Background This study introduces a newly created strain (Rhodococcus equi EtBr25) by
exposing R. equi ATCC 33701 to ethidium bromide (EtBr), a substrate for MDR transporters …

The req_39680 gene, associated to a putative efflux system, was detected in 60%(54/90) of
R. equi isolates by PCR. The phenotypic expression of efflux mechanism was verified in …

Rhodococcus equi is an important etiologic agent of respiratory-and non-respiratory tract
infections, diseases of animals and humans. Therapy includes the use of various group of …

Objectives The aim of this study was to determine the MICs of 32 antimicrobial agents for
200 isolates of Rhodococcus equi of animal origin by applying a recently described broth …

Objectives Study the rifampicin resistance of Rhodococcus equi strains isolated from French
horses over a 20-year period. Methods Rifampicin susceptibility tested by disc diffusion and …

Clonal multidrug resistance recently emerged in Rhodococcus equi, complicating the
therapeutic management of this difficult-to-treat animal-and human-pathogenic …

Objectives By adapting an antibiotic-susceptible Staphylococcus aureus strain to increasing
concentrations of ethidium bromide, a known substrate of efflux pumps (EPs), and by …

Objectives The objective of this study was to identify the molecular mechanism of macrolide
resistance in the actinomycete Rhodococcus equi, a major equine pathogen and zoonotic …

Objectives To analyse the efflux-mediated response of Staphylococcus epidermidis to
ethidium bromide (EtBr), a substrate of multidrug efflux pumps (EPs). Methods The …

The number of multidrug-resistant strains of Riemerella anatipestifer continues to increase,
and new strategies for the treatment of associated infections are necessary. Recently …
