Prevalence of Vancomycin Resistance in Methicillin-Resistant Staphylococcus Aureus

Methicillin-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...

Vancomycin heteroresistance and methicillin-resistant Staphylococcus aureus.

Heteroresistance refers to the presence, within a larger population of fully antimicrobial-susceptible microorganisms, of subpopulations with lesser susceptibility. This phenomenon has been described in a wide range of microorganisms, but much recent attention has been directed toward its expression in Staphylococcus aureus. Although it has long been known that resistance to methicillin is char...

Methicillin-Susceptible, Vancomycin-Resistant Staphylococcus aureus, Brazil.

We report characterization of a methicillin-susceptible, vancomycin-resistant bloodstream isolate of Staphylococcus aureus recovered from a patient in Brazil. Emergence of vancomycin resistance in methicillin-susceptible S. aureus would indicate that this resistance trait might be poised to disseminate more rapidly among S. aureus and represents a major public health threat.

Staphylococcus aureus: methicillin-susceptible S. aureus to methicillin-resistant S. aureus and vancomycin-resistant S. aureus.

The evolution of methicillin-resistant and vancomycin-resistant Staphylococcus aureus has demanded serious review of antimicrobial use and development of new agents and revised approaches to prevent and overcome drug resistance. Depending on local conditions and patient risk factors, empirical therapy of suspected S. aureus infection may require coverage of drug-resistant organisms with newer a...

Prevalence of clindamycin-resistant Staphylococcus aureus induced by macrolide resistance

Introduction: Since the incidence of various infections caused by Staphylococcus aureus increases, the use of effective antibiotics such as clindamycin has been growing to treat the systemic and local infections caused by such organisms. Antibiotic-resistant species are emerging and spreading in today's communities due to misuse of antibiotics and incomplete treatment, turning into a serious ch...
