Fig. 1From: Fluoroquinolone resistance and mutational profile of gyrA in pulmonary MDR tuberculosis patientsThe frequency of amino acid and nucleotide change in fluoroquinolone resistant isolates. In general, amino acid change found in three amino acids: alanine (A into V), serine (S into P), and aspartic acid (D either into A, N, Y or G) and the corresponding nucleoide change to these amino acids is also representedBack to article page
