Testing Various Disinfectants On Bacteria Covered Toothbrushes

Thoroughly washing your hands can be one of the best ways to prevent the spread of pathogens that cause illnesses. Our bodies have several lines of defense to fight infections. It is very important to do what we can do to avoid the pathogens from entering our system in the first place. Our hands pick up microscopic pathogens from objects that were touched by people who may not have washed their hands very well. When we forget to wash our hands or don’t wash them properly, we can spread pathogens from our hands to our internal systems by touching other parts of our body. During this lab activity, my partner and I will test the effectiveness of different hand-washing times, techniques, and

Infection control is a central concept to every practice of health care providers. Its main objective is to prevent the transmission of infectious diseases from both patients and health personnel (Martin et al., 2010). In dental clinic, infection control is a continuous concern for its professionals. They have to contact patients routinely and be exposed to their blood, saliva, dental plaque and pus that may contain infectious pathogens. It is important for the dental professionals to treat these fluids as if they are infectious and special precautions must be taken to handle them. In this essay, I will highlight the scope of infection control practices in dental clinics and the ways through which infectious microorganisms are transmitted

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.

Hospital acquired infections (HAIs) affect over 1.7 million patients each year, causing almost 100,000 deaths annually in the United States alone (Johnson, 2010). According to the World Health Organization, HAIs are the most frequent adverse event in the healthcare industry. Fortunately, most of these infections can be prevented with one single intervention, proper hand hygiene (“The Evidence,” n.d.). Four out of five pathogens that cause illness are spread by direct contact. Proper hand hygiene eliminates these pathogens and helps to prevent cross-contamination and HAIs (Linton, 2015; “Hand Hygiene,” n.d.). Reduction of cross-contamination and HAIs improves patient outcomes, increases employee wellness, and lowers health care costs. Adherence to proper hand hygiene is the single most important safety measure in the health care setting. However, for many years compliance to proper hand hygiene in the healthcare industry has been dismally low. New and inventive measures must be implemented to increase compliance to proper hand hygiene and lower the rate of hospital-acquired infections.

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.

Things that are used commonly by students and staff should be routinely disinfected to ensure the health and safety of the people using the provided materials. Bacteria is related to disease (American Association for the Advancement of Science, 1885) Previous studies on the surface of a high school telephone showed that the phones had an uncountable number of bacteria colonies (Yalowitz, 2003). We know that surfaces used by the public often become contaminated because of the bacteria on peoples hands. A study on the bacteria on peoples hands showed that 28% of people have fecal matter on their hands (Judah, 2010). A study done on the contamination on public doorknobs showed that over 86.7% were contaminated (Nworie, 2012). This experiment was to show us how much bacteria is on the surface of the things we use

Epidemiology – the science that studies when and where diseases occur and how they are transmitted. CDC, Atlanta, tracks and traces diseases. ONE World (the idea that it’s all in one place, it could happen anywhere; locally, states, large counties track the incidences and occurrences of disease)

Testing the Effects of Bacteria Growth on a Non-Treated Vs. Treated Hand Name: Laura Torres Biology 1407-P Abstract The objective of this experiment was to test the effects of bacteria using a treated hand and an unwashed hand. Two plates of agar and a hand is used to retrieve the bacteria and then placed in a temperature where they can survive. Different types of bacteria are affected by the environment that slow down or increase the growth of these prokaryotes.

Over the years one of the leading causes of hospital acquired infection has been attributed to the poor hand hygiene. Whether it is due to the fact that healthcare workers are not sanitizing their hands between patients that can lead to cross contamination between patients, between staff and patients, or even staff to staff. Since a majority of hospital associated infections such Methicillin-resistant Staphylococcus aureus (MRSA) or Vancomycin-resistant Enterococci (VRE) as are transmitted via contact and can remain on surfaces for up to thirty of more days it is very easy to transmit between patients with ineffective hand hygiene. There should be accessibility to both hand sanitizers as well as handwashing areas which would make it easy for staff, patients, and visitors to follow hand washing protocols. Studies done over the past on health care workers in reference to proper hand hygiene has shown that there is still an at least a fifty percent times in which proper hand hygiene is not performed (Ara, et al., 2016). On a daily basis a health care worker comes into contact of different microbes which are easily transmitted and according to the CDC not following the proper hand hygiene along with adequate solvent is reportedly the number one factor that contributes to HAI’s (CDC, 2015). Healthcare facilities are currently making handwashing more accessible by providing alcohol based hand sanitizers outside of patient’s rooms which are more visible to visitors and staff. Studies have shown several factors that contribute to the lack of proper hand hygiene, knowledge of the spread of infection via contact with contaminated hands, the importance of having solvents such as hand sanitizers being accessible and antibacterial soap, the understanding of the proper method involved in hand washing, understaffing is also a

The goal is this project was to use our skills previously learned in class and apply them to identifying an unknown organism. These types of skills are important in many clinical setting. If a patient came in with unrecognizable symptoms using the skills we used in class one could be able to identify the organism and give the patient targeted treatment. We performed twelve experiments to help us to do so. After conduction my experiments I was able to identify my unknown as the organism Pseudomonas aeruginosa. P. aeruginosa is a “ubiquitous environmental bacterium that is one of the top three causes of opportunistic human infections.” (***) An important part of this organism

Germs are chemicals in our bodies that can either be good or they can be bad for us. Germs are tiny organisms that can cause a disease. According to Frontier it says, “Germs are so small and sneaky that they creep into our bodies without being noticed. In fact, germs are so tiny that you need to use a microscope to see them. “ There are 4 different types of major germs: Bacteria, Viruses, Fungi, and Protozoa. Germs can be in plants, animals, and people. Germs affect everything around, that is why people should wash their hands and use hand sanitizer after they touch their faces or go to the bathroom. In the next 2 paragraphs there will facts on how germs are good and how germs are bad.

My purpose of the experiment is to test what mouthwash will kill the most oral bacteria or prevent the most oral bacteria. What I want to know from this experiment is what kind of mouthwash will prevent the most bacteria and if its wort the money. I choose this topic to see what product will help me maintain the good oral health.

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.
