Unknown Organism Assignment Lacey Fagan Microbiology: Mrs. Rossman I was given unknown organism #14, in order to find out what organism I had, I had to perform several different biochemical tests to identify it. Starting with the Gram stain test, which is performed to differentiate Gram-positive and Gram-negative cells. After staining, when observed through the microscope Gram-positive cells are a purple color with thick peptidoglycan cell walls. Gram-negative cells are a pinkish/red color with
Klebsiella Pneumoniae Klebsiella pneumonia is a gram-negative, encapsulated, lactose-fermenting, non-motile, facultative anaerobic, urease positive, indole-negative, rod-shaped bacterium that is in the Enterobacteriaceae family (Tufts University, n.d.). Klebsiella is typically found in the nose or mouth, gastrointestinal tract (CDC, 2012). Klebsiella pneumonia was first discovered in 1882 as a pathogen that caused pneumonia (). Klebsiella can cause various types of health-related infections in the
Ventilator-Associated Pneumonia and Oral Bacteria Nelya Sirotinskiy and Danielle Davidson DHYG 221 Columbia Basin College February 9th, 2017 Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infection associated with increased morbidity and mortality. It is recognized that 36-60% of all health associated infection-related deaths are attributable to VAP (Gupta et al, 2016). Ventilator-associated pneumonia is a lung infection that develops in a person who is on a
Fungal pneumonia has many variations throughout the environment, including Coccidioides. Within Coccidioides, there are two species that are very similar. Coccidioides immitis and Coccidioides posadasii are two parasitic pathogens that affect the lung and can cause flu-like or pneumonia-like symptoms in mammalian bodies. Coccidioides is a pathogen that is part of the fungal kingdom (Taxonomy Browser). The separation of the species immitis and posadasii has been a relatively new discovery. The
Streptococcus pneumoniae, Haemophilus influenzae type b (Hib), Pneumocystis jiroveci. However, significant proportion of all pneumonia is caused by Streptococcus pneumoniae. In fact, the diseases caused by S. pneumoniae also include sinusitis, meningitis, otitis and some other problems, including septic arthritis, endocarditis and spontaneous bacterial peritonitis (WHO Pneumonia factsheet, 2013). The main aim of this paper is to familiarize the reader with Streptococcus pneumoniae and one particular
Streptococcus pneumoniae Life History Streptococcus pneumoniae is found worldwide. The common host is the human body, in which it often does not cause disease but at other times it can cause diseses in particular, pneumonia. It also causes otitis media, bacteremia, meningitis, peritonitis, and sinusitis. The route by which this organism is spread is from human to human in the form of aerosol droplets. When inside the host the organism’s primary site of pneumococcal colonization is the nasopharynx
My disease is Streptococcal pneumonia or pneumonia is caused by the pathogen Streptococcus pneumoniae. Streptococcus pneumoniae is present in human’s normal flora, which normally doesn’t cause any problems or diseases. Sometimes though when the numbers get too low it can cause diseases or upper respiratory tract problems or infections (Todar, 2008-2012). Pneumonia caused by this pathogen has four stages. The first one is where the lungs fill with fluid. The second stage causes neutrophils and red
Pneumonia is an inflammatory process of the lung parenchyma, usually infections in origin. Pneumonia causes your lungs by filing extra mucus and become inflamed. Which could decrease the lungs ability then normal lungs to take in air (Eagan pg. 506). Pneumonia is separated in three different classes and they are Community acquired Pneumonia which is also known as (CAP), Nosocomial pneumonia or Healthcare associated pneumonia and hospital acquired pneumonia, which is also known as (HCAP) and ventilator
It is imperative to be aware when elderly has been diagnosed with pneumonia, depending on severity it is essential to treat and prevent it. Pneumonia is inflammation in lung result by infection, bacteria, fungi, and virus, and described as lungs with fluid or pus causing cough with phlegm. There are two categories of pneumonia for elderly that will be discussed, community-associated pneumonia (CAP), and healthcare associated pneumonia (HAP). Why older people are susceptible and high risk to pneumonia
same species due to frequent mutation and horizontal gene transfer. Therefore, it is possible that the results obtained in our lab may vary from those provided in Bergey’s Manual. Arriving to the conclusion that the Gram negative bacteria was Klebsiella pneumoniae was much more direct. Using Bergey’s Flowchart for identification, the bacteria shared the test results and had a similar shape and
