Melioidosis is caused by
Burkholderia pseudomallei
and is predominantly seen in tropical regions. The clinical signs and symptoms of the disease are nonspecific and often result in misdiagnosis, failure of treatment, and poor clinical outcome. Septicemia with septic shock is the most common cause of death, with mortality rates above 40%. Bacterial culture is the gold standard for diagnosis, but it has low sensitivity and takes days to produce definitive results. Early laboratory diagnosis can help guide physicians to provide treatment specific to
B. pseudomallei
In our study, we adapted host gene expression signatures obtained from microarray data of
B. pseudomallei
-infected cases to develop a real-time PCR diagnostic test using two differentially expressed genes,
AIM2
(

FAM26F
(

). We tested blood from 33 patients with
B. pseudomallei
infections and 29 patients with other bacterial infections to validate the test and determine cutoff values for use in a cascading diagnostic algorithm. Differentiation of septicemic melioidosis from other
sepsis
cases had a sensitivity of 82%, specificity of 93%, and negative and positive predictive values (NPV and PPV) of 82% and 93%, respectively. Separation of cases likely to be melioidosis from those unlikely to be melioidosis in nonbacteremic situations showed a sensitivity of 40%, specificity of 54%, and NPV and PPV of 44% and 50%, respectively. We suggest that our
AIM2
and
FAM26F
expression combination algorithm could be beneficial for early melioidosis diagnosis, offering a result within 24 h of admission.
