Journal ArticleDOI
Mutation frequencies for resistance to fusidic acid and rifampicin in Staphylococcus aureus
TL;DR: The results suggest that these antibiotics, when used in combination, could have a wider role in the management of staphylococcal infections.
Journal ArticleDOI
Molecular Genetic and Structural Modeling Studies of Staphylococcus aureus RNA Polymerase and the Fitness of Rifampin Resistance Genotypes in Relation to Clinical Prevalence
TL;DR: Intragenic mutations which compensate for the fitness costs associated with rifampin resistance in clinical strains of S. aureus were identified for the first time and obtained by molecular modeling of mutated RNA polymerase enzymes.
Journal ArticleDOI
Glycylcyclines: third-generation tetracycline antibiotics.
TL;DR: One of the glycylcyclines, 9-t-butylglycylamido-minocycline (GAR-936, tigilcycline), is currently undergoing clinical trials and microbiological, pharmacodynamic and pharmacokinetic data have recently been presented.
Journal ArticleDOI
Genetic Basis of Resistance to Fusidic Acid in Staphylococci
TL;DR: Resistance to fusidic acid in clinical isolates of S. aureus and other staphylococcal species frequently results from expression of FusB-type proteins.
Journal ArticleDOI
The Target of Daptomycin Is Absent from Escherichia coli and Other Gram-Negative Pathogens
TL;DR: It is shown that the antibiotic daptomycin, whose target appears to be absent from E. coli and other Gram-negative pathogens, demonstrates antibacterial activity against Gram negatives.
