Editor's Pick Mechanisms of ResistanceA Novel, Widespread qacA Allele Results in Reduced Chlorhexidine Susceptibility in Staphylococcus epidermidisChlorhexidine gluconate (CHG) is a topical antiseptic widely used in health care settings. In Staphylococcus spp., the pump QacA effluxes CHG, while the closely related QacB cannot due to a single amino acid substitution.
MinireviewRole of Rifampin against Staphylococcal Biofilm Infections In Vitro, in Animal Models, and in Orthopedic-Device-Related InfectionsRifampin has been used as an agent in combination therapy in orthopedic device-related infections (ODRI) for almost three decades. The aim of this review is to provide data regarding the role of rifampin against biofilm infection in vitro, in animal models, and in clinical ODRI.
SusceptibilityRifampin Resistance in Staphylococci after Rifaximin Intake for Surgical Prophylaxis in Elective Colorectal SurgeryThe aim of our study was to determine whether rifampin resistance emerges in human skin staphylococci after oral intake of rifaximin for surgical prophylaxis. Rifampin-resistant staphylococci appeared on the skin of 32 out of 74 patients (43.2%) two weeks after prophylactic treatment with rifaximin.
