High School Bacteria Experiment

The dirtiest thing you own maybe your cell phone. Imagine what touches your phone the most, probably your hands and face. Since cell phones are everywhere and have become one of the most helpful tools of our generation, they have their drawbacks. The use of cell phones happens everywhere today, one place being the hospital. From a study of phones and spreading of bacteria associated with health care associated infections, Karabay states, “Our study reveals that mobile phones may get contaminated by bacteria (such as Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae), which cause hospital infections, and may serve as a vehicle for the spread of nosocomial pathogens” (Karabay, 2007). Touching contaminated

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.

CDCs clean hands count campaign aim to improve healthcare provide adherence to hand hygiene recommendations, address, myths and misperceptions about hand hygiene and empower patients to play a role in their care by asking or reminding healthcare providers to clean their hands and the most germs that cause serious infections in healthcare are spread by people’s action, every patient is at risk of getting an infection while they are being treated for something else, hand hygiene is a great way to prevent infections and healthcare providers clean their hands less than half of the time they should, good hand washing is the first line of defense against the spread of many illness.

The purpose of the bacterial unknown independent study experiment completed throughout the course of this lab was to determine the identity of an unknown bacterial species. The unknown bacteria sample was chosen from numerous samples provided by the instructor. The starting unknown sample, unknown #15 was a mixed bacterial culture and a broad approach taken to identify the sample. Various biochemical tests were completed to identify the bacterial species along with the use of databases such as Gideon and Bergey’s to compare the test results of known bacteria to the results of the unknown sample. Information was gathered from the other sources and databases and phenotypic testing completed and the results compared to the database results. Aseptic

The article titled, “ ‘Harmless’ Things You Should Really Wash Your Hands After Touching” by William Harris, is that every day of people's lives they get germs from all the things they touch.

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

Some brainstorming was done to determine the lineup of the bacteria on two Petri dishes. Next, the experiment started with the labeling of the two Petri dishes. This was followed by a mistake that occurred, which was corrected with an orange dry-erase marker. Then our hands were sanitized with hand sanitizer, and was followed with bacteria collecting. The bacteria was collected, from the silver-ish, doorknob on the inside of the door near room B216 (with evacuation plan), and the beginning part of the handrail at the right found near the stairs of the B building opposite to Luck Hall. After that, the process was

After gaining some knowledge about bacteria, we were giving an investigating bacteria growth lab to do. Our objective was to observe the conditions required for bacteria to grow and to test the effectiveness of substances that may be antibacterial, disinfecting, and or sanitizing. My group and I began our procedure by gathering all the bacteria by swabbing our necks and mouths. After this, we inoculated the culture by rubbing the bacteria on the agar, a nutrient rich gel made from sea kelp, on the bottom side of the container where we grow bacteria, the Petridish. We hoped for the results to come back with little or even no colonies and an immense zone of inhibition around the tiny circle cut out of filter paper covered in toothpaste, Neosporin, and Chlorhexidine Gluconate 4% Solution.

The purpose of this experiment was to identify an unknown microbe with the knowledge we have obtained from previous experiments. We used our knowledge of staining properties, cell morphology, cell arrangement, and biochemical tests to identify the microbe. Our professor provided us with a flowchart to guide us through the elimination process of this experiment.

Hand hygiene has been an issue that needed enhancement. In the United States (US), 1in every 25 patients admitted in the hospital turn out to be infected, making it a total of 722,000 infections each year (Centers for Disease Control and Prevention (CDC), 2016). These infections can be critical and very unsusceptible to treatment. Proper hand hygiene can be used to inhibit the transmission of disease-causing agents. Healthcare workers (HCWs) should exercise proper hand hygiene to inhibit the circulation of germs to patients. Hand hygiene should be done prior to patient contact, following contact with blood, body fluids, or non-sanitized surfaces, prior to invasive procedures, following taking off gloves and patient 's contacts. In

While leading this analysis, gene expression was critical to the results of the non-transformed and changed cells. In its procedure of choice, the bacterial cells should have picked if they ought to allow the ampicillin safe quality, therefore indicating commendable components of quality expression. The Escherichia coli's cells were not changed, there seems to have been an error during the experiment. There should have been a slight change in a way that there should have been a colonial growth design in the bacterial cells that had ampicillin safe plasmid. (Hidalgo, Nuria Fernández) On the other hand the cells that were on the ampicillin (lux, control, and NP) demonstrated a colonial design because of the non-transformed cells dying due to

Bacteria are single-celled microorganisms that have been around on planet Earth for over 3.5 billion years and are found everywhere and anywhere you touch. Some bacteria can be healthy to the human body while some can “attack” and cause infectious diseases to be spread. Most bacteria located on surfaces are the cause or starting point for the majority of common illnesses. For example the flu, cold, gastrointestinal disease (diarrhea, stomach flu, salmonella infection), streptococcal infections, and meningitis. The most common place to spread germs can be in schools, offices, and other public places where multiple people have contact with objects. So, that is why it is important to decrease amounts of bacteria on surfaces to prevent the spread

General cleanliness is a very important aspect of life. Having clean hands contributes greatly to this. Our hands touch many a variety of different things throughout the school day such as water fountains, computers, book, calculators, etc. Most, if not all, of these things have all been either touched or used by other students. Take a water fountain for example. Just think of how many times that water fountain has been used. A lot, right? If you touch something that many other people have touched not only creates germ spread, but it makes your hands extremely dirty. Along with water fountains, there are many other dirty things that we touch throughout

At the University of Saint Joseph there is a 40 to 60 ratio between residents and commuters. The resident’s dorm provides communal washing machines and dryers. There are 6 washing machines in Madonna and 4 washing machines in Assumption. There are approximately 164 residents that share 6 washing machines in Madonna and 81 residents in Assumption that share 4 washing machines. (Residence Halls) Washing machines clean clothes, but what cleans the washing machines? If washing machines are not properly cleaned or not properly used can lead to different microbes to grow. (Carollo) In a study of 50 homes in Tucson and 50 homes in Tampa Bay Florida they found coliform bacteria, and E. Coli that caused diarrhea in many of the washing machines. (Rostein). From further investigation they discovered that 60% of the washing machine had coliform bacteria and 10% had E. Coli in it. (Rostein). “Researchers found that 40 percent of sterile cloths washed in non-bleach laundry contained fecal bacteria. In fact, there was enough left over to contaminate the next wash load” (Rostein) Bacteria such as Salmonella, and viruses including hepatitis A, rotavirus and adenovirus where also found in the washing machines. (Rostein) “While E. Coli was killed in the permanent press drying cycle, some salmonella survived on clothes at 131oF.”(Rostein) In this project, this group will be testing to see if the facilities and students are

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.
