Genetic Characterization of Vga ABC Proteins Conferring Reduced Susceptibility to Pleuromutilins in Staphylococcus aureus

Genetic Characterization of Vga ABC Proteins Conferring Reduced Susceptibility to Pleuromutilins in Staphylococcus aureus Novel ABC Transporter Gene, vga (C), Located on a Multiresistance Plasmid from a Porcine Methicillin-Resistant Staphylococcus aureus ST398 Strain Characterization of Two Newly Identified Genes, vgaD and vatG , Conferring Resistance to Streptogramin A in Enterococcus faecium Stepwise Exposure of Staphylococcus aureus to Pleuromutilins Is Associated with Stepwise Acquisition of Mutations in rplC and Minimally Affects Susceptibility to Retapamulin Interaction of the GraRS Two-Component System with the VraFG ABC Transporter To Support Vancomycin-Intermediate Resistance in Staphylococcus aureus Daptomycin Nonsusceptibility in Staphylococcus aureus with Reduced Vancomycin Susceptibility Is Independent of Alterations in MprF Novel Apramycin Resistance Gene apmA in Bovine and Porcine Methicillin-Resistant Staphylococcus aureus ST398 Isolates Selection for High-Level Telithromycin Resistance in Staphylococcus aureus Yields Mutants Resulting from an rplB -to- rplV Gene Conversion-Like Event A mec A -Negative Strain of Methicillin-Resistant S taphylococcus aureus with High-Level β-Lactam Resistance Contains Mutations in Three Genes Contribution of vraSR and graSR Point Mutations to Vancomycin Resistance in Vancomycin-Intermediate Staphylococcus aureus
