Staphylococcus aureus

INTRODUCTION Staphylococcus aureus is a type of bacteria commonly found on the skin and hair as well as in the noses and throats of people and animals. These bacteria are present in up to 25% of healthy people and are even more common among those with skin, eye, nose, or throat infections. Staphylococcus aureus can cause food poisoning when a food handler contaminates food and then the food is not properly refrigerated. Other sources of food contamination include the equipment and surfaces on…

Title The analysis of Mini unknown microbe# 1R Summary A series of tests was done with Microbe #1R for identification. A Gram stain was done it reveal a gram positive cocci result. A streak plate was completed revealing that the microbe was round/filamentous, convex, erose, granular, yellow, and opaque. The next test was the Tryptic Soy Agar plate for color. Followed by the oxidase test and last was the Mannitol Salt Agar test. Thus microbe #1R was Sporosarcina…

Methicillin Resistant Staphylococcus Aureus (MRSA) was first discovered as the superbug in the United Kingdom in 1961 and because of its nature of resisting antibiotic treatments, it was difficult to treat this bacterium (Sanders, 2012). Staphylococcus Aureus (S. Aureus) is one of the normal floras that make ecological niches on certain body parts but usually on the anterior nares. It is a commensal organism that can also be pathogenic if its ecological niches’ such as body’s defense system…

coli), Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis)), Nutrient agar plate Experiment 1.5 commenced by dividing the Nutrient agar plate into four equal segments. Aseptic technique was used to pick up a sample of broth culture using the inoculating loop…

Introduction Staphylococcus aureus is one of the most successful human pathogens, which can be detected in varied parts of the world . ()Some factors including virulence factor and drug resistance are efficacious in increasing infectious related death rate. Firstly, Methicillin-resistant Staphylococcus aureus (MRSA) strains were recognized in the early 1960s, moreover, they considered as a nosocomial deathful pathogen due to their role in increasing costs and bedridden length() In 2010 almost…

bacteria called Staphylococcus aureus grow and release a poison into the vagina. Toxic shock syndrome is rare though it does affect an estimated 1 in 700 women. How long is too long? The recommendation to change the tampon is every 4-6 hours. This helps the…

Table 1 shows the all the isolates that produced a zone of inhibition for the ESKAPE pathogen, Staphylococcus aureus. In total, twenty six isolates were tested against Staphylococcus aureus. However, only eight showed a zone of inhibition. The size of the zones varied for each microorganism. Table 2 shows the results of the biochemical and morphological tests. The test that were performed were Sim, FTM, oxidase, catalase, MSA, blood agar, Acid fast stain and endospore stain. The sim and…

how to know whether the culture is a selective or differential media. The culture bacteria that will be using are E. coli, Bacillus subtilis, staphylococcus aureus and Proteus vulgaris. V. To learn how to find the extracellular enzyme production by bacteria. The culture bacteria that will be using are E. coli, Bacillus subtilis, and staphylococcus aureus. Result i. The two…

therapeutic targets for Staphylococcus aureus. He states that metals are required for infection and that bacteria encode high affinity metal acquisition systems. Heme, which is a cofactor of hemoglobin, is known to be the most abundant iron source in the vertebrate host, and is the main focus of this seminar. The first step in heme metabolism in Gram-positive pathogens occurs in an iron-regulated surface determinant (isd) system, which has a hemoglobin receptor called isdB. S. aureus…

affinity for beta-lactam, reducing access to PBPs, or developing enzymes which act against the antibiotics, known as beta-lactamases (Rice 2012). The first method,that of producing new PBPs is most common in gram-positive bacteria, such as Staphylococcus aureus, which produces PBP2a,or Enterococcus faecium, which produces PBP5 (Rice 2012). Gram-negative bacteria however favour the production of beta-lactamases (Rice 2012). These enzymes9e similar in structure to PBPs, and so are able to catalyse…
