    Staphylococcus aureus is a gram positive bacteria which on microscopic examination that appears in pairs, short chain, or as bunch grapes like clusters. (CDC. S. aureus) The symptoms of this bacteria is usually sometimes rapid or acute which is due to the induvial susceptibility amount of toxin, amount of contaminated food eaten, amount of toxin that is in the food digested, and also the general wellbeing of the human. On the other hand, Methicillin – resistant Staphylococcus aureus or MRSA is

    Staphylococcus aureus Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact. Colonies of S. aureus appear in pairs, chains, or clusters. S. aureus is not an organism that is contained to one region of the world and is a universal health

    The MRSA infection, Methicillin-resistant Staphylococcus aureus, is a type of staph infection that is particularly resistant to conventional antibiotics, making it extremely difficult to treat and mitigate. Generally, this infection spreads in hospitals and other healthcare facilities, and populations at risk include those with weak immune systems, young children and the elderly, the homeless, those in prison, and anyone in crowded, busy unhygienic areas. MRSA is diagnosed through the testing of

    Gram-positive cocci are gram-positive bacteria with a spherical shape. Staphylococci are gram-positive facultative anaerobe. The most pathogenic staphylococci are staphylococcus aureus. This organism commonly causes skin infections such as Scalded Skin Syndrome and sometimes causes pneumonia, meningitis, endocarditis, toxic shock syndrome, and septicemia. Diagnosis of Staphylococcal infections is done by Gram Stain and culturing the infected area. Chest x-rays, sputum testing, and clinical evaluation

    Janice was seen in the Infectious Diseases Clinic on December 4, 2013. As you recall, she was being treated for a very complicated methicillin-sensitive Staphylococcus aureus infection which was multifocal in nature. She had several skin lesions including a carbuncle on the right lower leg, a septic right knee and a large subpectoral and subdeltoid collection on the left. Despite a history of penicillin allergy she was given a staged challenge with cloxacillin and tolerated this well. She has been

    From Staphylococcus aureus to MRSA Abstract I investigated the difference between Staphylococcus aureas and its super bacteria form of Methicillin-resistant Staphylococcus aureas. I used books, websites, and scholarly projects to understand the topic at a molecular level. After researching penicillin, Staphylococcus aureas, and Methicillin-resistant Staphylococcus aureas, I found that both the drug and the bacteria use enzymes as their defense and attack mechanism. Penicillin uses a ß-lactam

    whatever treatment is used to destroy it. These microbes will then multiply themselves and eventually cause a new strain of disease that needs a new treatment method. For example, Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of bacteria that mutated from the bacteria Staphylococcus aureus. This specific strain came about by natural selection against Methicillin, as its name suggests. The strain must have already previously existed before patients were treated with Methicillin and

    Staphylococcus aureus also known as the staph infection is a group of bacteria that can cause a number of diseases as a result of infections of various tissues of the body. (Stoppler, 2014) S. aureus has long been recognized as one of the most important bacteria that cause disease in humans. It is the leading cause of skin and soft tissue infections such as abscesses (boils), furuncles, and cellulitis. Although most staph infections are not serious, S. aureus can cause serious infections such as

    Staphylococcus aureus (S. aureus) is a considered both a Gram-positive bacterium and a pathogen, and is capable of causing many human diseases (Gordon & Lowy, 2008; Deurenberg, Vink, Kalenic, Friedrich, Bruggeman & Stobberingh, 2006). S. aureus is one of the most common causes of soft-tissue and skin infections (SSTIs) (Hansra & Shinkai, 2011). It can also cause post-operative infections at the wounds site, necrotizing pneumonia, and bacteraemia (Deurenberg et al., 2006). Resistance to methicillin

    called a “superbug” due to its strong antibiotic resistance, Methicillin-resistant staphylococcus aureus (MRSA) is the most pathogenic of all staphylococci. It has been found to be responsible for a large number of infections that are difficult to treat and is a growing concern in the health care system. At any given time, approximately 20% to 30% of individuals in the community are colonized with staphylococcus aureus (S. aureus) and are persistent carriers, up to 50% are intermittent carriers

    Aseptic Technique and Culturing Microbes, I realized the large amount of microorganisms that can be found in everyday life. Many different types are found with in the human body. Theses experiments focused on two types of bacteria. First was Staphylococcus epidermidis, found on the skin, and second was Lactobacillus acidophilus, found in the gastrointestinal tract. Both have similar needs for growth when it comes to temperature, however, different growth environments are used. In order for growth

    immediately ordered and performed a catalase test to differentiate streptococcus from staphylococcus, and noted that the organism was catalase positive. From this data, I could conclude that it was a staphylococcus bacteria, therefore I didn’t need to perform any testing for a catalase negative bacteria. I then ordered and performed a coagulase test. Subsequently, I was able to conclude the organism was staphylococcus aureus.

    After the end of the experiment the unknown 10 sample was Staphylococcus epidermidis. Came to this conclusion by first beginning with a Gram Stain test. By doing this test it would be easier to determine which route to take on the man made flow chart. Gram positive and gram negative bacteria have a set of different tests to help determine the unknown bacterium. Based on the different tests that were conducted in lab during the semester it was determined that the blood agar, MSA, and catalase test
