Staphylococcus Aureus Essay

Although hospital-acquired MRSA seems to be more prevalent than community-acquired, they both evolved from prevalent MSSA upon acquisition of SCCmec. SCCmec is staphylococcal cassette chromosome mec, which is a mobile genetic element of Staphylococcus bacterial species. Hospital MRSA only contains one of four SCCmec types (I–IV), but the introduction of community-acquired MRSA is deeply associated with the obtaining of SCCmec IV, the smallest element and one that grants only resistance to lactams

has a mannitol phenol red pH indicator. After running most of the test, I was able to conclude that my gram positive unknown is either Staphylococcus aureus or Staphylococcus epidermis. To differentiate between the two MSA agar was used because Staphylococcus aureus ferments mannitol and should have growth because it is a gram positive bacteria but Staphylococcus epidermis does not ferment mannitol but can have growth on the agar. So, using aseptic technique, I split the plate in half and inoculated

development of novel antibacterial agents. In this proposed research, we will screen venoms from three different subspecies of Agkistrodon snake for antibacterial effects on seven different bacterial strains including Escherichia coli and Staphylococcus aureus. The expected results from this proposed project are anticipated to be a prelude to future further isolation of specific venom component with antibacterial effect and examining the specific role of snake component in antibacterial mechanism

Differential Staining and Testing for Antibiotic Production Currently, antibiotic resistance is a major concern when it comes to public health and food security. The purpose of this research is to isolate bacteria from the soil capable of antibiotic production. A local soil sample was collected and diluted through a series of serial dilutions to limit bacterial growth between 30-300 colonies, so single colonies were isolated. Single colonies were isolated onto a master plates based on variations

Siyana Praskov Professor Fair Microbiology MCB4404 2017 Scientific Article Analysis of Role of Phenol-Soluble Modulins in Formation of Staphylococcus aureus Biofilms in Synovial Fluid Abstract and Introduction Recently, Stapylococcus aureus joint infection pathogenesis has become a major burden for patients and healthcare providers. A unique biofilm formation process allows bacteria to resist standard treatments used for infections. Specifically, a serious medical issue confronted by orthopedic

Food poisoning is caused by many fungi and bacteria. One of the most common foodborne illnesses, Staphylococcal food poisoning (intoxification) is caused by the bacterial toxin produced by Staphylococcus aureus, which is commonly associated with the skin and upper respiratory tract. The bacteria can grow aerobically and anaerobically in many common foods such as milk, fish and custards and produces Staphylococcal enterotoxin if the food is stored at a warm temperature for a long period of time. The

is the process of breaking up or getting rid of bacteria that has been formed. It is an evidence-based intervention that can be used prevent hospital acquired infections. For example, when Staphylococcus aureus colonizes, mupirocin nasal ointment significantly reduces colonization of the Staphylococcus aureus bacteria when used correctly. It is known to be a safe, effective and economical method of

The Cultivation of Microbiological Media’s Chantelle Borrelli 20572656 Lab Partner: Poonam Furmah Matt and Katie Section #12 BIOL 240L Lab Period duration: Tuesday, October 6th, 2015 to Tuesday, October 20th, 2015 2:30 p.m. to 5:30 p.m. Introduction The purpose of the lab was to use selective, differential and enriched microbiological media’s to distinguish the growth characteristics of microorganisms. A selective media was used in a mixed culture to inhibit the growth of certain microbes

Qualitative Literature Analysis The increasing problem of Methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection greatly affects patients’ health and safety and increases unnecessary healthcare expenditures (Lindberg, Carlsson, Hogman, & Skytt, 2009). Many qualitative studies have been conducted which aimed at obtaining more understanding of patients’ experiences of being infected and isolated due to MRSA colonization. In this paper, the author aims to a) discuss her two chosen

Staphylococcus aureus is an opportunistic pathogen found mainly on skin, nose and respiratory tract 1 The gram positive facultative anaerobe is round. Transmission occurs through humans or animals, exposure to contaminated surfaces or enterotoxins presence in food 2 . Most susceptible are newborns, young children and the elderly due to reduced immune function 3, 4. Immunocompromised individuals diagnosed ( ie. AIDS, HIV, Crohn’s etc.) assume greater risk of infection 3, 5 . S. aureus causes many
