This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Staphylococcus aureus is an opportunistic pathogen and is frequently associated with the antimicrobial resistance. There has been horizontal gene transfer of Staphylococcus chromosome cassette mec (SCCmec) among the staphylococcal species that colonize a similar colonization niche, which eventually results in emergence of new variant with enhanced survival ability in terms of antimicrobial resistance and virulence level in S. aureus. Evolution and dissemination of SCCmec structure resulted in the emergence of methicillin-resistant S. aureus (MRSA) clones around the world covering hospital, community, and livestock settings. MRSA also has the ability to resist different antibiotic profiles known as multidrug-resistant S. aureus (MDR S. aureus).

Download or read book Insights Into Drug Resistance in Staphylococcus aureus written by and published by BoD – Books on Demand. This book was released on 2021-12-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Staphylococcus aureus is a coccus, gram-positive, non-spore forming, and non-motile bacterium. Its commensal and opportunistic capabilities make it able to colonize different sites of animals and humans. Resistance to antibiotics has resulted in development of new strains and new types within strains. Types of methicillin-resistant S. aureus (MRSA) include hospital-acquired MRSA (HA-MRSA), community-acquired MRSA (CA-MRSA), and livestock-acquired MRSA (LA-MRSA). There are also new strains like vancomycin-resistant S. aureus (VRSA) and vancomycin-intermediate S. aureus (VISA). Expansion in resistance is expected to give rise to newer strains resistant to antibiotics such as macrolide (erm gene), tetracycline (tet genes), mupirocin (mupR), and fusidic acid (fusD). Alternative approaches like nanoparticles, bacteriophages, phytochemicals, and more are required to tackle this pathogen. This book contains information on epidemiology, resistance mechanisms, and alternative ways to curtail S. aureus infection, as well as future research opportunities.
Download or read book Frontiers in Staphylococcus aureus written by Shymaa Enany and published by BoD – Books on Demand. This book was released on 2017-03-08 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Staphylococcus was first recognized as a human pathogen in 1880 and was named for its grape cluster-like appearance. In 1884, Staphylococcus aureus was identified and named for its vibrant golden color, which was later found to be the result of golden toxin production. Here, experts examine in-depth patterns of S. aureus colonization and exposures in humans, mammals, and birds that have led to the development of various clinical diseases. The mode of transmission of S. aureus and different methods for its detection in different samples are defined. Conventional antibiotic options to treat this aggressive, multifaceted, and readily adaptable pathogen are becoming limited. Alternative, novel chemotherapeutics to target S. aureus are discussed in the pages within, including herbal medicines, bee products, and modes of delivery.

Available in PDF, EPUB and Kindle. Book excerpt: Antibiotics represent one of the most successful forms of therapy in medicine. But the efficiency of antibiotics is compromised by the growing number of antibiotic-resistant pathogens. Antibiotic resistance, which is implicated in elevated morbidity and mortality rates as well as in the increased treatment costs, is considered to be one of the major global public health threats (www.who.int/drugresistance/en/) and the magnitude of the problem recently prompted a number of international and national bodies to take actions to protect the public (http://ec.europa.eu/dgs/health_consumer/docs/road-map-amr_en.pdf: http://www.who.int/drugresistance/amr_global_action_plan/en/; http://www.whitehouse.gov/sites/default/files/docs/carb_national_strategy.pdf). Understanding the mechanisms by which bacteria successfully defend themselves against the antibiotic assault represent the main theme of this eBook published as a Research Topic in Frontiers in Microbiology, section of Antimicrobials, Resistance, and Chemotherapy. The articles in the eBook update the reader on various aspects and mechanisms of antibiotic resistance. A better understanding of these mechanisms should facilitate the development of means to potentiate the efficacy and increase the lifespan of antibiotics while minimizing the emergence of antibiotic resistance among pathogens.

Download or read book Staphylococcus Aureus and Coagulase Negative Staphylococci written by Maria de Lourdes Ribeiro de Souza da Cunha and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers updated topics on the genus Staphylococcus, including the latest discoveries. In each chapter, the author discusses the results obtained and published during her 20-plus years as a researcher in this area. The book is divided into eight chapters, with a presentation of the genus Staphylococcus, current classification, general characteristics of these bacteria and the clinical significance of coagulase-negative staphylococci (CoNS), which are often classified as mere blood culture contaminants, but are the etiological agents most commonly associated with neonatal infections and peritonitis in patients undergoing peritoneal dialysis. Coagulase-negative staphylococci can colonize the surface of catheters and produce an extracellular polysaccharide that leads to the formation of biofilms which potentiate their pathogenicity. The book also focuses on the identification of CoNS, virulence factors responsible for the symptoms and severity of infections caused by Staphylococcus spp. These factors include membrane-active toxins, called cytotoxins, and a group of pyrogenic toxin superantigens. Several current aspects related to the virulence of S. aureus and CoNS are discussed, including isolates of different origins, phenotypic and genotypic techniques for the detection of these toxins, and the gene regulation mechanism involved in the expression of these toxins. Another extremely important topic which is discussed is the resistance of these microorganisms to antimicrobial agents. MRSA currently represent a serious threat to public health worldwide due to the rapid dissemination and diversification of pandemic clones. The epidemiology of MRSA infections is discussed highlights the importance of understanding why specific clones predominated in different regions in order to develop more effective control strategies and to choose more appropriate antimicrobial therapy. In this book, the topics are explained in a clear and objective manner and should be useful for postgraduate students, physicians and researchers.
