Vancomycin and daptomycin minimum inhibitory concentration distribution and occurrence of heteroresistance among methicillin-resistant Staphylococcus aureus blood isolates in Turkey
BACKGROUND The aim of this study was to determine the distribution of vancomycin and daptomycin MICs among methicillin-resistant Staphylococcus aureus (MRSA) blood isolates, the prevalence of heterogeneous vancomycin-intermediate S. aureus (hVISA) and the relationship between hVISA and vancomycin MIC values. METHODS A total of 175 MRSA blood isolates were collected from seven university hospi...
متن کاملVancomycin 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...
متن کاملMinimum Inhibitory Concentration of Staphylococcus Aureus against Vancomycin
The main objective of this investigation is to find out the minimum inhibitory concentration (MIC) of Staphylococcus aureus with reduced inclination to vancomycin among 30 clinical isolates of methicillin-resistance Staphylococcus aureus (MRSA) and was screened by Etest and broth dilution methods. The comparative analysis of MIC for vancomycin by broth dilution and Etest methods discloses that ...
متن کاملEffect of vancomycin minimal inhibitory concentration on the outcome of methicillin-susceptible Staphylococcus aureus endocarditis.
BACKGROUND Staphylococcus aureus endocarditis has a high mortality rate. Vancomycin minimum inhibitory concentration (MIC) has been shown to affect the outcome of methicillin-resistant S. aureus bacteremia, and recent data point to a similar effect on methicillin-susceptible S. aureus bacteremia. We aimed to evaluate the effect of vancomycin MIC on left-sided S. aureus infective endocarditis (I...
متن کاملVancomycin heteroresistance in bloodstream isolates of Staphylococcus capitis.
Nine Staphylococcus capitis isolates from blood cultures of newborns were examined for resistance to vancomycin. MICs were within the susceptible range, but population profiling revealed a resistant subpopulation. Only isolates with the largest subpopulation were identified as heteroresistant to vancomycin by Etest. This finding may have therapeutic implications.
