Detection of vancomycin susceptibility among clinical isolates of MRSA by using minimum inhibitory concentration method

Vancomycin minimum inhibitory concentrations using different susceptibility methods in Staphylococcus aureus isolates.

Correlation of Minimum Inhibitory Concentration Breakpoints and Methicillin Resistance Gene Carriage in Clinical Isolates of Staphylococcus epidermidis

Staphylococcus epidermidis is the most important member of coagulase negative staphylococci responsible for community and hospital acquired infections. Most clinical isolates of S. epidermidis are resistant to methicillin making these infections difficult to treat. In this study, correlation of methicillin resistance phenotype was compared with methicillin resistance (mecA) gene carriage in 55 ...

Reduced vancomycin susceptibility in porcine ST9 MRSA isolates

Porcine strains of livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA) have been recognized in many countries and have been shown to be able to cause human infection. Resistance to non-beta lactam antibiotics has been reported but non-susceptibility to vancomycin, which is known to occur in human MRSA, has so far not been observed in LA-MRSA. Such resistance is typically ...

Minimum Inhibitory Concentration of Cefotaxime by E-test Method on Klebsiella in Gorgan

Abstract Background and objectives: the increasing use of antibiotics, especially the third generation cephalosporins, is an important factor in the spread of antibiotic resistance in bacteria. The main reason for the development of resistance phenotype such as Extended Spectrum Beta Lactamas (ESBL) is the extensive use of broad-spectrum cephalosporins. In phenotypic survey, the Phenotyping c...

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...
