that not all gyrA or gyrB mutations confer the same level of quinol one resistance(4,5). Finally, no mutation to the gyrAAsp87 codon was identified in the 17samples resistant to nalidixic acid, while at gyrA Ser83 codon, 6strains showed type Ser83‐Leu mutations and one strains how edaSer83‐Alamutations, while the rewasno mutation identifieding yrB Asp426 and Lys447codons
