Comparing Triclosan To Bacterial Colonies

The purpose of this experiment is to investigate the effects of various household products may have on bacterial growth. The bacteria that was chosen as a test subject is Micrococcus luteus, which is generally considered a harmless bacterium unless the host has a weakened immune system. Among the household products that a set of groups will test are common cleaning and disinfecting products such as rubbing alcohol, Betadine, Germ-X, Neosporin, liquid hand soap, and Lysol cleaner. In the experiment, the bacterium, Micrococcus luteus, is to be swabbed and grown in a Petri dish divided into four sections with agar in each. After that, a small circle of thin paper is soaked in the four household items. Then, a piece of parafilm

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

THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI

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.

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.

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

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

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

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

Bombs, nicotine and drugs are all dangerous substances which are quite evident yet things such as simple ingredients are not so clear in the danger they pose . They actually are the ones that very dangerous and they happen to be laying right in your everyday essentials. There is an ingredient added to your everyday consumer products to reduce antibacterial contamination yet instead is found to pose a threat to numerous things in every day life. It posses danger heavily to individuals health in numerous ways as well as the environment.

There is a serious concern today about healthcare associated infection due to limited or lack hand hygiene. The concern has brought burden to patients, which many times result into additional complication posing a threat to the patient’s wellness process. In some cases, these acquired infection(s) will lead to long hospitalization or rehabilitation stay or re-hospitalization with huge healthcare cost left for patients to pay. One main cause of these infections are as a result of healthcare worker not performing proper hand hygiene before and after care and also in between patients. The healthcare associated infection spread is by direct contact from one healthcare worker’s hands to the patients and from patients to patients. Hand hygiene can be defined as is a “preventive practice to stop the spread of disease. These practices include basic handwashing, using antisepsis to kill germs on hands, and protecting the skin” (Hand hygiene, 2016). To meet to standards of hand hygiene the agents used during this process are: plain soap and water, antimicrobial soap and water and alcohol-base hand sanitizer. With the use of these agents to prevent the spread of infection, proper handwashing technique is considered the optimum practice for clean hands. I chose “Hand

The main objective of this experiment is to investigate the effect of different types of antibiotics on bacteria Bacillus subtilis and Escherichia coli. Some of the main methods used in this experiment

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).

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.
