Spread of invasive Spanish Staphylococcus aureus spa-type t067 associated with a high prevalence of the aminoglycoside-modifying enzyme gene ant(4')-Ia and the efflux pump genes msrA/msrB

Abstract

A higher than expected prevalence of spa-type t067 isolates was found among invasive MRSA in Spain. The oxacillin, tobramycin, erythromycin and ciprofloxacin resistance profile of spa-type t067 isolates was linked to the presence of ant(4')-Ia and msrA or msrB genes.
