Comparing Triclosan To Bacterial Colonies

In this experiment, we wanted to investigate which surfaces in the school had the most bacteria, and we thought that the surfaces used more would have the most bacteria. For this experiment we used agar plates, cotton swabs and distilled water in order to see how much bacteria was on each surface. Cotton swabs were wet with distilled water and then the swabbed ws wied on a 2 inch space of the surface and twisted to cover the entire swab.once we swabbed the surface, we wiped the swab on the plate in a zigzag motion holding it upside down. The girls bathroom sink handle had 389 bacteria, and the boys bathroom by the football field had 0. We saw that places commonly used such as the bathroom sinks, door handles and railings contracted the most bacteria.

This experiment illustrates the importance of handwashing and proves that hand washing is worth it. Since our hands are constantly coming into contact with ourselves and others, touching surfaces, grabbing objects, being sneezed into, etc., keeping our hands clean is one of the most effective, yet simple way we can take to avoid getting sick and spreading germs to others. Many diseases and conditions are spread by not washing hands with soap and clean, running warm water. “The human skin is a host to anywhere between 10,000-10,000,000 bacteria per square centimeter and since health care providers come into contact with pathogenic bacteria by being engaged in patient care, hand washing can reduce the risk of spreading diseases (page 3).” The objective of the experiment is to test the effectiveness of hand washing and demonstrate normal flora. This report presents the procedures and materials for the experiment, the experiment's results, and an analysis of those results.

This assignment will encompass how the results of the personal hygiene and susceptibility microbiology experiments provide a framework for the basis of the NICE Clinical Guidance (CG139) on Infection and how crucial the reasons for the hand wash protocol and hygiene is in all healthcare settings.

Ajax, which was thought to have killed the most E. coli, was because of its ingredient lactic acid, which was used as a natural anti-bacterial. A potential reason why the Ajax didn’t kill as much E. coli as what was predicted might have been that the amount of Ajax solution soaked up was not actually sufficient enough to cause an effect. Therefore, the results varied. The results were different and had a large gap between them causing three varied answers. Vinegar was thought to kill not as much as Ajax but as it turned out, had a larger zone of inhibition but didn’t efficiently kill or clear as much. The vinegar tried to kill more because of the high acid levels that entered the cell membrane and killed the cell. The vinegar that was used didn’t kill as many cells because the concentration was not high enough. Again, the same as the ajax, there were 3 varied answers. This is proposed to be because of different of length of time that it spent in the solution. Salty water which was presumed to kill the least was correct.

Rayner (2003) affirms this by stating that appropriate hand washing effectively removes transient organisms, which

The purpose of this study is to evaluate the impact of hand hygiene and how it decreases the transmission of infection throughout (Bloomfield, Aiello, Cookson, O'Boyle, & Larson, 2007). Handwashing can include alcohol based hygiene items and handwashing with soap and water. This study main focus was on North American and Europe. There is plenty of supporting rationale to backup why this study was conducted. Some of the few things this study wanted to achieve are hand hygiene is key to staying healthy and reducing infection. This needs to be followed both in the workplace and around the community to abstain from infections. Handwashing can be achieved by soap and water or hand sanitizers that removes or eliminates many microorganisms on the surface of the hand (de Oliveira Dourado, da Costa Barros, Diogo de Vasconcelos, & da Silva Santos, 2017). This can impact many individuals by using this technique to keep foreign germs off of the hands. The importance of washing hands

The aim of this investigation was to find out which antiseptics were most effective at preventing the growth of bacteria.

OBJECTIVE The objective for Rabie and Curtis (2006) was to determine the influence of hand washing on the risk of respiratory infection. METHOD The method adopted by Rabie and Curtis (2006) was to study a number of primary and review articles from five diverse databases before June 2004 in differing languages, to create a systematic review. Included in the review were studies which identified the impact of an intervention to promote hand cleansing on respiratory infections. Studies regarding hospital-acquired infections, long-term care facilities and the elderly were excluded. All studies were then evaluated where a conclusive decision was reached by consensus. Interestingly, from a primary list of 410 articles, only eight interventional studies reached the eligibility criteria. RESULTS The eight eligible studies disclosed that hand washing with antiseptic soap lowered risks of respiratory infection; the risk reduction identified as being from 6% to 44% and this range figures implied that hand washing can indeed reduce the risk of respiratory infection by 16% (Rabie and Curtis 2006). CONCLUSION Rabie and Curtis (2006) concluded that the studies collected were of insufficient quality and only one of the studies related to severe disease as well as none of the studies related

4. Based on these results, what is the importance of soap and time for effective hand washing?

Visibly soiled hands (bodily fluids, etc.) should and must be washed with soap and water to substantially rid the hands of microbes. Studies found that hand sanitizers with an alcohol content of 60-95% can kill germs effectively (instead of hand washing) compared to those hand sanitizers that contain less than a 60% alcohol concentration or those without alcohol. Growth of microbes or bacteria present on the hands may be inhibited, but will not completely rid their presence. They may still stay on the hands and not completely “wash off,” like that during the process of rinsing during hand washing where water will rinse them off the hands and into the sink. Bacteria like Clostridium dificile or E. coli are familiar organisms present in the healthcare settings and may not be effectively removed by hand sanitizers (those with alcohol content) alone. They may still be found in the crevices of the hand or ridges in between the fingers and can sometimes spread to the wrist area and forearm if not properly

The difference between antibacterial soap and normal hand soap is triclosan or triclocarbon. Triclosan is an antibacterial compound in antibacterial soap and a potent synthetic chemical. The text states, “Triclosan is classified as a broad-spectrum antimicrobial agent because it is effective against a wide range of microbes; the term antimicrobial implies

Regarding the topic, you chose to analyze. In adult patients admitted to the ICU, how does daily bathing with CHG soap or CHG bath wipes, compared with traditional soap and water baths, affect the rates of hospital-acquired infections, within the hospital length of stay? Comes in my mind several questions, other than infection prevention, where some of them have already been put into consideration such as patient satisfaction between wipe and bath, where I have heard several patient complaint in my unit that wipe is not considered as a daily bath and affect the perspective of the patient on quality of care, so I see that daily bath with soap and water is better to manage that part of concern. Another irregularity that I have noticed is that

This is an Extended Experimental Investigation on a bacterial outbreak in a workplace. The key ideas and concept, is based around health and disease with the prevention of bacteria being the key purpose. The intention of the EEI is to develop a scenario which can be modified to demonstrate and test different variables, these variables include, water, soap, anti-bacterial soap and Dettol’s effect on the chosen bacterial outbreak. The chosen bacteria is, Staphylococcus Epidermidis and its effect in an aeroplane scenario. Once the experiment is conducted the results will be used to confirm the hypothesis, answer significant questions and examine various theories and principals involved in the scenario.

The independent variable for this proposed experiment is daily bathing with CHG impregnated washcloths and the dependent variable is the incidence of hospital-acquired bloodstream infections. Extraneous variables that may affect the dependent and independent variables include demographics, patient health history, healthcare personnel compliance of hand hygiene and contact precautions, incoming visitors, microorganism susceptibility to CHG, and patient’s length of stay.

Curtis et al (2001) noted that modern methods of promoting handwashing can be effective and cost-effective on a large scale. Studies suggest that soap is widely available, even in poor households in developing countries, although it is mostly used for bathing and washing clothes (Borghi et al, 2002). In rural India and Bangladesh, soap is often considered a beautifying agent or for the physical feeling of cleanliness which it gives, rather than being associated with the removal of microorganisms or health benefits (Hoque and Briend, 1991; Hoque et al, 1995).
