title: Characterization of new staphylococcal cassette chromosome mec (SCCmec) and topoisomerase genes in fluoroquinolone- and methicillin-resistant Staphylococcus pseudintermedius.
abstract: Fluoroquinolone- and methicillin-resistant Staphylococcus pseudintermedius isolates harbor two new staphylococcal cassette chromosome mec (SCCmec) elements that belong to class A, allotype 3 (SCCmec II-III), and to the new allotype 5 (SCCmec VII). Analysis of the complete nucleotide sequences of the topoisomerase loci gyrB/gyrA and grlB/grlA revealed mutations involved in fluoroquinolone resistance.
