Diagnosis of an Infected Patient
Infection is the invasion and growth of microorganisms such as bacteria, viruses, and parasites that are not normally present within the body. A prokaryotic cell is a simple cell that does not have a nucleus. One of the most common types of prokaryotic cells is a bacterium. Bacteria are differentiated by many factors including shape, chemical composition, nutritional requirements, biochemical activities, and sources of energy (Tortora 76). A patient with an infection in the upper respiratory system will need to have a sputum sample sent to the lab for further evaluation to determine the cause in order to accurately treat the infection. While many microorganisms can be the cause of infection,

Spores can be stained using specific dyes, such as malachite green, that are absorbed by spores in the presence of heat (Noonan).
Escherichia is a genus of aerobic gram-negative rod-shaped bacteria of the family Enterobacteriaceae that form acid and gas on many carbohydrates, such as dextrose and lactose, but not acetone, which include occasional pathogenic forms, including some strains of E. coli which are normally present in the human intestine as well as other forms which typically occur in soil and water (Webster). Escherichia coli is a gram-negative bacilli that rarely varies in shape and size and when stained often resemble safety pins because the ends of some bacilli stain more densely than does the middle; which is a characteristic called bipolar staining which is common in enteric gram-negative bacilli (ASM). Gram negative cells have a thin cell wall layer and will stain red to pink. The staining process is the same as Gram positive, requiring four steps: applying a primary stain, adding a mordant, then rapid decolorization and completing with a counter stain. Applying the alcohol for decolorization dissolves the outer membrane and leaves small holes in the thin peptidoglycan layer through which the crystal violet-iodine diffuse. The gram-negative bacteria is colorless after the decolorization; therefore adding safranin
Poor hand hygiene - spread of germs from one patient to another or spread for hands to surfaces.
However, everybody who has contact with the patient or the environment is entitled to relevant information that will enable them to reduce the risks of transmission to

The main idea of this experiment was to correctly identify the unknown bacteria, #3. Identification of unknown bacteria yields multiple benefits in many different areas in the research of microorganisms. In this experiment I performed many different test dealing with things such as the presence of enzymes, fermentation abilities and different chemical reactions. Observations made from the tests were then compared to a gram negative unknown chart in order to identify the bacteria. Based off of my results and the chart, I concluded the bacteria #3 was the bacteria Escherichia coli. E. coli is most commonly found in the intestines of warm blooded organisms. Most E. coli strands are non pathogenic however, there are strands
The orgimsms involved in Escherichia coli 0157 is an anaerobic bacterium which is shaped like a rod and is Gram-negative. Escherichia is a foodborne pathogen which causes a variety of disease in humans worldwide. Cattle are the reservoir to the diseases. Between 1% and 50% of healthy cattle carry or shed E.coli by means of their faeces. The cattle can also contract the infection after slaughter as conmtanation can occur during slaughter or while the beef is being proceed into products suitable for human consumption. In the United states the most common way of transmission of the disease is through consuming contaminated food and water. Although it is also frequently spread from person to person impartial in communities where there is a high concentration of children such as child care services and primary schools.
The body responds differently to an infection, depending on whether it is a virus or a bacterial infection. Generally, viruses are considered to be more dangerous, but aside from generalities, there are also pathophysiological differences in the ways in which both viruses and bacteria (invasive organisms) infect human beings (hosts). When a virus is the agent that is infecting the host, the goal of the virus is to invade on a cellular level and replicate itself. “Once inside, the cells of the immune system cannot ‘see’ the virus and therefore do not know that the host cell is infected. To overcome this, cells employ a system that allows them to show other cells what is inside them” (Immune, 2015). The virus then uses the cell in order to make proteins and replicate itself, further compromising the immune system. The immune
Escherichia coli (E. coli) is a Gram-negative, rod-shaped, type of anaerobic bacterium that can be found in the environment, foods and the gastrointestinal tract of humans and animals as a normal flora (Centers for Disease Control and Prevention, 2015). It was first discovered by Theodor Escherich, a German-Austrian pediatrician and university professor, in the year 1885. He was highly keen and had a sharp mindset filled with the belief that many of the ailments suffered by his pediatric patients, could be solved by studying bacteriology. While on the pursuit for a cause that involved fatal intestinal diseases in children, he found a quick-growing, rod-shaped bacterium in the feces of his patients that would later be called E. coli (Radhakrishnan, 2009).
Hospital acquired infection is also known as nosocomial infections, which can be caused by viruses, bacteria or fungal pathogen. It is an infection that a patient can acquire while they are in hospital or another health care facility for a reason other than the infection. So most of the time, when a patient get nosocomial infection, Centers for Medicare and Medicaid Services (CMS) does not cover that treatment, and it will be the hospital charge, because the infection is caused by a poor conditions at the hospital or the health care facility, or perhaps because hospital staff did not following proper procedures. One infection that a patient can develop in hospital or health care facility is kin ulcer, which is also known as skin pressure injury.
Healthcare-associated infections are infections that affect the patients when they are in the hospitals or other healthcare setting, such as a care home or hospice, or due to health care interventions or procedures.
of this policy is to reduce the risk of infection transmission both to and from
Escherichia coli, is a gram negative, rod-shaped bacterium that can be found in the digestive tracts of humans and animals, it is an important beneficial bacteria for many organisms, it inhibits the growth of pathogenic species such as Salmonella and aids in digestion. The strains are distinguished from the presence of two surface
Healthcare is an ever-evolving field. The debate over whether contact isolation precautions for patients who have either a methicillin-resistant Staphylococcus aureus (MRSA) infection or a vancomycin-resistant Enterococcus (VRE) infection is one of the most recent inquiries that healthcare facilities are currently focused on. Healthcare-associated infections (HAIs) – infections patients can get while receiving medical treatment in a healthcare facility, are a major, yet often preventable, threat to patient safety. On any given day, approximately one in 25 hospital patients has at least one healthcare-associated infection (Center for Disease Control [CDC] and Prevention, 2010, para 1-2). The category of protective isolation, was eliminated in the 1983 revision of the CDC’s Guidance for Isolation Procedures in Hospitals. This was based on evidence that simple protective isolation offered no advantage over routine care for most immunocompromised patients (Wigglesworth, 2003, para 6). However, some studies have identified a reduced risk of infection and improved outcomes associated with the routine use of barrier precautions, such as wearing gloves and gowns in high-risk populations.
As we understand that P.S has history of recurrent UTI, this is one of the risk factors for UTI in female. Recurrent infections should prompt the clinicians to repeat the urine culture and sensitivity each time patient has symptoms (Uphold & Graham, 2013) and this was ordered for her. Reinfection may be due to:
The article that I chose, talks about the steps that are currently being taken to decrease blood stream infections in the hospital setting. Pronovost states, “professional societies and provider organizations are interested in reducing bloodstream infections” (2011). He talks about how these organizations and societies are currently working to prevent these infections by creating payment incentive, regulations, and relying on the economy. The article talks about how the CDC has taken measures on accurately identifying infections through laboratory confirmation and counts the number of days that a patient is exposed to a catheter (2011). The longer that a patient is exposed to a catheter the more at risk that they can be for infection. This
