Staphylococcus aureus is a major pathogen in hospitals worldwide (Hamdan-Partida et al. 2010).As S. aureus has a flexible genome, this bacterium has undergone many genetic changes, and its virulent and drug-resistant strains have spread. In recent years, methicillin-resistant S. aureus (MRSA) has been a major contributor to the development of hospital and community infections (Holden et al. 2004) Pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-intermediate Staphylococcus aureus (VISA) have been spreading worldwide [1, 2]. The conventional antibacterial agents are practically impossible to inhibit the pathogens; therefore, to develop a new type of antimicrobial material is imperative Vancomycin Resistance. With antibiotic use comes the development of resistant strains. Vancomycin is typically used for suspected or known Staphylococcus aureus (Staph) infections. It is also active against a variety of other common gram-positive bacteria, such as the streptococciand enterococci species
Introduction. The rapid emergence of MDR bacterial pathogens, including vancomycin-resistant Staphylococcus aureus and MRSA, has posed a severe threat to global public health. 1 Among these, the emerging variants of S. aureus are capable of causing various illnesses in humans and animals, ranging from mild skin infections to life-threatening bloodstream infections and pneumonia OBJECTIVES Limited data exist regarding clinical outcomes of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections in children treated with vancomycin. Treatment success in adults correlates best with an area under the curve/minimum inhibitory concentration (AUC 24 /MIC) ratio ≥400. It is unknown if this relationship is useful in children A small but clinically significant portion of Staphylococcus aureus isolates with reduced vancomycin susceptibility also demonstrated reduced susceptibility to telavancin and daptomycin. This is according to data published in the European Journal of Clinical Microbiology & Infectious Diseases.. The study characterized S aureus isolates from a large tertiary care academic medical center: 50.
Background Contact precautions for endemic methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) are a resource-intensive intervention to reduce healthcare-associated infections, potentially impeding patient throughput and limiting bed availability to isolate other contagious pathogens. We investigated the impact of the discontinuation of contact. Methicillin-resistant Staphylococcus aureus (MRSA) is a major public health concern causing serious community and health-care-associated infections annually [1,2,3].Mortality rates associated with MRSA bloodstream infections (BSI) can be as high as 57% [].For decades, vancomycin (VAN) has been the mainstay for the management of MRSA BSI despite complex dosing strategies, nephrotoxicity risk.

Purpose of Review In the last 50 years, vancomycin has been the agent of choice to treat infections due to methicillin-resistant Staphylococcus aureus (MRSA). However, vancomycin treatment failure is not uncommon, even when MRSA strains are fully susceptible to vancomycin. Treatment with vancomycin requires careful monitoring of drug levels as there is a potential for nephrotoxicity. To assess the effect of a pharmacist-driven, polymerase chain reaction (PCR)−based nasal screening protocol for methicillin-resistant Staphylococcus aureus (MRSA) on vancomycin therapy duration and on rates of adverse drug events and 30-day hospital readmission
We report a case of hospital-acquired pneumonia that to our knowledge is the first description in Egypt of the emergence of vancomycin (VA)-resistant Staphylococcus aureus due to the concomitant use of β-lactams. The combination of β-lactam antibiotics and VA in the treatment of methicillin-resistant S. aureus must be avoided to refrain from inducing VA resistance; further, if there is. Abstract. A resistant mutant with vancomycin MIC of 100 µg/ml was isolated relatively easily through step pressure in the laboratory from a Staphylococcus aureus strain with initial MIC of 1.5 µg/ml for the antibiotic. Upon addition of vancomycin (50 µg/ml) to the growth medium mass increase of the culture and peptidoglycan synthesis continued but cell division (daughter cell separation.
Introduction. Methicillin-resistant Staphylococcus aureus (MRSA) was first isolated in 1960 in England, just after methicillin had become commercially available. MRSA is a derivative of S. aureus that gained resistance to β-lactam antibiotics by acquiring the mecA gene (or mecC gene) in its chromosomal DNA. 1 It has become endemic in most hospitals and healthcare facilities in industrialized. Abstract Background Vancomycin‑resistant Staphylococcus aureus (VRSA) is a serious public health challenging concern worldwide. Objectives Therefore, the objective of present study of 62 published studies was to evaluate the prevalence of VRSA based on different years, areas, isolate source, antimicrobial susceptibility testing, and the. Vancomycin is among last-resort drugs for the elimination of serious methicillin-resistant Staphylococcus aureus (MRSA) infections. Suboptimal or prolonged exposure to vancomycin is a major cause of decreased vancomycin susceptibility being a great concern toward the eradication of related infections Patients with methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA BSI) usually receive initial treatment with vancomycin but may be switched to daptomycin for definitive therapy, especially if treatment failure is suspected. Our objective was to evaluate the effectiveness of switching from vancomycin to daptomycin compared.

Among the most aggressive, yet common, human pathogenic agents is a bacterium called Staphylococcus aureus (abbreviated as S. aureus or staph) ( Tong et al., 2015 ). A ubiquitous Gram-positive microbe, S. aureus has adapted to a wide variety of species, including the human host, where it comprises the natural flora on the surface of human skin Antibiotic resistance is the most worrisome problem in treating bacterial infections. It is very important to maintain the clinical efficacy of vancomycin because of their critical role in preventing and treating life-threatening healthcare associated infections (HAIs). Therefore, this study aimed to determine the existence of different levels of vancomycin resistance among Staphylococcus. The new guidelines describe an optimal vancomycin serum AUC 24 range between 400 and 600 in patients with serious suspected or definitive methicillin-resistant S. aureus (MRSA) infections (eg, bacteremia, infective endocarditis, osteomyelitis, meningitis, and pneumonia) 1 Using genomics to understand meticillin- and vancomycin- resistant Staphylococcus aureus infections Stefano G.
