...<p>...The third nucleotide (CG<bold>A</bold>) at codon 529, which 
is a specific nucleotide of <italic>M. tuberculosis</italic> 
(<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" 
rid="B11">11</xref>), was not clearly determined by conventional PCR direct 
sequencing. Furthermore, PCR sequencing misidentified codon 531 as 
T<bold>C</bold>G, which reflects the rifampin-susceptible strain. However, 
the second nucleotide at codon 531, which is the most frequent site of
mutation related to rifampin resistance, was determined as 
T<bold>T</bold>G by nested PCR sequencing (Fig. <xref ref-type="fig" 
rid="F5">5</xref>, lower panel)....</p>...
