INTRODUCTION Antifungal susceptibility testing assists in finding the appropriate treatment for fungal infections, which are increasingly common. However, such testing is not very widespread. There are several existing methods, and the correlation between such methods was evaluated in this study. METHODS The susceptibility to fluconazole of 35 strains of Candida sp. isolated from blood cultur...

We investigated the performance of blood and chocolate agar as alternatives to Middlebrook 7H11 agar for testing the susceptibility of Mycobacterium tuberculosis to first-and second-line drugs by the Etest method. A total of 39 strains of M. tuberculosis including 22 multidrug-resistant M. tuberculosis strains and 17 susceptible strains were tested. In conclusion, our results showed that chocol...

Methods A total of 22 isolates, K. pneumoniae (n=20), Escherichia coli (n=1) and Enterobacter aerogenes (n=1), were collected from a university hospital, in Lisbon, Portugal. MIC were determined by Etest and interpreted according to Clinical and Laboratory Standards Institute guidelines. PCR was performed with primers designed to amplify blaSHV, blaTEM and blaKPC genes. Molecular typing was per...

OBJECTIVES We investigated vancomycin-intermediate Staphylococcus aureus (VISA) and heterogeneously vancomycin-intermediate S. aureus (hetero-VISA) isolates from clinical specimens of hospitalized patients at Hacettepe University over a 4 year period. METHODS Strains were screened for VISA and hetero-VISA by using brain heart infusion agar containing 4 mg/L vancomycin (BHI-V4) and macro Etest...

Sir, During the past 4 years, isolation of Candida inconspicua from clinical samples has increased in our laboratory. Fluconazole MIC values for C. inconspicua isolates are relatively high, as determined by standard broth microdilution (BMD), Etest or Fungitest, – 4 and according to the standard BMD method they fall mainly into the susceptible-dose dependent (S-DD) or resistant (R) categories, ...
