OBJECTIVE Fluoroquinolone (FQ)-resistant Mycobacterium tuberculosis (MTB) clinical isolates have emerged in many areas of the world. The aim of this study was to observe the molecular characterization of gyrA and gyrB genes in FQ-resistant MTB clinical isolates from Guangdong Province in China. MATERIALS AND METHODS A total of 62 MTB clinical strains were originally isolated from patients with pulmonary tuberculosis. The phenotype of susceptibility of each strain was determined by the… CONTINUE READING
