treatments. Most notably, Methicillin-resistant Staphylococcus aureus (MRSA) strains have acquired the mecA gene, encoding the penicillin binding protein (PBP2a), which confers resistance to oxacillin and all β-lactam antibiotics 2. These characteristics, combined with other virulence factors, have made MRSA infections difficult to treat, and lead to MRSA being recognized as a significant cause of morbidity and mortality 3. MRSA is also the leading cause of nosocomial infections4–6, contributing significantly
unaffected by, commonly used antibiotics such as methicillin, amoxicillin, penicillin, oxacillin, and many others, and is consequently much more challenging to treat than most strains of staphylococcus aureus—or staph. Some antibiotics still work, but MRSA is constantly adapting, and researchers and developers are having a difficult time keeping up. Staph are common bacteria that are denizens of the human body. It is perfectly fine to carry staph; a lot of healthy people hold it within their bodies
tissue in the body.3 Infection may lead to serious life threatening diseases such as pneumonia.4 Over time strains of S. aureus were able to develop resistance to antibiotics, resulting in strains known as methicillin resistant Staphylococcus aureus (MRSA). 1.1 A brief history Before the discovery of penicillin, infection with S. aureus had a fatality rate of approximately 70%. After penicillins discovery and development, treatment of S. aureus infections became routine resulting in the death rate
methicillin-resistant S. aureus (MRSA), which displays strong virulent factors and exemplifies the need for novel medications to treat bacterial infections. Current research has examined several options for potential drug treatments as well as vaccine development. Advances in genetic sequencing techniques may help to characterize S. aureus strains to better understand outbreaks and transmission of the bacteria. The impact of S. aureus on human health inspires future research on treatments, especially for
MRSA: An evolving “super-bug” epidemic MRSA stands for Methicillin-resistant Staphylococcus aureus (MRSA) and is a bacterial infection that is highly resistant to some antibiotics. In short, antibiotics have been used since the 40's to stop the growth of bacteria. However, the more antibiotics are used, the quicker the bacteria become resistant to it while each year more types of bacteria adapt and become resistant to antibiotics. With MRSA being so resistant to many of the antibiotics, classifying
10 years alone, there have been more than 30 outbreaks of hepatitis B and hepatitis C in non-hospital health care settings like outpatient clinics, dialysis centers, and long-term care facilities. Types of HAIs The epidemiology of HAIs, or the study of HAI origins and how they are spread, is helping
of antibiotics, development of resistance to these antibiotics and bacteriophage’s potential as a treatment model has forced the scientists to turn from antibiotic research to bacteriophages research. The use of bacteriophages in treating bacterial infections in humans as well as other species is termed as phage therapy. The research on bacteriophages in the Tbilisi, Georgia started in the early 1920s. The George Eliava Institute of Bacteriophages, Microbiology and
But before those studies could be carried out, and before widespread use of maggot therapy was imaginable, several technical challenges first had to be overcome. History of Maggot Therapy Early Observations For centuries, the beneficial effects of maggot-infested wounds
Abstract Dairy food staff such as soft cheese,cream cheese,raw milk,sour cream,yoghurt and probiotic yoghurt products can be a rich source of diverse lactic acid bacteria.The objective of this lab practical was to isolate lactic acid bacteria(LAB) form raw milk,establishment of pure cultures of LAB,identify LAB and phage recovery and enumeration of recoverd phage.Raw milk was chosen as a sample so as to have a more positive result.To identify bacteria Lab isolated from raw milk,biochemical,morphological
frequencies in the ICU structure from the nurse's perspective and conclude by highlighting the significance of using high service quality measures in the ICU. Overview of the literature With regards to reducing nosocomial infections rates, in a recent study on the C-difficile infection impacting the state of patients in ICU, Muto and colleagues (2007) also concentrated on a number of sanitizing practices that could prove to be helpful in reducing nosocomial infection rates in ICU settings. They supported
