<jats:title>ABSTRACT</jats:title>
<jats:p>
The potential use of
<jats:italic>Bacillus anthracis</jats:italic>
as a weapon of mass destruction poses a threat to humans, domesticated animals, and wildlife and necessitates the need for a rapid and highly specific detection assay. We have developed a real-time PCR-based assay for the specific detection of
<jats:italic>B. anthracis</jats:italic>
by taking advantage of the unique nucleotide sequence of the
<jats:italic>B. anthracis rpoB</jats:italic>
gene. Variable region 1 of the
<jats:italic>rpoB</jats:italic>
gene was sequenced from 36
<jats:italic>Bacillus</jats:italic>
strains, including 16
<jats:italic>B. anthracis</jats:italic>
strains and 20 other related bacilli, and four nucleotides specific for
<jats:italic>B. anthracis</jats:italic>
were identified. PCR primers were selected so that two
<jats:italic>B. anthracis</jats:italic>
-specific nucleotides were at their 3′ ends, whereas the remaining bases were specific to the probe region. This format permitted the PCR reactions to be performed on a LightCycler via fluorescence resonance energy transfer (FRET). The assay was found to be specific for 144
<jats:italic>B. anthracis</jats:italic>
strains from different geographical locations and did not cross-react with other related bacilli (175 strains), with the exception of one strain. The PCR assay can be performed on isolated DNA as well as crude vegetative cell lysates in less than 1 h. Therefore, the
<jats:italic>rpoB</jats:italic>
-FRET assay could be used as a new chromosomal marker for rapid detection of
<jats:italic>B. anthracis</jats:italic>
.
