Staphylococcus aureus

potassium Tellurite being reduced. From the results it can also be said that this particular strain is coagulase-positive as hemolysis was present. Boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome are some of the effects of Staphylococcus aureus. Salmonella Shigella Agar is used for the isolation of Salmonella spp. and some strains of Shigella spp (neogen). Beef extract, enzymatic digest of casein and animal tissue provide suitable sources of nitrogen, carbon and vitamin…

by Streptococcus pneumoniae or Staphylococcus aureus (Rynda-Apple, Robinson, & Alcorn, 2015). Many efforts to resolve this pathology have focused on the immunomoldulatory effects incurred during the primary influenza infection while little attention has been directed toward whether bacterial physiology and gene regulation change during influenza infection. Approximately 30% of the population in developed countries are persistent asymptomatic carriers of S. aureus within the nares and an…

Regular MRSA can be caught by Meaning it is very common in athletes who play sports like American football or Rugby. And following simple habits such as washing your hands frequently can ultimately reduce Methicillin-Resistant Staphylococcus Aureus by 40%. The name Staphylococcus Aureus comes from the time when this disease could be cured by the antibiotic Methicillin. But as time went on the disease kept on transforming…

Table 2. Results for the antimicrobial susceptibility tests using the BSAC method Organism Microbial Resistance (mm) CFX CXM CTX CPM Control 310217 704476/2 706498 310258 CFX = Cefalexin. CXM = Cefuroxime. CTX = Cefotaxime. CPM = Cefepime. R = Resistant. S = Sensitive. Table 2 highlights resistance/sensitive of the dissimilar microorganisms to the different sorts of antibiotics. Data of table 2 demonstrates that E.coli strains produced sort of difference in resistance.…

Three agar slants and three nutrient broths were inoculated with Staphylococcus epidermidis using aseptic techniques for transferring samples from broth, agar, and plate cultures. A sterile inoculating loop was used to transfer a loopful of culture from the culture to the sterile media. The lip of the culture tube and inoculated media tube was flamed before and after transfer. The inoculating loop was reserialized after transfer was complete. An agar deep transfer of S. epidermidis was also done…

When providing patients with acute care in a hospital setting it is imperative to know the type of care that is required for each patient and ensuring you have the evidence and practice in order to implement the care efficiently. As part of the Nursing Integrating Concepts this semester there has been a huge emphasis on evidence and how this backs up the type of care, we as nurses should provide to patients. In this essay I will be discussing what evidence is in the form of infection control in…

Gram staining is a technique where certain stains are used to identify bacteria. It was discovered in 1884 by Hans Christian Gram where he used stains to differentiate bacterial cells in diseased lung tissue. Gram staining has evolved over time to become a trusted and common diagnostic tool used in clinical and research settings. Gram stains are mainly used to identify unknown bacteria. It is often the first test used on an unknown sample of bacteria. For medicinal uses gram staining is commonly…

The objective of this activity was to use the knowledge that we obtained throughout the semester, with the goal to correctly identify two unknown bacteria. Organism number thirteen is Escherichia coli. On the first day, I conducted a gram stain and noticed that the bacteria were pink, meaning that the bacteria are gram negative. I also recognized that the bacteria were rod shaped therefore they were bacillus. I also noticed that the arrangement appeared to be single celled. I also put the…

MSA is the sugar mannitol. Organisms capable of using mannitol as a food source will produce acidic by products of fermentation that will lower the pH of the media. The acidity of the media will cause the pH indicator, phenol red, to turn yellow. S. aureus is capable of fermenting mannitol, but not P.…

Staphylococcus aureus is a pathogenic gram-positive cocci bacteria that grows through fermentation and anaerobic respiration. Its growth experiences three stages— a lag phase where infection initiates, an exponential stage S. aureus quickly grows, and a stationary phase where the bacteria alters cellular metabolism for long-term survival. The species is known for its golden-colored colonies, and 50 percent by mass peptidoglycan cell walls (Gordon and Lowy, 2008). S. aureus is the leading cause…
