classic wall mounting of disinfectant dispensers provides difficult. We generally recommend a sensor disinfectant dispenser in connection with a stand column for entrance areas. Thus, the dispenser is not only more prominent, but can also easily change its location.. Many fully automatic dispensers can also be used on tables or cabinets as a stand-alone device - so they can always be used right where the possibility of hand disinfection is wanted.. The tilt-resistant design of Voitair disinfectant dispensers is easy to clean and can easily be used in changing locations.. ...
CHALLENGES AND CURRENT CHOICES: Certain pathogens present a challenge to kill effectively: parvovirus, protozoal oocysts, mycobacteria, bacterial spores and prions resist most disinfectants but can be eliminated through heat, especially steam, which will kill protozoal oocysts. Heat is the safest and most effective disinfectant, but cannot be universally applied. Temperatures in washing machines and dishwashers should be at least 60 °C to eliminate pathogenic spores and resistant viruses. Enveloped viruses are susceptible to most disinfectants; of the non-enveloped viruses, parvovirus is recognised as being the most difficult to eradicate. Sodium hypochlorite is recommended for many applications: cleaning of floors, laundry, food preparation surfaces and utensils. Skin scrubs and rubs containing alcohols are more effective than those containing chlorhexidine, and less subject to contamination ...

  • The global impacts of the coronavirus disease 2019 (COVID-19) are already starting to be felt, and will significantly affect the Skin And Wound Disinfection market in 2020. (
  • This report provides a quantitative analysis of the current trends and estimations from 2020 to 2026 of the global Skin And Wound Disinfection market to identify the prevailing market opportunities. (
  • This article originally appeared in Water & Wastes Digest January 2020 issue as "Disinfection Byproduct Filtration. (
  • UV water disinfection is highly effective in disabling up to 99.9% of harmful organisms, requires no contact with toxic chemicals, and produces no harmful byproducts. (
  • When chlorine reacts with these precursors, a variety of chemical reactions take place, including the formation of disinfection byproducts (DBPs). (
  • The researchers then went on to look at the distribution of disinfection byproducts in 11 types of indoor pools, and found that more than three-quarters of the pools had inorganic combined chlorine concentrations that exceeded National Swimming Pool Foundation guidelines. (
  • Disinfection byproducts (DBPs) are over 1,000 times more toxic than chlorine itself, for example. (
  • I've already written about the dangers of disinfection byproducts (DBPs) on several occasions over the past few years, mostly as it relates to your municipal drinking water , which is also chlorinated to destroy disease-causing bacteria. (
  • Disinfection is applied in water as well as wastewater treatment as a finishing step so as to destroy pathogens but the cause of concern regarding the disinfection process is the formation of disinfection byproducts (DBPs). (
  • With new regulations on the horizon, SCWS determined the Talladega/Shelby Water Treatment Plant (WTP) in Shelby County, Alabama, needed more effective removal of disinfection byproducts (DBPs). (
  • Human use increased significantly the disinfection byproducts concentrations and mutagenic potencies for most pools and spas. (
  • Waters produced as a byproduct of oil and gas development were found to yield high concentrations of disinfection byproducts (DBPs) when treated. (
  • Meticulously clean patient-care items with water and detergent, or with water and enzymatic cleaners before high-level disinfection or sterilization procedures. (
  • High-level disinfection kills all micro-organisms (bacteria, fungi, and viruses) except bacterial spores. (
  • What is low-level and high-level disinfection of ultrasound probes and when are they required? (
  • AIUM has stated that high-level disinfection of ultrasound probes for internal use is mandatory. (
  • The key factors driving the growth of this market include the increasing number of ultrasound imaging procedures, rising incidence of hospital-acquired infections due to the improper reprocessing of ultrasound probes, increasing adoption of high-level disinfection systems for critical and semi-critical ultrasound probes, and technological advancements in ultrasound probes. (

  • The high-level disinfection segment is estimated to register the highest CAGR during the forecast period. (
  • Disinfection by-products (DBPs) result from chemical reactions between organic and inorganic matter in water with chemical treatment agents during the water disinfection process. (
  • As regulations are tightened on established DBPs such as THMs and HAAs, drinking water treatment plants may switch to alternative disinfection methods. (
  • Filtered water is pumped through the GAC to remove the natural organic matter (NOM) from the source of water before disinfection, preventing the formation of DBPs. (
  • Swimming in chlorinated pools involves exposure to disinfection by-products (DBPs) and has been associated with impaired respiratory health. (
  • Chlorinated disinfection agents such as chlorine and chloramine are strong oxidizing agents introduced into water in order to destroy pathogenic microbes, to oxidize taste/odor-forming compounds, and to form a disinfectant residual so water can reach the consumer tap safe from microbial contamination. (
  • A few important points about disinfection should be made before choosing a disinfectant for routine farm use. (
  • The disinfection service utilizes a hypochlorous acid (HOCl)-based non-toxic, certified organic disinfectant that is EPA-approved to kill COVID-19, yet safe to use on food and beverage. (
  • the type of disinfectant used ,say for considering case of disinfection by chlorine dioxide (ClO2) substantial amount of chlorite (ClO2 -) is formed which acts as a precursor or product. (
  • BALTO uses data like this to plan its disinfection routine by itself - starting with the question of which routes are the best ones to choose through to the optimum disinfectant for the materials to be treated. (
  • Equally thorough disinfection control testing of filling and processing equipment must also be conducted to ensure that disinfectant residues do not remain and subsequently contaminate the final food and beverage products. (
  • MQuant ® Test strips are pocket-sized laboratories for quick and simple analyses of chemical disinfectant parameters to ensure the safety of your production line after disinfection. (
  • Then, using either a commercially labeled disinfectant or a mixture of 1 part bleach to 9 parts water, spray the materials until fully soaked and let sit 5 minutes, or follow the manufacturer's instructions for dilution and disinfection time. (
  • Enhanced disinfection services feature top-quality solutions from leading cleaning providers, and leverage the best-in-class processes that our market-leading sister brands ServiceMaster Clean and ServiceMaster Restore employ for disinfection services. (
