VanA-type vancomycin-resistant Staphylococcus aureus.
Since 2002, nine methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) strains that are also resistant to vancomycin (VRSA) have been reported in the United States, including seven clinical isolates from Michigan. The strains harbor a plasmid-borne Tn1546 element following conjugation from a glycopeptide-resistant Enterococcus strain. In the second step, Tn1546 transposed to a residen...
متن کاملRevised manuscript AAC00346-09 VanA-type vancomycin-resistant Staphylococcus aureus
2 Staphylococcus aureus is one of the most common causes of hospital-and community-acquired infections and treatment of staphylococcal infections is complicated by the ability of this bacterial species to become resistant to antibiotics. Vancomycin is the drug of choice for therapy of infections due to methicillin-resistant S. aureus (MRSA) but increase in vancomycin use has led to the emergenc...
متن کاملFitness cost of VanA-type vancomycin resistance in methicillin-resistant Staphylococcus aureus.
We have quantified the biological cost of VanA-type glycopeptide resistance due to the acquisition of the resistance operon by methicillin-resistant Staphylococcus aureus (MRSA) from Enterococcus sp. Exponential growths of recipient strain HIP11713, its transconjugant VRSA-1, VRSA-5, and VRSA-6 were compared in the absence or, except for HIP11713, in the presence of vancomycin. Induction of res...
متن کاملMethicillin-Resistant Staphylococcus aureus (MRSA), Vancomycin-Resistant Staphylococcus aureus (VRSA), and Vancomycin-Resistant Enterococci (VRE) contamination of food samples in Iran: A systematic review and meta-analysis
During the last years, antimicrobial resistance has become one of the greatest challenges in clinical settings. Staphylococcus aureus and Enterococcus are important nosocomial pathogens worldwide. In different corners of the world, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) have been isolated from various sources including different foods of an...
متن کاملIdentification and Characterization of a High Vancomycin-Resistant Staphylococcus aureus Harboring VanA Gene Cluster Isolated from Diabetic Foot Ulcer
Objective(s) Staphylococcus aureus is a common cause of human infection, and emergence of vancomycin-resistance S. aureus is a great concern for treatment of methicillin-resistant S. aureus,(MRSA) in recent years (MRSA). Here, we report the isolation of high-level VRSA. Materials and Methods S. aureus was isolated from foot ulcer of a diabetic woman in Tehran, Iran. Antibiotic susceptibilit...
