Staphylococcus Aureus belongs to the extremely common bacteria of microflora of the skin and mucous membranes of the humans. These pathogens cause many infections, including superficial and deep purulent infections, poisoning, urinary tract infection etc. In the US, staphylococcus bacteria are supposed to be the leading cause of sepsis, postoperative wound and prosthesis infections. In addition, staphylococcus belongs to one of the leading causes of bacterial food poisoning. Staphylococcus Aureus is one of the most dangerous human pathogen. It is highly virulent with the high rate of resistance to the treatment and antimicrobial infectious agents. The mentioned above proves that the Epidemiology of Staph. Auerus as foodborne pathogen requires
Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done. My bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests. This is because with staphylococcus organisms, these are the only tests
Clostridia difficule (C. diff) is a problematic microbe because its has two key virulence factors, toxin A and toxin B. Toxin A is an enterotoxin, which can cause copious water, potassium, and bicarbonate losses. On the other hand, toxin B is a cytotoxin, which can cause damage to the cells. These toxins can be both asymptomatic or cause pseudomembranous colitis in an individual. C. diff is also an anaerobe gram-positive bacterium, which means that it can thrive in environments without oxygen. This is a dangerous factor for humans and animals.
Nguyen Nguyen Professor Microbiology 1 May 18th, 2016 01MW – Staphylococcus Epidermidis The Staphylococcus Epidermidis is classified as bacteria. Scientists reckon it to Firmicutes phylum and adjust it in Bacillales order of Bacilli class. This bacteria belongs to Staphylococcaceae family.
Methicillin resistant Staphylococcus Aureus (MRSA) surveillance screening in an acute care setting can be done through the use of targeted screening of patients who only meet the predetermined criteria or through the use of universal surveillance of all patients. Although it is necessary and appropriate for patients in ICU to be screened for MRSA due to the high level of care, patients in a non-ICU acute care setting could also benefit from universal surveillance screening as they encounter similar risk of acquiring MRSA infection in the hospital setting.
INTRODUCTION: In this experiment I was testing for antimicrobial sensitivity of Staphylococcus epidermidis by using the Kirby-Bauer Diffusion test. The three antibiotics utilized in this lab were: gentamicin, novobiocin, and penicillin. I determined the effectiveness of the antibiotic by observing and measuring the zone of inhibition for each antibiotic.
Hunting nightmare bacteria Answer the following questions Case of Addy (the girl from Arizona ) 1- Based on the pediatrician observations what was Addy’s diagnosis at the Pediatric Hospital intensive care unit ? She had got infected by staff or positive bacteria called Methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a community associated bacteria that infects kids when they are playing in playing ground and getting scabs on their knee. They spread through that wound and it has very high resistance to antibiotics.
Inflammation is the main type of innate immunity our body uses against A. schmiddy. Inflammation begins by activating acute-phase proteins, and soon after vasodilation occurs, followed by redness, swelling, pain, and heat. Once vasodilation occurs, histamine and kinins are released and blood vessels permeability is increased, causing white blood cells to report to the infected area. One problem associated with inflammation is that the capsule of A. schmiddy is an important virulence factor, which helps the bacteria to resists phagocytosis. Because the phagocytes cannot destroy the bacteria cells, infection further continues and necrotic tissue forms.
In the article, “Scientists MRSA Germ in Supermarket Meats,” by Steven Reinberg. The author talks about MRSA germ and how it was found in meat at supermarkets. It explains how the germ it’s being introduced by human food handlers. It also explains how people that have cuts or sores in their skin can be more likely to get infected. Research found that humans can transfer the bacteria to meat. A study was conducted by Zhang’s team to see which meat was contaminated by MRSA.

Section 1: Identification of the unknown pathogen Patient is Terrance V. Haller, a 13-year-old male who enjoys outdoor activities such as skateboarding. No previous medical history and there are no known allergies. Terrance had a skateboarding accident where there were multiple lacerations and contusions. The wound on his forearm extending to his elbow was slow healing and therefore became pus producing. The patient has since returned to his primary care physician to find out what is going on.
Department of Health and Human Services established an objective for Healthy People 2020 to prevent HCAIs, this reflects that the U.S. health care system is committed to and serious about solving this issue. These objectives address two extremely important topics, central line-associated bloodstream infections, and methicillin-resistant Staphylococcus aureus (MRSA) infections. Also, there are other major causes of HCAIs that Health and Human Services is working on their prevention such as urinary tract infections (UTIs) associated with catheters, infections of surgical wounds and sites, C. difficile infections, and ventilator-associated Pneumonia. Researches done on HCAIs shown that we can prevent many of these infections by implementing effective strategies to eradicate it, adapting some advanced prevention tools, and following new prevention approaches. There should be a more focus on HCAIs prevention in acute care settings.
Its virulence factor comes from multiple things within the cell and these things contribute to the types of infections they cause. Two important virulence factors are a secreted protein called coagulase and clumping factor. Some other virulent factors are the capsule, enterotoxins, exfoliatin, toxic shock syndrome toxin, and alpha toxin. The enterotoxins cause food poisoning in humans. The exfoliatin caused scalded skin syndrome.
