1.) Methicillin Resistant Staphylococcus Aureus (MRSA) is a gram-positive bacterium that is resistant to beta-lactam antibiotics such as Penicillin and Methicillin. CA-MRSA or Community Acquired Methicillin Resistant Staphylococcus is found in the community and not associated with hospitals. This strain can potentially cause disease in healthy individuals by its infamous toxin, Panton-Valentine Leukocidin which causes necrosis of alveoli. CA-MRSA is commonly found among military recruits, athletic teams, correctional facilities, nurseries, and among men who have sex with men. HA-MRSA or Hospital Acquired Methicillin Resistant Staphylococcus Aureus is primarily found in healthcare facilities and affects most people with weakened immune systems, …show more content…

Aureus is by analyzing the damaged tissue. Skin infections associated with S. Aureus usually result in Furuncles and Carbuncles, which are boils/lesions filled with abscess. Another skin infection caused by S. Aureus is Staphylococcal scalded skin syndrome (SSSS) which peels the skin’s stratum granulosum layer off causing desquamation. This is due to the toxins ability to hydrolyze desmoglein 1 which holds the keratinocytes together and the absence of desmoglein 3 in granulosum layer. The effects are red bright skin. In lab, we learned to distinguish two types of bacteria using the gram stain, gram positive and gram negative. Since S. Aureus has a thick peptidoglycan cell wall with teichoic acid, it stains gram positive. Further tests will indicate the bacteria, including the presence of catalase, sheep blood hemolysis, mannitol fermentation, halotolerance, and coagulase, which S. Aureus is positive for all. 3.) MRSA is resistant to beta-lactam antibiotics (penicillin, methicillin, etc.) and can be more virulent and invasive than Staphylococcus Aureus. MRSA carries the mecA gene, which allows the bacterium to fully construct a cell wall by coding for the penicillin binding

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.

Antibiotic resistance occurs when bacteria reformat themselves in order to become unaffected by the drugs or substances created to terminate them (About Antimicrobial Resistance). They gain resistance to the drugs which causes the drugs to be ineffective of use and leads to more harm. Antibiotic resistance commonly occurs within patients because of physicians misusing or overusing antibiotics. This creates a common resistance to patients and resulting in the constant creation for new antibiotics that would treat the bacteria (Antibiotic Resistance). The main conflict generally evolves from medical stewardship where physicians have the responsibility to optimally heal their patients to their best efforts (Medical Ethics and the Stewardship

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.

The body begins to go into toxic shock from the toxin the bacteria is giving off. Diagnosis depends on how rapidly the skin changes, redness, pain greater than the actual injury, erythema, skin necrosis, bullae and crepitus. Amputation of legs, hands, finger, toes are likely to happen to save the person 's life. Amputation occurs because the immune system can 't fight the bacteria at the

"During a time that I should have been planning for my son's college graduation and helping him prepare for his future, I was burying my only son, who only days before had been the picture of health” (IDSA Communications Staff). Theresa Drew, mother of Ricky Lannetti, tells the story of her son’s fatal experience. Ricky Lannetti was a strong and athletic twenty-one year old. Ricky had contracted Methicillin-resistant Staphylococcus aureus (MRSA), or better known as the “superbug”. He had reported having common flu-like symptoms leading up to the climax of this infection.

Clostridium difficile infection and transmission prevention continues to represent а difficult and serious challenge in patient safety and infection prevention. A single inpatient Clostridium difficile infection costs more than $35,000 in average and the estimated yearly cost burden for the health care system is more than $3 billion (MedPage Today, 2012). The epidemiology of Clostridium difficile infection is continue to change, and its presence in the community and the healthcare settings has caused healthcare personnel continue to re-evaluate approaches and perspectives. There are many risk factors for Clostridium difficile infection such as an exposure to antibiotics, advanced age, and hospitalization.

Madison Community Hospital (MCH) has collected data that has demonstrated that the there is a need to improve hand hygiene to prevent the spread of MRSA in their institution. Based on the findings it has become evident that the use of the FOCUS-PDCA model would help promote the changes necessary to prevent the spread of MRSA and by so doing minimize the risk of negative publicity that may come from such an outbreak at MCH. Through the use of data collection it was determined that roughly 40% of healthcare workers at MCH perform proper hand hygiene when entering and leaving a patient room. The FOCUS model will help define the issue, organize a plan, clarify the results to develop an appropriate processes map, understand the data to be able

Scientific Proof That Honey Is the Best Antibiotic Even scientists agree that honey is better than antibiotics, due to its natural antibacterial, antifungal and antiviral properties. The protein called defensin-1 in it can kill germs. Topically, honey can be used to destroy flesh-eating bacteria, MRSA and other pathogen bacteria.

They could be either gram positive or gram negative bacteria. Gram positive include Staphylococcus aureus, Coagulase negative staphylococci and Enterococcus spp, whereas Gram negative include Pseudomonas aeruginosa, Acinetobacter spp, Escherichia coli, Klebsiella pneumoniae, Enterobacter spp, Proteus spp, Citrobacter sp.13,14(Agnihotri N 2004,Atoyebi OA 1992).. However the pathogens which cause infections in burns patients vary from place to place, time to time based upon the duration of hospital stay.15(Ulku A 2004) various studies have clearly mentioned that gram positive organisms predominate during 1st week with replacement by gram negative bacteria in the course of hospital stay.15(Ulku A

864 Staphylococcus Aureus samples were collected from patients of Jinnah Hospital, Lahore. A cross sectional study and non probability purposive sampling was done between June 2007 and November 2008. 27.7% of isolates were found to be MRSA and was much lower than findings in other hospitals of Punjab. Maximum isolates (57.69%) were from endotracheal secretions and CV Catheters mainly in ICUs

In 1928, Alexander Fleming was working with Staphylococcus, during his research one of his plate cultures became contaminated with mold. Fleming described the results in a 1929 publication, “the contaminating mold in the staphylococcus became transparent and were obviously undergoing lysis.” (Fleming) He further explains that the organism is a P. Rubrum penicillium, which he has never found in nature. After Penicillin was approved for being an active antibiotic, it would be used for the soldiers in World War II proves to be successful life-saving

aureus) commonly colonises the skin and nose. Methicillin-resistant Staphylococcus aureus (MRSA) infection is caused by a strain of bacteria that has become resistant to the antibiotics commonly used to treat ordinary staphylococcal infections. In the right setting MRSA can cause severe and at times fatal infections such as bloodstream infection (BSI), infective endocarditis, pneumonia and skin and soft tissue infections (SSTI). In general S. aureus is sensitive to many first-line antibiotics and infections are generally treated with penicillins and cephalosporins, which act in a similar way against S. aureus. Methicillin was the first of these agents used in clinical practice and by convention the term is used when referring to resistance to these antibiotics.
