One-point population analysis and effect of osmolarity on detection of hetero-vancomycin-resistant Staphylococcus aureus.
نویسندگان
چکیده
The original screening test and one-point population analysis (OPPA) were compared for the detection of hetero-vancomycin-resistant Staphylococcus aureus, and the influence of osmolarity on those tests was evaluated. The positivity rates and the reproducibilities were similar for both tests. The addition of NaCl increased the MIC as well as the positivity rates for both tests and the reproducibility of OPPA.

Prevalence of Vancomycin Resistance in Methicillin-Resistant Staphylococcus Aureus
Background & Aims: Staphylococcus aureus is one of the most common pathogens in nosocomial infections. Vancomycin is the most important therapeutic drug of choice for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) strains. Therefore, vancomycin-resistant Staphylococcus aureus (VRSA) or vancomycin-intermediate Staphylococcus aureus (VISA) strains are warning...
متن کاملA modified population analysis profile (PAP) method to detect hetero-resistance to vancomycin in Staphylococcus aureus in a UK hospital.
One hundred methicillin-resistant Staphylococcus aureus (MRSA) strains, isolated between 1983 and 1999, were tested alongside the vancomycin hetero-resistant S. aureus (hVRSA) strain Mu 3, and vancomycin-resistant S. aureus (VRSA) strain Mu 50, for their resistance to vancomycin. This was achieved using the screening method described by Hiramatsu, gradient plates, agar incorporation, standard E...
متن کاملA Study on the Antimicrobial Effect of Zinc Oxide Nanoparticles on Clinical Strains of Staphylococcus aureus Resistant to Vancomycin
Staphylococcus aureus, as one of the main agentsfor hospital infections,is considered as highly important because they show resistance to a wide range of antibiotics.Resistance to selective antibiotics such as vancomycin is a serious problemin the medical community; thus it seems rational to use alternative substances for treating these bacteria.The aim of this study isto investigate the preval...
متن کاملEfficacy of vancomycin-beta-lactam combinations against heterogeneously vancomycin-resistant Staphylococcus aureus (hetero-VRSA).
There have been conflicting data about the interactions between vancomycin and beta-lactam agents against Staphylococcus aureus strains with heterogeneous resistance to vancomycin. We evaluated the efficacy of these combinations against Mu 3 and heterogeneously vancomycin-resistant S. aureus (hetero-VRSA) strains which were isolated from Korean patients using a population analysis method. Antag...

Background and Objective: Vancomycin is frequently the antibiotic of choice for the treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA). For the last years, the incidence of vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA) has been increased in various parts of the world. The present study ...
