ABSTRACT
Background & objectives:
Bacillus anthracis, Yersinia pestis, Burkholderia pseudomallei and Brucella species are potential biowarfare agents. Classical bacteriological methods for their identification are cumbersome, time consuming and of potential risk to the handler.Methods:
We describe a sensitive and specific multiplex polymerase chain reaction (mPCR) assay involving novel primers sets for the simultaneous detection of B. anthracis, Y. pestis, B. pseudomallei and Brucella species. An additional non-competitive internal amplification control (IAC) was also included.Results:
The mPCR was found to be specific when tested against closely related organisms. The sensitivity of the assay in spiked blood samples was 50 colony forming units (cfus)/25 μl reaction, for the detection of B. anthracis, Y. pestis and Brucella species; and 150 cfus/25 μl reaction, for B. pseudomallei. The assay proved useful in correctly and promptly identifing the clinical isolates of the targeted agents recovered from patients, compared to the gold standard culture methods. Interpretation &conclusion:
The assay described in this study showed promise to be useful in application as a routine detection cum diagnostic method for these pathogens.
