Project description:To determine if significant genomic changes are associated with the development of vancomycin intermediate Staphylococcus aureus, genomic DNA microarrays were performed to compare the initial vancomycin susceptible Staphylococcus aureus (VSSA) and a related vancomycin intermediate Staphylococcus aureus (VISA) isolate from five unique patients (five isolate pairs). Keywords: comparative genomic hybridization
Project description:Staphylococcus aureus CBS2016-05 and PS/BAC/317/16/W were spiked (4E+06 CFU/ml) into platelet concentrates (PCs) and Trypticase soy broth (TSB) and allowed to grow until early stationary phase (6 days) at 22-24°C. Subsequently, the cells were pelleted at 4°C and subjected to RNA extraction using the miRNeasy Mini Kit, following the manufacturer's instructions. To eliminate genomic DNA, the RNA samples from three independent biological replicates were treated with TURBO™ DNase AmbionTM (Thermo Fisher Scientific).
