Methicillin was first developed in 1959 as an antibiotic against penicillin-resistant Staphylococcus aureus. This beta-lactam antibiotic inhibits the synthesis of bacterial cell walls and inhibits cross-linkage between the linear peptidoglycan polymer chains, essentials for the cell wall of Gram-positive bacteria. This antibiotic is a derivative and modification to the original beta-lactam antibiotic penicillin and is penicillinase-resistant, which is effective against S. aureus bacterium’s enzyme pencillinase. However practice of this antibiotic have stopped due to the existence of MRSA. Methicillin-resistant Staphylococcus aureus (MRSA), a dangerous derivative of Staphylococcus aureus bacterium infecting unsuspected victims and continue to…
Methicillin-Resistant Staphylococcus Aureus For this assignment I have been asked to choose a pathogen, describe it and explain how the chain of infection can be broken. I have chosen Meticillen Resistant Staphylococcus Aureus. As a support worker in theatres MRSA can cause significant problems for us and for patients, therefore we have to have each patient screened before we operate and we have certain standard precautions we need to follow before, during and after surgery. Staphylococcus…
issues because of the wear and tear over the years. Meanwhile, nurses are trying to prevent injuries, they have to take precautions of their health because they are more susceptible to get sick. “As cold and flu season nears, hospitals and health systems can prepare to protect their workforce, including extra measures for those who do not receive the vaccinations for personal or religious reasons” (Gooch). Nurses take precautions to avoid becoming ill but when a nurse’s immune system is shot…
Good evening ladies and gentlemen, I am honored with the presence of you all, and thank you everyone for joining us. I am Jacqueline Sienna, a temporary researcher at Cornell University. My focus is on how drug use in animal growth increases the industrialization of meat, and how the industrialization of meat, by causing more diseases among animals, increases the use of antibiotics to treat those sick animals. These two, subsequently, promotes the growth of bacteria that is able to resist the…
So how exactly does antibiotic-resistant strain get transmitted to human? According to one of the study conducted recently, there are at least three mechanisms in which antibiotic-resistant strain can get transmitted to humans (Lipsitch, Singer & Levin, 2002, p.5753). Out of the all possible transmission methods, ingestion of bacteria from contaminated meat or water or through contact with livestock is one of the most prevalent one (Lipsitch, Singer & Levin, 2002, p.5753). Every day, Americans…
It has come our attention you contracted a MRSA infection after receiving care at Mercy Hospital. The surgical team wished to send you our regards while including information to help you understand MRSA and other antibiotic-resistant organisms. First, a MRSA infection is like any other bacterial infection. Because it is caused by a microorganism that invades the body. The name MRSA, is an acronym for methicillin-resistant staphylococcus aureus. If something sounds familiar it may be because…
not exceed the upper limit. Use references as required, they do not contribute to the word count but a properly formatted reference section must also be included at the end. Q1 What species of Gram positive organisms are likely to be isolated from wound infections? Explain your reasoning. Examples of gram positive organisms are staphylococcus aureus (staph.aureus), enterococci, micrococci and methicillin resistant…
which inhibits bacterial protein synthesis by specific reversible binding to bacterial isoleucyl tRNA synthase. Mupirocin is found to be bacteriostatic at low concentrations and bactericidal at high concentrations. Bactroban cream is used to treat infection caused by Staphylococcus aureus and beta-hemolytic streptococci including Streptococcus pyogenes. The cream is used for treatment of primary and secondary skin disorders as impetigo, nasal infections, and wound healing or abrasions (up to 10…
MRSA Effect Makaylah Hoang San Jose State University Ever since Alexander Fleming’s discovery of penicillin in 1928 researchers and scientists have developed many different types of antibiotics to help fight off illness by killing bacteria. Yet with the development of antibiotics there has been a development of bacterium that have become antibiotic resistant. The danger of this one bacterium to become resistant to antibiotics raises the question of whether or not other bacterium are able to…
MRSA is a bacterial infection, caused by methicillin-resistant Staphylococcus aureus. There are two types of infection: hospital-acquired MRSA and community-acquired MRSA. MRSA, especially community-acquired MRSA, is linked to more severe illness than methicillin-susceptible Staphylococcus aureus. The National Institute of Health, America, states that hospital-acquired MRSA is spread due to the hospital environment, whereas community-acquired MRSA is due to close skin contact between people.…