After culturing a sample of Klebsiella pneumoniae on a macconkey agar plate and seeing its bright pink colonies, I had a realization that Microbiology was the right path for me. I am fascinated by bacteria and infectious diseases; they are terrifying and slightly disgusting but also extraordinary and we can learn a lot from them. I started showing an interest in the sciences at age twelve when I had an overactive imagination and thought would someday I could create a genetically modified aqua colored
The purpose of this paper is to review and summarize an article concerning antibiotic resistance. The article chosen was “The role of healthcare strategies in controlling antibiotic resistance” by Ann-Marie Aziz (2013) published in British Journal of Nursing, Vol. 22 Issue 18. This article discusses essential components to understand how antibiotics work; different strains of bacteria; what antibiotic resistance means and consists of; antibiotic resistance when pertaining to the production of foods
The gram stain showed bacteria that was rod-shaped. Therefore, I search a picture of Klebsiella pneumoniae and it looked close to what I saw under my microscope. Furthermore, I concluded that the regular soap did not get rid of this bacterium. Slide 16.) If I were to do this experiment again, I would try using a soap bar and liquid soap. I would
Ampicillin Ampicillin disrupts the third and final stage of bacterial cell wall synthesis by binding specific penicillin-binding proteins (PBPs) that are inside the bacterial cell wall. Then facilitated by bacterial cell wall autolytic enzymes, cell lysis beings. Ampicillin is metabolized by Hydrolysis of the B-lactam ring to penicilloic acid. Microorganisms such as salmonella, Escherichia coli, campylobacter, shigella aquificae, thermotogae, chrysiogenetes, nitrospira, deferribacteres, other eubacteria
Pneumonia Journal Article Kellie Hale Mohave Community College NUR 122 Mrs. Port 9/8/2016 “In 2012, 1.1 million people were hospitalized in the US for treatment of pneumonia. The average hospital stay for these patients was 5.2 days. There were close to 50,000 deaths due to pneumonia and 95% of them were over the age of 65 (“Pneumonia”, 2016). Pneumonia is an serious condition and the pathogens that lead to pneumonia continue to spread throughout the hospitals and communities. Antibiotic
BioPatch, and alternatives like Tegaderm CHG, are an important first step in helping prevent catheter-related bloodstream infections (CBIs). As CBIs rank among the most frequent and potentially lethal nosocomial infections, the need for a device to cut down infections at the insertion site has increased. The growing numbers of infections has driven companies to consider a three-tiered approach: a maximal aseptic barrier at insertion, proper site maintenance, and hub protection. With BioPatch and
Asia, 2015). Many very common, easily treated bacterial pathogens are already known to have some level of antibiotic resistance. These include "Mycobacterium tuberculosis, Neisseria gonorrhoeae, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and species of enterobacter, salmonella, and shigella" (Nathan & Cars,
NOSOCOMIAL INFECTION A hospital-acquired infection (HAI), also called nosocomial infection in medical literature, is an infection whose growth is favored by a hospital environment. It may be acquired by a patient while visiting hospital or it may spread among hospital staff. Nosocomial infections include fungal and bacterial infections and are triggered by the decrease in resistance of a person. TYPES Modern healthcare employs many types of invasive contrivances and procedures to treat infected
poor amounts may enter through breast milk (p.131). The benefits of Tobramycin therapy can overshadow the potential danger. Tobramycin is effective at reducing growth and reproduction of gram-negative bacteria. The bacteria P. aeruginosa, Klebsiella pneumoniae, Escherichia coli, Proteus, Serratia, Acinetobacter, Staphylococcus aureus are susceptible to Tobramycin. When treating enterococcal infections, which are part of the normal intestinal flora of humans, the addition of penicillin is needed.
The tests explained above and completed to aid in the determination of the unknown bacteria were completed in a specific order which was supported with rationale and logic. A T – streak method was completed in succession to obtain a pure isolated colony. The T – streaks were completed with nutrient agar to give the organism nutrients and allow the organism to grow. Once a pure isolated colony was obtained, a Gram stain was completed which gave the Gram reaction and morphology of the bacteria. The
