Essays on Disinfection

Healthcare environments are significantly prone to the risk of infection. Apparently, given the many avenues for possible infection that are evident in healthcare environments, there is an urgent need for intervention that such places demand. Several studies have revealed that all the people who participate in such environments stand a risk of getting infected, an aspect that further raises concern on the way those in charge of such places conduct their activities. The current paper identifies where the risk stems from, the possible interventions that should be initiated to curb the involved risks and it provided a reliable model ...

Felician University Avsar, Kasikci, and Yagci’s article titled Hand Washing of Nursing Students: An Observational Study applies the qualitative approach to help illuminate how hand washing is intricately related to the transmission of hospital infections (Avsar et al., 2015). Ideally, this article proceeds from the assertion that hand washing is a major contributing factor to hospital infections. Accordingly, the researchers seek to investigate and determine the behaviors of students with regards to hygienic hand washing. The intention of this paper is to compare this qualitative article with a quantitative article exploring the same topic; handwashing. The quantitative article ...

Ultraviolet light (UV light) is a type of electromagnetic radiation that is located between visible light and X-rays in the electromagnetic spectrum. It is invisible to the human eye, and has a frequency greater than that of visible light but lesser than X-rays. It has a wavelength ranging from about 10 nm to 400 nm (ISO, 2007). UV light is a part of the radiation that comes from the sun. It can also be produced artificially by electric arcs, black lights, tanning lamps and mercury vapor lamps. The name Ultraviolet literally translates to “beyond violet”, as it has a ...

Chlorine is the most common and effective disinfectant at the moment is. Among the chlorine-free water purification methods, ultraviolet radiation, the copper and silver ions, ozonation, the use of preparations of the active oxygen of the organic polymer are widespread. In some cases a combination of above mentioned methods is the most effective. Nowadays, new technologies allow to use following methods for water perification. UV-radiation of a certain wavelength and intensity, when exposed for some time to microorganisms, damages their DNA, making them incapable of reproduction. This principle is based on UV disinfection, it kills even those bacteria which ...

Abstract

Handwashing is an important process in controlling microorganism transmission and infectious diseases. The purpose of this experiment was to determine the effectiveness of different antibacterial hand cleaners (soap, alcohol hand sanitizer and ethanol soaked wipes) on killing bacteria. Hands were sampled without cleaning with antibacterial hand cleaner (control), and after cleaning with antibacterial soap, alcohol sanitizer, and ethanol soaked wipes. Samples were taken with a sterile cotton swab and inoculated on agar plates. Each experiment was done three times. Colonies were counted, mean values and standard deviation were calculated, and data was reported. Alcohol and sanitizer and ethanol soaked ...

Section 1: Background Context and rationale for research priorities Lens handling intensifies the incidence of lens contamination. When lens are aseptically removed from the eye, they still have a high probability of harboring microorganisms. During storage, the frequency of positive microbial bioburden remains high than 50%. The presence or movement of microorganisms from the lens to the ocular surface is a route factor for contact lenses related microbial keratitis and inflammation. There is need to priotise research in this area because the results of the studies help people to understand the factors concomitant to infectious and inflammatory complications. When ...

Chlorine is used in water treatment to reduce or eradicate microorganisms, for instance, bacteria or viruses found in water (EPA, 2011). The use of chlorine for the treatment of drinking water has significantly reduced the risks or exposures to water-borne infections or diseases. Besides, the supplies of safe or treated drinking water are paramount for the health as well as the general well-being of the public. Untreated water sources, for example, streams, boreholes, dams, wells, or rain water can harbor certain harmful or dangerous microorganisms, which when consumed may cause serious infections such as cholera, dysentery, or typhoid, as ...

Abstract

In the experiment, the main objective was to compare the efficiency of two treatments in terms of Ajax and Hand sanitizer. The class was divided in two groups and Group A performed hand washing with Ajax while Group B used the hand sanitizer as hand washing agent. Cultures of the dominant hand by imprint method using Petri dish agar were done on each subject before and after the application of hand washing agents. The inoculated agar Petri dishes were incubated for a week at 37°C. Colony counts of the organisms identified were made. The mean change in the number ...
