  Background and Aims : Oxacillin-resistant Staphylococcus aureus is a major pathogen causing serious infections and treatment of such infections is very difficult. Vancomycin is the last line of treatment for resistant S. aureus. The aim of this study was investigation of epidemiology of vancomycin and oxacillin resistant Staphylococcus aureus clinical isolates in Urmia   Materials and Methods...

Abstract Background and Objective: Vancomycin is used for treatment of methicillin-resistant S. Aureus (MRSA) infections therefore, resistance to this antibiotic is increasing. We aimed to determine the antibiotic resistance pattern and frequency of vancomycin resistant S. Areas (VRSA) strains isolated from clinical samples. Material and Methods: In this cross-sectional study, 100 S. Aureus iso...

Background and purpose: Methicillin-resistant Staphylococcus. aureus (MRSA) is specific strain of S.aureus that is a major cause of nosocomial infection. Nowadays, Vancomycin is the first-line treatment of severe MRSA infections. However, resistance to Vancomycin is reported in the form of Vancomycin-resistant Staphylococcus aureus (VRSA) too. This study aimed at determining the prevalence of M...

background vancomycin resistant isolates of enterococcous faecium (vre) have previously been reported from tehran hospitals. however, little data were available on the genetic heterogeneity of vre isolates among the iranian population. therefore the emergence of infections with the new clones of vre needs to be investigated. the drug resistance surveillance program at labbafinejad hospital has ...

conclusions there were diverse phenotypic changes among vancomycin-non-susceptible s. aureus isolates. this may be due to the variety of related regulatory systems. the diversity of phenotypic expression may result in its misidentification in routine laboratory checks. materials and methods a total of 130 methicillin-resistant s. aureus (mrsa) isolates were studied, including 49 vssa, 28 hvisa,...
